摘要
脱除酸性气体的ＨＳ净化技术，是在碳酸丙烯酯溶剂中加入特殊的添加剂而实现的。工业应用表明，它可以在不改变原工艺条件及设备的情况下，使脱硫效率提高数十倍，脱碳能力提高２０％，溶剂蒸汽压降低５０％左右。
The HS purification process is carried out using a specific kind of additive add in propy-lene carbonate(PC)solvent.As the industrial application showed,in same conditions and equipments as the originaI PC process,the removal efficiency increased by tens times for H_2S and 20%for CO_2 respec-tively. The vapour pressure of the solvent is 50%lower than PC solvent.
