摘　　要：主机透平的燃料气需要一定的过热度。常规的直接加热法燃料气处理工艺,通过提高供气温度达到过热度要求,能耗较高,且可能存在供气温度过高,无法满足用户需求。当燃料气系统有较大压差可供利用时,采用低温分离法,利用焦汤效应进行低温分离,降低燃料气的露点,再通过高/低温燃气换热进行能量回收,达到过热度的要求,解决燃气温度过高问题的同时,可以降低热负荷,产生可观的经济和社会效益。The main engine gas tubing needs a certain degree of fuel gas superheat.The direct heating treatment process can meet the superheat by increasing the gas supply temperature.But this process with high energy consumption,and the gas supply temperature may exceed the max.design temperature of the gas tubing.When high pressure drop is available,the low-temperature separation method using J-T effect archive a low-temperature to reduce the dew point of fuel gas is adopted,a heat exchangeand will be installed to recover energy.Low temperature separation method can greatly reduce the heating load and produce considerable economic and social benefits.
