摘要
针对甲醇制烯烃(MTO)装置急冷水系统运行的瓶颈问题,以某年处理 180 万t甲醇的MTO装置为研究对象,结合装置近三年运行数据,分析了急冷水系统固含量高的原因,并对瓶颈问题进行了定性、定量分析.通过试用急冷水高温萃取剂、采用分离技术、耦合沉降罐与地下污水池技术、应用沸腾床过滤技术,使急冷水含固质量浓度降至 1 000 mg/L,实现了急冷水系统平稳运行.
Abstract
Aiming to address the bottleneck issue in the operation of the quench water system in a methanol to olefin(MTO)plant,taking one MTO plant with an annual methanol treatment capacity of 1.8 million tons as the research object,combined with relevant operating data of the plant in the past three years,the causes of high solid content in the quench water system were analyzed,and qualitative and quantitative analysis on the bottleneck problems was conducted.By trial use of high temperature crude extractant for quench water,using separation technology,coupling settling tank with underground sewage tank and applying fluidized bed filtration technology,the mass concentration of solids in quench water reduced to 1 000 mg/L,achieving stable operation of the quench water system.
