difference between reciprocating and centrifugal compressors pdf

A semi-hermetic uses a large cast metal shell with gasketed covers that can be opened to replace motor and pump components. KB Delta manufactures and stocks a complete range of metallic compressor valve plates and rings for the natural gas, refrigeration and P.E.T. Reciprocating air compressors, which are also called “piston” or “recip” air compressors, are widely used throughout various service industries due to their price and availability. IGOR J. KARASSIK Late Senior Consulting Engineer, Ingersoll-Dresser Pump Co. JAMES L. BOWMAN Senior Engineering Consultant, Rotary-Reciprocating Compressor Division, Ingersoll-Rand Co. BENJAMIN B. DAYTON Consulting Physicist, East Flat Rock, NC. In hydrogen-rich gas applications, API 618 (2007) limits discharge temperatures to 135 deg C. For natural gas service the maximum discharge temperature limit is 175 deg C. However, a more practical limit followed is 149 deg C. Air compressor discharge temperature limits may be as high as 200 deg C. Flow range of a centrifugal compressor is determined by the surge and choke points. Reciprocating Compressor/Natural Gas Industry ©.Privacy PolicyKB Delta, Mfg, Valve Seat and Seat Ring Basics: What to Know, The Business Benefits of Green Manufacturing, Types of Bearings in Reciprocating Compressors, and Their Importance. The lowest temperature requirement for centrifugal compressors is typically found in LNG boil-off gas applications. Production boosting. Both reciprocating and centrifugal compressors are valuable in the manufacturing world. On the other hand, if the pressure ratio is less than two when a centrifugal compressor is in use, its efficiency is higher. The compression principle of centrifugal compressor is quite different from that of reciprocating or rotary type compressor. Double-Acting Compressors: It has two sets of suction/intake and delivery valves on both sides of the piston. For reciprocating compressors, maximum as well as minimum flow is directed by the size of its cylinder, as well as the amount of cylinders available. Because reciprocating compressors run intermittently and with air which pulsates at a high pressure ratio, they handle a smaller volume of air than centrifugal compressors. Before moving to further detailed explanation lets have some overview of Centrifugal and Reciprocating Pump. They are divided into rotary (lobe, screw, scroll, vane and liquid ring compressor) and reciprocating (diaphragm, single and double acting compressor). Lead time for a centrifugal compressor train range from 35 to 75 weeks. A centrifugal compressor has fewer wearing parts, resulting in lower operating costs in terms of replacement parts, repairs, and downtime. Where centrifugal compressors are concerned, they score higher on isentropic efficiency: They tend to range from anywhere between 70 to 95 percent, depending upon. Process equipment such as scrubbers and coolers and process control valves are typically installed at site. II. I explained this difference by using number of technical point. About the Author: This article is written by Mr Ankur Srivastava, a Chemical Engineer with more than 32 years of process engineering experience in oil and gas, refining, polymers and petrochemical industries.eval(ez_write_tag([[300,250],'whatispiping_com-box-4','ezslot_8',635,'0','0'])); I am a Mechanical Engineer turned into a Piping Engineer. Reciprocating compressors are affected by aerosol contaminant primarily in the piston cylinder intake/exhaust. Reciprocating 749 3.5 Work, Temperature Rise, and Efficiency of Compression 749 BIBLIOGRAPHY 752 1 INTRODUCTION TO FLUID MOVERS Pumps, fans, blowers, and compressors are all devices that move fluids across an adverse pressure difference, i.e., from a … However, problems with pulsation and mechanical reliability cause these compressors to be less desirable than centrifugal compressors for … Process plant optimization. The engine can consist of two to six pistons per cylinder, depending upon horsepower demands. Revision 0 White Paper 254 by Paul Lin Victor Avelar . Reciprocating compressors are made of very common materials such as gray iron, ductile iron, carbon steel, stainless steel, and alloy steel. Your email address will not be published. Because they consist of one stage, they are easier to stop than centrifugal compressors, and can be installed more quickly. The installation time varies widely depending on the size of the compressor. Reciprocating compressor deliver gas with high pressure and mass of flow rate small due to reciprocation motion.it is used for less mass flow rate.etc mostly used pneumatic air. This is primarily due to the fact that centrifugal compressors require parts with more complex geometry such as impellers and diaphragms. When the air passes through the rotating impeller it experiences force or work which is performed by centrifugal forces. This industry manufactures blow molding machinery. Both sides of the piston are utilized in compressing the air. The piston rod load generated by the compression ratio may also be a limit. Welcome to my space, I am Anup Kumar Dey, an experienced piping engineer from the last 15 years. Centrifugal compressor deliver gas with low pressure and mass flow rate high due to centifugal mation.it is used for high mass flow rate.etc mostly used in turbine. When the compression efficiency in a system is greater than two on a reciprocating compressor, it operates at greater efficiency than a centrifugal compressor. This means that the ratio of energy expended to isothermally compress any gas compares favorably to the amount of work done by the system. Maintenance requirements for reciprocating compressors vary significantly with the application and follow maintenance patterns very much based on what has been described in the reliability section. plastic bottle manufacturing industry. Typical flow range might be from 100%, down to 20%, or even lower. Reciprocating compressors can be found in wastewater treatment plants or systems for which single-stage processes are appropriate. Usually, in centrifugal compressors, efficiency can be compromised by mechanical problems or leakage within the system. Because of the way both compressors are constructed and operated, their mechanical efficiency is different. | Find, read and cite all the research you need on ResearchGate For the most part, the difference between reciprocating and centrifugal compressors lies in their construction and style of operation. ! 