摘要

天然气的预处理和液化是海上天然气利用前的两个关键环节。选取变压吸附分离法(PSA)作为浮式LNG预处理流程的工艺方法

选择新型CO2预冷空气膨胀液化流程作为浮式LNG天然气液化的工艺方法

并对以上预处理和液化流程进行了模拟计算与分析。结果表明

采用双层吸附剂变压吸附(PSA)预处理流程能耗低

全气体运行避免了液体吸收剂随波浪晃动的缺点

可以满足海上天然气预处理的要求;CO2预冷空气膨胀液化流程在预冷剂及制冷剂循环过程中

没有液体的产生

安全性高;以上预处理和液化流程适应于海上晃动的LNG平台。

Abstract

Pretreatment and liquefaction of natural gas are two key links of offshore LNG-FPSO.The pressure swing adsorption(PSA)as natural gas purification and CO2 pre-cooling air expander cycle as natural gas liquefaction are selected and simulated and analyzed.The results show that

the energy consumption of the double layers adsorbents PSA is low

and the disadvantage of liquid absorbent with the wave shaking can be avoided by the process operation of the gas; and there is no liquid produced in the precooling and refrigeration processes of the CO2 pre-cooling air expander cycle

indicating its high safety; the above purification and liquefaction processes are suitable for offshore LNG platforms.
