摘　　要：研究了固定床吸附法脱除CO_(2)技术在甲醇制烯烃(MTO)装置中的应用,并采用该技术对国能榆林化工有限公司的湿法碱洗技术进行工艺替换,满足了装置对CO_(2)的脱除要求,同时实现了节能减排的目的。工业应用数据表明,固定床吸附法脱除CO_(2)技术可将MTO产品气中的CO_(2)((100~400)×10^(-6)(φ))脱至1×10^(-6)(φ)以下,且能得到纯度不低于99.6%的聚合级乙烯产品,产品C_(3),C_(4)质量均满足技术要求。The application of fixed bed adsorption technology for CO_(2)removal in methanol to olefins(MTO)product gas was studied.The technology was used to replace the original wet alkali washing technology of National Energy Group Yulin Chemical Co.,Ltd.,which met the requirement of CO_(2)removal and realized the purpose of energy saving and emission reduction.Industrial application data show that the fixed bed adsorption method can remove the CO_(2)((100-400)×10^(-6)(φ))in the MTO product gas and make it less than 1×10^(-6)(φ).Polymerized ethylene products are obtained with a purity of no less than 99.6%,and the quality of both C_(3)and C_(4)products meets the technical requirements.
