CHP : Combined Heat and Power Plant
◈ Offgas compressors are used to recover the gas contained in the liquid after the liquid and gas are separated in the natural gas that is sent from the gas field wellhead.
◈ Offgas compressors have a high difference between the intake and discharge pressures and handle high-density gases. For this reason, consideration must be given to shaft vibration issues as well as to strength.
◈ Regeneration gas compressors are used in the acid gas removal equipment.
◈ In the same way as with offgas compressors, there is large variation in the gas molecular weight depending on the operating conditions, and a broad operating range is required.
◈ Main refrigerant compressors are used to compress the refrigerant gas to cryogenic heat exchangers in the cooling circuit in the main liquefaction process.
◈ This type of compressor is required to extremely precise fluid dynamic design to predict the performance of the compressor in the various operating conditions at site.
◈ End flash gas compressors are used to compress the low-pressure vapor which is produced after liquefaction facility or at LNG tank to fuel gas for gas turbine or other process.
◈ When the vapor is produced at LNG tank only. Those are called Boil off compressor.
◈ This type of compressor is required to design for low intake temperatures of approximately -162℃.
◈ This means that the compressor must be made of materials to endure the low temperature conditions.
◈ Fuel gas supply compressors allow the gas remaining after LNG was produced from the raw gas to be used as plant fuel gas for the main drive gas turbines and other systems.
◈ This type of compressor is characterized by low intake temperatures of -60°C or below. This means that the compressor must be made of materials with refrigeration system specifications.
