Main cooling cycle: Low-pressure mixed refrigerant exits the user’s cold box and is drawn into the main cooling compressor. After compression, it becomes a high-temperature, high-pressure gas. It then enters an oil separator to remove most of the lubricating oil, then enters a high-efficiency degreaser to remove any remaining lubricating oil. It then enters the main cooling system’s aftercooler for heat exchange with air/water. The heat released is carried away by the air/water, and the mixed refrigerant finally enters the cold box.
Precooling cycle: Using propane (R290) as the refrigerant, low-temperature, low-pressure refrigerant exits the user’s cold box and is drawn into the precooling compressor. After compression, it becomes a high-temperature, high-pressure gas. It then enters an oil separator to remove most of the lubricating oil, then enters a high-efficiency degreaser to remove any remaining lubricating oil. It then enters a condenser for heat exchange with air/water, where the heat released is carried away by the air/water. After condensing into a liquid, the refrigerant enters the cold box.
The screw compressor adopts a semi-enclosed structure design with no shaft seal and zero leakage; the unit is assembled in the factory and transported as a whole on a skid, which reduces the amount of on-site construction and shortens the construction period.
Ice wheel mixed refrigerant screw compressor unit is mainly used in small natural gas liquefaction to LNG, light hydrocarbon recovery, BOG gas, helium recovery and other industries.
