微萃取-聚结分离技术在碳四脱甲醇中的应用
Removal of methanol in carbon four by microextraction-colescence separation technology
摘要
Abstract
To solve the limitations of methanol washing tower efficiency and the problem of excessive amounts of methanol content in the mixed carbon four in a mixed carbon four deep processing project in a petrochemical company,a complete sets of technical equipment of a hybrid micro extraction coupled modular depth of coalescence separation is developed for removal of methanol in the carbon four. The pilot test is performed at a side line of the petrochemical company. The experimental results show that at the inlet and outlet pressure drop of 5kPa,water injection 5%,retention time within 180s and the inlet methanol content of 300—400μL/L,1200—1400μL/L and 40000—50000μL/L in the mixed carbon four,the outlet methanol content is 10—30μL/L,50—100μL/L and 4000—5000μL/L with a separation efficiency higher than 96%,95% and 88%,respectively. The features of deep and quick separation ability of methanol with low pressure drop at a wider range of elasticity of operation show that the technology has a good applicability in the system of water elution of methanol in carbon four,providing a new way of separating the mixed carbon four and methanol.关键词
