cryogenic compressor for low-temperature ethylene transport

Cryogenic compressors are specifically engineered to handle cryogenic ethylene and other deep-cooled gases, enabling the pressurization, transportation, and recovery of gases at temperatures from -30°C to -160°C. They ensure reliable and stable operation for key industrial processes involving extremely low temperatures.

Main Features of Cryogenic Compressors

1. Low-temperature resistant: Constructed with cryogenic alloys, stainless steel, or advanced composite materials, ensuring stable operation at -160°C without embrittlement or material failure.
2. Efficient gas compression: Features optimized design elements such as multi-stage compression, cryogenic sealing, and efficient cooling mechanisms to boost compression efficiency and reduce energy loss.
3. Strong gas tightness: Utilizes specialized low-temperature sealing technology to prevent leakage of cryogenic ethylene, enhancing safety and minimizing gas loss.
4. Adaptable design: Available in reciprocating, screw, or centrifugal types to meet various flow, pressure, and environmental requirements.
5. Intelligent control: Equipped with temperature and pressure sensors plus intelligent monitoring systems for safe operation, remote monitoring, and fault alerts.

Working Principle of Cryogenic Compressor

1. Low-temperature gas intake: Ethylene gas at temperatures as low as -160°C enters the compressor through the suction line.
2. Gas pressurization:
   • Reciprocating compressors use pistons for multi-stage pressurization inside the cylinder.
   • Screw compressors compress gas via meshing rotors for continuous and stable delivery.
   • Centrifugal compressors utilize high-speed impellers to convert kinetic energy into gas pressure.
3. Temperature control and cooling: Integrated cooling systems (e.g., deep-cooling heat exchangers, coolant circulation) manage rising temperatures during compression, preventing unwanted phase changes or thermal expansion.
4. Compressed gas output: The pressurized ethylene is delivered to downstream processes such as chemical production, liquefaction plants, or storage systems.

Application Areas of Cryogenic Compressors

1. Ethylene industry: Essential for the storage, transportation, and recovery of cryogenic ethylene in petrochemical processes.
2. Petrochemical and chemical industries: Used in ethylene cracking, cryogenic gas separation, and cooling to enhance ethylene transportation efficiency.
3. Deep-cooling gas engineering: Suitable for LNG, liquid hydrogen, and liquid helium, supporting stable pressurization and delivery at low temperatures.
4. High-efficiency energy systems: Maintains pressure balance in hydrogen, LNG, ethylene, and other cryogenic storage and transportation systems, maximizing energy utilization.
5. Scientific research and aerospace technology: Provides deep-cooled gas supply and efficient pressurization for cryogenic labs, superconducting magnet cooling, and aerospace propulsion systems.