2. This could be in cast, forging, or bar stock form. We manufacture our own springs and stock over 2 million springs for a variety of OEM spring styles, forms and materials. Installation time for these might vary from a few days to a couple of weeks. Lead time for a bare compressor will vary from 14 to 40 weeks depending on size and manufacturer. ightly loaded journal bearings, such as those used in compressors, can he unstable at high speeds, and a … Auxiliary systems such as lube oil consoles, control panels, and seal buffer systems may also be installed separately. Since reciprocating compressors have many more parts and more rubbing seals (pressure packing, piston rings, and rider rings) that wear and require more frequent replacement, they are considered somewhat less reliable than centrifugal compressors. For the same operating conditions a reciprocating compressor will consume less power per unit volume flow. What Are the Signs of Failed Valve Seals? The reason for higher operating cost is due to more wearable parts requiring frequent maintenance and leading to higher machine downtime. Despite their smaller size, centrifugal compressors tend to be used in industrial applications rather than in the home. Required fields are marked *. Centrifugal compressors are generally classified as turbocompressors and tend to offer a narrow operating range. Reciprocating compressors have a very characteristic adiabatic efficiency curve. The maximum and minimum flow of centrifugal compressors is affected by its choke point and surge (or amount of system resistance and ambient environmental conditions), and usually performs well at flow rates below300 m3/h. Reliability / availability of centrifugal compressors is typically 98 to 99%. Mechanical Balance: Poor mechanical balance and greater vibrations due to presence of reciprocating masses. On low compression ratio applications (compression ratio less than 1.6, such as pipeline transmission of natural gas) adding fixed clearance will hardly change the flow. Both light and heavy gases are compressed very well. There are various types of compressors used in the refrigeration and air conditioning machines, these are: reciprocating, rotary, screw, centrifugal and scroll. However, a centrifugal compressor has fewer wearing parts, resulting in lower operating costs in terms of replacement parts, repairs and downtime. For corrosive applications it is common to use stainless steel such as 17-4PH or 400 series for piston rods and compressor valve seats and guards. 1. Reciprocating Compressors have the ability to change flow through speed control, the addition of fixed clearance to a cylinder (fixed or variable volume clearance pockets), cylinder end deactivation, and gas recycle. Polytropic efficiencies are used for centrifugal compressors rather than adiabatic efficiencies. In the pump-priming process, the pump is filled with the liquid... Hi There! Their high horsepower and relatively lower weight mean that while they might consume more resources, they can be suitable for manufacturers looking for a more compact compressor. Efficiency changes with molecular weight too. Let’s take a closer look at the many ways reciprocating compressors and centrifugal compressors are different. Understanding how and why they are different can assist in making an informed decision. The number of different services on a given compressor crank case (frame) is only limited by the throws available and the number of stages required for each service. Due to these elements, centrifugal compressors are typically used in gas and oil extraction and production. Maintenance requirements are typically limited to replacing bearing pads and seal wearing parts. The main differences between Centrifugal Pump and Reciprocating Pump are the Centrifugal pump works low medium pressure head and Reciprocating Pump works high medium pressure head. Reciprocating compressors are used in refineries, gas pipelines, chemical and petrochemical plants, natural gas processing plants and refrigeration plants. Cost: Capital and Operating • Reciprocating—Generally a reciprocating compressor will have a lower capital cost since centrifugals use complex geometry parts but recips have a higher operating cost compared to a centrifugal. Considering a centrifugal compressor with a water wash system, the end user may exhaust their reverse osmosis water supply, or the system freezes and there are extended periods without online washing. Discharge temperature limits will depend on the application (gas compressed) and the seal element materials selected. For example, very low molecular weight gases may present seal challenges and very high molecular weight gases may present challenges related to compressor efficiency. Piping and wiring from these auxiliary systems and process equipment to the compressor train are typically done at site. Compressor valve and seal elements may require to be maintained in durations as short as a few months and as long as 3-5 years.

