摘　　要：针对原油储罐区域的特殊工况选择适合的干法吸附脱硫工艺,确定应用氧化铁脱硫剂和活性炭脱硫剂吸附法,并用市售脱硫产品进行实验室小试;同时,进行了原油储罐区现场实验。发现现场实验硫容较实验室硫容有所减小,分析原因是由于油罐挥发气成分比较复杂,吸附剂除对H2S进行吸附外,对硫醇、甲苯等也有吸附作用。The dry adsorptive desulfurization was adopted according to the working condition of dispersed crude oil storage tanks.Ferric oxide and activated carbon were chosen as adsorbents,and three commercial adsorbents were tested in laboratory.Meanwhile,the on-site desulfurization experiment of crude oil storage tank was also performed.It shows that compared with the adsorption capacity of H2S obtained in laboratory,the capacity of which obtained in the on-site experiment decreases.The reason is that volatile gas composition of crude oil is more complex.Besides adsorbing H2S,the adsorption agent also has adsorption effect on mercaptan,toluene,etc.
