摘要
用于长庆苏里格气田天然气低温流程的气 气冷换器的结构型式为重叠式 ,由球型封头、管程筒体和法兰、壳程筒体和法兰、管板、折流板、换热器等组成。设计中 ,法兰的优化结果比标准法兰质量轻 4 8%～ 5 8% ;大直径缠绕垫片突破了国内 10MPa的压力限制 ;整个设备设计开创了国内冷换器试验压差 2 0MPa、工作压差 16 1MPa的设计先河。 2年多的现场运行试验表明 ,这种冷换器运行安全可靠 ,实现了预期的工艺目标 ,保证了西气东输的按时实现。
The gas-gas heat exchanger is developed specially for natural gas processing at low temperature in Changqing Sulige gasfield. This equipment is designed as overlapped tube array for heat exchange. The structure and operating principle of the heat exchanger are described. The size and structure of its flange are designed more reasonable than what the Chinese industrial standard stipulated, and the spiral wound gaskets are applied under the condition of working pressure of over 10 MPa. And the whole equipment is designed and manufactured with a test differential pressure of 20 MPa and operating differential pressure of 16.1 MPa. On-site operation test for 2 years showed that this heat exchanger ran reliably and safely.