It includes most medical devices which aid the prevention, diagnosis and treatment of diseases and illnesses. link to Flange Bolt Torque Calculation and Pipe Flange Bolt Torque Chart, Difference between Centrifugal and Reciprocating Compressor, For more details about Centrifugal Compressors Click here, Click here to know more about Reciprocating Compressors, Flange Bolt Torque Calculation and Pipe Flange Bolt Torque Chart, They can be sized for an inlet flow of 680,000 actual m. Capacity is limited by cylinder size, the number of throws available, and the available driver speeds. Reciprocating pumps discharge fluid in pulses, with each … FIGURE 7-7 Cutaway of a Reciprocating Compressor Courtesy of Bayport Training & Technical Center In theory, reciprocating compressors are more efficient than centrifugal com- pressors. In this video, I explained difference between reciprocating and centrifugal pump. Reciprocating compressors, because of their multistage operation and low discharge, can invite cracking and potentially affect the health of their operators due to their greater noise and vibrations. In other applications with higher compression ratios, clearance pockets and cylinder end deactivation are commonly used to regulate flow. These dynamic compressors pull in air to their centers with radial blades. Among other types used are rotary vane, diaphragm, liquid ring, and axial compressors. For a specific gas, the limits to compression ratio are the mechanical and rotordynamic limitations on speed and the number of stages that can be accommodated in a single body. Reciprocating Compressor. Electrical motor driven reciprocating compressors may require longer lead times specifically if large high horsepower motors are required. Generally a reciprocating compressor will have a lower capital cost but a higher operating cost (excluding power consumption). Dynamic Compressors. Packaged compressors up to 3.4 MW and of a high-speed short stroke design are common today. Click here to know more about Reciprocating Compressors. The lowest suction temperatures required typically are in LNG boil-off applications with requirements as low as -170 deg C and there are very limited manufacturers for this application. Ejector •Quiet operation •High volume of air, steady flow. Before moving to further detailed explanation lets have some overview of Pump and compressor. Often the lead time is governed by the driver (electric motor / turbine) since these are generally made to order. The air is compressed only on the top part of the piston. Centrifugal compressors operate on a constant pressure, and personnel must tend to their external environment to ensure efficient flow. Now let’s understand differences between Centrifugal Pump and Reciprocating Pump with the help of table given below. For reciprocating gas engine driven large compressors the lead times may be shorter. Single-Acting Compressors: It has piston working on air only in one direction. Typical polytropic efficiencies range from 70% to 85%. Major machine overhaul including bearing replacement may be required after 10 years of operation or longer. Installation time for a typical motor / gear driven compressor package is 2-3 weeks. Deciding between which to invest in requires research and careful study of a system’s needs and a good understanding of operating conditions. The gas which is produced by a reciprocating compressor is either fed to a pneumatic system or immediately stored. Typical turndown for a fixed speed, multi-stage centrifugal pump is approximately 20-30%. Location can also be a factor. SYMBOLS AND UNIT Designation Symbol Unit Pressure p bar A Temperature t C Absolute Temperature T K Capacity (volume flow) Q m3 / hr Power P kW Brake horse power BHP kW Gas horse power GHP kW Speed N RPM Head (polytropic) H m Gas Constant R kJ/kg.K Molecular Mass MW … High discharge temperatures due to high compression ratios can usually be controlled by inter-cooling between a compression stage. Figure 21.1 shows the working principle of a centrifugal compressor. Established centers of this industry include the United States and Western Europe. Sr. No. Some compressor pistons and covers maybe made of aluminum. Components may be cast, forged, or machined. Section 14 Fans, Pumps, and Compressors BY T. L. HENSHAW Consulting Engineer, Battle Creek, MI. Through this platform, I will share my experiences and knowledge with you in an innovative way. Head is developed by increasing gas velocity to create kinetic energy and then converting the kinetic energy to pressure in the diffuser. They are also found on jet engines. The capital cost of a centrifugal compressor is typically higher than a reciprocating compressor operating at the same conditions. The application will determine what type of capacity control method is required and used. Another reciprocating compressor component are compressor valves (simple spring-loaded check valves) which require frequent maintenance and … Their use depends greatly on function, location, and environmental considerations. Operating principle of Pump and Compressor 3. When a gas-driven reciprocating compressor is experiencing failure, operators are usually warned by easily discernible symptoms. Remote or offshore locations can add to installation time. In this paper, each of these compressors is defined, benefits and limita-tions are listed, and practical applications of each are discussed. Special compressors known as hypercompressors used in the