EAC-6型硫醇精脱硫剂的开发及其工业应用

介绍了对华烁科技股份有限公司研制的EAC-6型硫醇精脱硫剂的实验评价。结果表明,EAC-6精脱硫剂对硫醇有优异脱除性能。实验考察了水汽和温度对硫醇硫容的影响。在进口φ(CH3SH)为0.5%的干气中,空速1000h-1,30℃～90℃时,出口φ(CH3SH)≤0.03×10-6,工作硫容可达7%～10%。工业应用表明,EAC-6型硫醇精脱硫剂出口各种形态硫醇的体积分数均≤0.03×10-6,很好地保护了下游的甲醇合成等的高效催化剂。

Development of mercaptan removal fine desulfurizer EAC-6 and its industrial application

The experimental evaluation of mercaptan removal fine desulfurizer EAC-6 developed by Haiso Technology Co.was presented The results showed EAC-6 had excellent performances on mercaptan removal.Effects of water vapor and temperature on the sulfur capacity of EAC-6 were investigated.Under the conditions of dried feed gas with mercaptan volume fraction of 0.5%,space velocity of 1000 h-1 and temperature of 30-90℃,the outlet mercaptan volume fraction could be reduced to less than 0.03×10-6,and the sulfur capacity of EAC-6 reached 7% to 10%.The industrial application results showed that the volume fraction of each of all mercaptans in various forms in the feed gas was reduced to less than 0.03×10-6 after treated by EAC-6,which effectively protected the follow catalysts,such as the catalyst for methanol synthesis.
