China Methane Compressor - Reliable Suppliers & Factory Equipment for Safe Gas Handling
Methane Diaphragm Compressor Advantages
Ultimate Purity and Absolute Safety:
The static sealing structure of the diaphragm chamber achieves physical isolation between the gas and lubricating oil, ensuring the purity of compressed methane is as high as 99.999%, while completely eliminating gas leakage during operation. This perfectly matches the flammable and explosive nature of methane, providing the highest level of protection for chemical-grade methane, laboratory research, and safety-sensitive areas.
High Pressure Capability and Wide Adaptability:
A single stage can achieve a high compression ratio, with a maximum discharge pressure of up to 100 MPa. It can meet ultra-high-pressure requirements ranging from CNG filling and high-pressure bottling to special chemical processes. Its corrosion-resistant material options also allow it to handle methane gas sources containing trace impurities.
Methane Diaphragm Compressor Design Points
Diaphragm Safety Monitoring and Material Upgrade:
A three-layer diaphragm structure must be configured with an integrated rupture monitoring and alarm system to ensure immediate interlock shutdown upon diaphragm failure, preventing oil-gas mixing. All flow-wetted parts must be made of 316L stainless steel or a higher-grade material and undergo strict degreasing and cleaning to guarantee gas purity and material compatibility.
Precise Thermal Management and Leak Prevention Design:
The discharge temperature of each stage must be strictly controlled, typically not exceeding 120–135°C, to prevent the impact of high temperature on diaphragm life and sealing materials. All static sealing points in the gas path system must adopt metal seals or high-performance sealing elements. Nitrogen purging interfaces must be provided for purging before startup and maintaining pressure after shutdown to prevent the formation of explosive mixtures.
Integrated Safety Interlock System:
Methane-specific combustible gas detectors must be installed within the compressor skid scope and interlocked with the main engine Emergency Shutdown (ESD) system and emergency ventilation system. Dual alarms and shutdown interlocks must be set for pressure and temperature parameters to establish an active safety protection system.
