    Methane Diaphragm Compressor Advantages
    01

    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.

    02

    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
    01

    Diaphragm Safety Monitoring

    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.

    02

    Precise Thermal Management

    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.

    03

    Integrated Safety Interlock

    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.

    Frequently Asked Questions
    What is the purity level of the compressed methane gas?
    The static sealing structure of the diaphragm chamber physically isolates the gas from the lubricating oil. This ensures that the purity of the compressed methane is maintained up to 99.999% without oil contamination.
    How does the compressor ensure safety with flammable methane gas?
    Safety is achieved through a multi-tiered protection system: a three-layer diaphragm with rupture monitoring, metal seals to prevent leakage, nitrogen purging interfaces, and integrated combustible gas detectors linked directly to the Emergency Shutdown (ESD) system.
    What is the maximum discharge pressure capacity?
    A single stage can achieve a high compression ratio, with a maximum discharge pressure of up to 100 MPa. This fits ultra-high-pressure applications like CNG filling, bottling, and chemical processes.
    What materials are used for parts that come in contact with the gas?
    All flow-wetted parts are made of 316L stainless steel or higher-grade corrosion-resistant alloys. Additionally, they undergo strict degreasing and cleaning procedures to ensure absolute material compatibility and gas purity.
    How is the operating temperature managed in these compressors?
    The discharge temperature of each stage is strictly controlled and typically kept below 120–135°C. This precise thermal management protects the diaphragm life and prevents damage to the sealing materials.
    What cooling methods are available for the Model Selection?
    Depending on the specific model (GZ, GV, GL, or GD) and operational requirements, both water-cooled and air-cooled configurations are available to suit different industrial environments.
