摘要
用新开发的ＤＨＸ模拟软件对ＤＨＸ工艺进行全流程模拟，并与ＩＳＳ工艺进行对比分析，研究ＤＨＸ工艺对原料的适应性，考察原料气中Ｃ１／Ｃ２比值和Ｃ３＋含量对Ｃ３回收率的影响．结果表明，ＤＨＸ工艺Ｃ３回收率提高的幅度主要取决于原料气中心Ｃ１／Ｃ２比值，而原料气中Ｃ３＋含量对此影响较小．ＤＨＸ工艺的应用受原料气组成的限制．
The full pan of DHX is simulated by newly developed software system of DHX and com- pared with the conventional process of ISS. The adaptability of DHX to the gas feed was studied. The effect of C1/C2 ratio and the content of C3+ on recovery rate of C3 was inustigated.The result shows thatthe increasing of recovery rate of C3 depends mainly on the C1/C2 ratio in the gas feed, and the influence of C3+ content in the gas feed on recovery rate of C3 is smaller. The application of DHX process is re- stricted by the composition of the gas feed.
