甲基叔丁基醚生产深度脱硫工艺的选择
Choice of MTBE deep desulfurization process
摘要
Abstract
The control index of sulfides content in gasoline additive MTBE was introduced based on the National 5th Stage Motor Vehicle Gasoline Standard. A new algorithm for enrichment coefficient calculation was given based on the analysis of sulfides composition, sources and enrichment effect in MTBE. The results showed that enrichment coefficient was up to 4.44 at ethylene content in LPG between 15%~30%by weight. The analysis of other influencing factors showed that enrichment effect was the most important factor. As the investigation of MTBE desulfurization process by distillation and LPG fine desulfurization process demonstrated that two-column MTBE desulfurization process by distillation was more suitable in new gasoline additive production,considering its relatively low invest cost,energy cost and use of adsorbent,and the sulfides content in MTBE can be controlled under 3mg/kg.关键词
