影响邻二甲苯产品杂质含量的因素分析与优化对策

为了稳产高产邻二甲苯（OX）产品，对影响邻二甲苯产品的杂质间二甲苯（MX）、异丙苯（IPB）含量的因素进行分析，找到了影响产品纯度的关键因素。通过卡边操作、积极探索、优化精馏塔的操作条件，使产品中的间二甲苯、异丙苯这两种杂质含量控制在较低水平，就能保证其他杂质也在较低的水平。从而使得产量得到了最大化，满足了用户的需要，提高了公司经济效益。

For high and stable yield of o-xylene （OX） products, affecting ortho-xylene product impurities meta-xylene （MX）, isopropyl benzene （IPB） levels of factors were analyzed, and found the key factors influencing the purity of the product. Through the card side operation, actively explore and optimize the operation condition of rectification tower, make the product of meta-xylene, isopropyl benzene this two kinds of control in low content of impurities, can guarantee other impurities at the lower level. So as to make the production to get the maximization, meet the needs of the users, improving economic efficiency of the company.
