As a gas booster, the propylene compressor increases the pressure and temperature of the propylene medium through compression, enabling energy transfer and conversion in process cycles (such as refrigeration and distillation). In heat pump distillation cycles, the compressor adiabatically compresses and heats the overhead gas (99.6% propylene + 0.4% propane), converting it into a reboiler heat source, achieving efficient recycling of hot and cold streams. In refrigeration systems, gaseous propylene undergoes multi-stage compression before condensing into a liquid state in the condenser, completing the refrigeration cycle. Airflow pulsation within the compressor is the main cause of excessive vibration in the outlet pipeline; excessive pressure unevenness and insufficient buffer tank volume can lead to engineering problems such as gas column resonance.

Propylene compressors can be configured in various structural forms, including vertical and symmetrical balanced types, all featuring an oil-free reciprocating piston design to ensure the purity of the working medium. These compressors are characterized by low vibration, low noise, and stable operation. They are available in mobile, stationary, or vehicle-mounted configurations.
