摘要
甲基叔丁基醚(MTBE)为高辛烷值清洁汽油的重要调和组分,对其进行深度脱硫使其硫质量分数低于10μg/g,是炼化企业亟待解决的问题。对MTBE产品硫质量分数偏高的原因进行了分析,鉴于MTBE原料脱硫存在苛刻度大、波动较大的特点,采用MTBE产品脱硫更稳定可靠。对目前工业化的吸附脱硫、萃取脱硫、络合脱硫技术进行了技术经济分析,针对企业MTBE装置深度脱硫改造空间小的现状,考虑选择萃取脱硫或络合脱硫技术进行深度脱硫。
Methyl Tert- butyl Ether（ MTBE） is an important blending component for high- octane clean gasoline,so deep desulfurization to make the mass fraction of sulfur in MTBE below 10 μg / g is an urgent problem for enterprises to solve. The causes of high sulfur content in MTBE products were analyzed. In view of the high severity and high fluctuation characteristics of MTBE material desulfurization,MTBE feedstock desulfurization was considered to be more stable and reliable. Based on techno- economic analysis of the industrialized desulfurization technologies as adsorption desulfurization,extraction desulphurization,and complexion desulphurization,considering the current status of little space for deep desulfurization transformation of MTBE plant in the Company,extraction desulphurization and complexion desulphurization technologies were recommended for deep desulfurization.