low density polyethylene manufacture will generate pressures as high as 3500 barg. Typical compression ratios for one stage are 1.2 to 4.0. Over the range of molecular weight different application configurations may be required. The main difference between centrifugal and reciprocating pump is that, in centrifugal pumps, the fluid is continuously accelerated by a set of impeller blades whereas, in reciprocating pumps, the periodic motion of a piston draws in and discharges fluid. There is a variety of different types of pumps which are used in different situations. Today we will discuss about difference between centrifugal pump and reciprocating pump. Compressors are an essential part of every industry, but what’s the difference between a centrifugal vs reciprocating compressor? Compressor valves happen to be one of the most wearable parts in a reciprocating compressor. Pressure Ratio per Stage: High upto 5-8. It is recommended that for flow rates of actual 300 m, Similar to the maximum flow, the minimum flow in a reciprocating compressor is limited by the cylinder size, stroke, and speed. Difference between Centrifugal & Reciprocating Compressors! Customized designs would be required which could handle different gases simultaneously. This website is my first venture into the world of blogging with the aim of connecting with other piping engineers around the world. The compressor and driver are typically packaged on a base plate complete with oil piping and wiring to junction boxes. Also known as throttling or capacity control. The gas in the inlet section is compressed by the reciprocating motion of the pistons. Low temperature seals and O-Rings are also required. The technology which powers centrifugal compressors dates to the 1940’s, so, since the trial-and-error phase of testing the scientific principals which drive them are well past, centrifugal compressors tend to be more available, more reliable, and less prone to maintenance needs. Main components of centrifugal compressor are Casing, Shaft, Impellers, Bearings, Diaphragms and Seals. The compressors are one of the most important parts of the refrigeration cycle. PDF | Control Methods for centrifugal compressors, especially in oil and gas service. (For reciprocating, rotary screw, and centrifugal) 21 Modulation: restricts inlet air to the compressors to reduce compressor output to a specified minimum. Since reciprocating compressors have many more parts and more rubbing seals (pressure packing, piston rings, and rider rings) that wear and require more frequent replacement, they are considered somewhat less reliable than centrifugal compressors. Centrifugal compressors are designed for large capacity systems. Materials for major components such as casings, nozzles, shafts, impellers etc. The dynamic ones are further separated into centrifugal and axial. Centrifugal pump which is also known as rotary pump used kinetic energy of impeller to force the fluid and increase its kinetic energy. Centrifugal pump is a rotodynamic pump that uses kinetic energy to transfer fluid from low pressure to high pressure while the reciprocating pump uses a piston (suction and discharge stroke) to transfer fluid. While centrifugal compressors accomplish the same results as the previously described compressor types, they go about it in an entirely different way. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. Reciprocating compressors usually operate with better isothermal efficiency. The main difference between Pump and compressor is the pump transfers liquid from one place to another place whereas the compressor is used for storage of squeezed gas and then it supplied at the required place. A buildup of contaminants on the valves can lead to sticking valves or valves with partial bypass, resulting in a reduced compression ratio and increased power consumption. The work input takes place as an increase in pressure and velocity or speed of the air flow through the impeller. They are designed to work in several stages.

When a reciprocating compressor is activated, gas injected into the piston’s cylinders is compressed as the pistons reciprocate. Contact us today. Between these stages, moisture which accompanies rises in pressure is removed from the system, and the air is rapidly cooled. KB Delta specializes in manufacturing compressor valve parts for high pressure air compressors used in the P.E.T. Our specialized precision tooling and proprietary lapping process gives our customers the highest quality thermoplastic plates and rings in the industry. The contents of the above article are produced in a tabular manner with minor modifications based on various other sources and the author’s own understanding. Reciprocating compressors are usually found in air cooled direct expansion (DX) systems for residential and small commercial systems. Such an application may require speed control or cylinder end deactivation. Typical reciprocating compressors in the process industry are used to generate discharge pressures as high as 800 barg. Reciprocating compressors can also work in a minor vacuum as long as air does not leak into the system. about different compressor types and their characteristics. Unlike reciprocating compressors, centrifugal compressors are steady-flow devices hence they are subjected to less vibration and noise. Another reciprocating compressor component are compressor valves (simple spring-loaded check valves) which require frequent maintenance and replacement.
