Abstract:
The critical speed is a crucial factor that impacts the stability of high-speed compressors. However, limited research has simultaneously considered the influence of gas foil bearings (GFBs), labyrinth seals, and impellers on critical speed. In this study, we develop a rotordynamic model that incorporates the aerodynamic forces of GFBs, labyrinth seals, and impellers to explore the effects of each component on the critical speed. To validate the developed model, experimental tests are conducted on a centrifugal compressor test bed, and the results exhibit a high level of agreement with the mod

Introduction. The article presents studies of the possibility of increasing gas pressure in one stage. Reciprocating compressors of road construction machines have been investigated, for which, as for any mobile stations, the issue of reducing the weight and size parameters of process equipment is acute. In this regard, the aim of the work was to expand the range of pressures obtained in single-stage piston machines. An alternative to the use of existing compressors with lubricated flow part can be compressors with seals based on fluoroplastic compounds that do not require liquid lubrication.

Abstract:
Centrifugal compressors are widely used to compressor gas in many different processes within the petroleum and chemical industry. Two vibration types of concern in industrial compressors are synchronous and subsynchronous vibration. The latter, more troubling type of vibration, occurs when non-conservative whirling forces(Cross-coupling) act to excite a lateral natural frequency, which lies below the running speed(subsynchronous vibration). In this paper, more attention is paid to impellers from a rotordynamic standpoint and a synthesis gas compress in ammonia plant is analyzed in order to dia

Both of them are low-flow, high-pressure, high rotational speed compressors, and are fitted with tilting pad bearings and dry gas seals.

Then, aerodynamic excitations caused the rotors to operate at their stability limit, and high vibration levels were observed at the first natural frequency.

Abstract:
Seals are considered one of the important flow elements of a turbomachinery device. Traditional labyrinth seals have proven their performance functionality by reducing leakage rates. Significant improvements on labyrinth seal functionality were obtained through altering the design geometry of labyrinth seals to prevent contamination across a seal and maintaining small leakage flowrates. This results in a windback seal that has only one tooth which continuously winds around the shaft like a screw thread. These seals are used in gas compressors to isolate the gas face seal from bearing oil. A pu

Основной отличительной особенностью работы центробежных компрессоров (ЦК) в составе дожимных компрессорных станций является работа при переменном (снижающемся) давлении газа на входе и необходимости обеспечения постоянного значения давления на выходе. Это требует применения компрессоров, обеспечивающих высокие значения отношений давлений. Работа таких компрессоров характеризуется небольшим объемным расходом компримируемого газа, по сравнению с компрессорами линейных компрессорных станций, что пропорционально увеличивает влияние протечек в межступенчатых уплотнениях на эффективность работы ЦК.

It was found that the top surface layer of the abradable liner degrades over its lifetime. During thermal cycling hBN is removed from the material’s microstructure, which results in the degradation of the abradable and increased brittleness of the top surface.

Abstract:
Abstract Gas compressor customers desire to operate gas compressors at higher discharge temperatures. In barrel-style centrifugal compressors, dry gas seals are used to limit the leakage along the shaft from the process fluid to atmosphere. The temperature limit of dynamic O-ring seals in the dry gas seal cartridge is one of the primary limiters to operating gas compressors at higher discharge temperatures. While the present discharge temperature limit is conservative compared to the seal limits, without a detailed understanding of the thermal distribution around the discharge-side end cap, op

Abstract:
Reviews current technology of internal labyrinth seals and concludes that internal leakage can reduce compressor efficiencies as much as 3 to 6 percent. Discusses limitations on abradable seals with tighter clearances and the effect of compressor surge on both types of seals. Proposes resiliently mounted seals as subject for future investigation to accommodate rotor movement without excessive seal wear.

Abstract:
The Methane Emissions Reduction solution designed by Solar Turbines was installed and evaluated at the Berkshire Hathaway Energy (Dominion) Chambersburg station in Pennsylvania, USA. Solar Turbines supplied a dry seal recompression (DSR) system and a process vent recompression (PVR) system at the station. The objective of the field trial was to evaluate the durability of this new system, compare the performance in the field to simulation models and as needed make improvements to the mechanical design and/or software control. The dry gas seal recompression system was installed and connected to

Abstract:
In 2008, Pipeline Research Council International (PRCI) took the initiative to identify the main causes of reportable incidents in compressor and pump stations. Data was gathered from several sources including the United States� Department of Transportation Pipeline and Hazardous Materials Safety Administration, Canada�s National Energy Board, and PRCI member companies. More than 1600 incidents were reviewed over an 18 year period (1990 to 2008). The incidents were evaluated based on their frequency of occurrence and the consequences of the incidents (injury, ignition, environmental impact, et

Abstract:
The U.S. EPA Greenhouse Gas (GHG) Reporting Program (GHGRP) requires compressor stations and underground storage facilities to measure compressor vent, rod packing, and seal emissions for facilities subject to 40 CFR, Part 98, Subpart W. The objective of the project is to gather and evaluate 2011 - 2016 Subpart W compressor vent and seal methane emissions data from site measurements, and present final results of an analysis to develop methane Emission Factors (EFs) based on these data. The EFs and analysis of relative contribution from different sources can be used: (1) as alternatives to curr

Abstract:
A 2018 PRCI report evaluated related emissions from compressor seals, isolation valves, and blowdown valves based on direct measurements required by Subpart W of the GHG Reporting Program. This report presents the methane emissions data from 2011 - 2016 for the balance of the Subpart W emission sources, including: facility leaks (other than from compressor isolation valves and blowdown valves), pneumatic controller venting, condensate tank dump valve leakage, and blowdown emissions from stations. Transmission pipeline blowdown emission reporting was added to the EPA regulation in late 2015, an

Abstract:
The Pipeline Research Council International, Inc. (PRCI) seeks to reduce greenhouse gas (GHG) from leaks and equipment emissions from all parts of the hydrocarbon transport and storage infrastructure. Specifically, there is a need to identify and compare cost-effective technologies that can detect and quantify leaks or emissions from compressor rod packing and seals, scrubber dumps, and blowdown valves. Furthermore, regulations are increasingly prescriptive and are moving from conventional leak detection and repair (LDAR) programs to direct quantification and/or period/continuous monitoring of
