Abstract: During the operation of methanol to olefin process,the product gas contains a small amount of byproduct oil-type substances that condenses and deposits together with fine powder in the circulation of water system,which leads to fouling and clogging in the sewage stripping tower tray and reboiler,causes pressure difference in the sewage stripping tower to increase,results in larger fluctuation for system and reaction feed,and causes COD value in purified water to exceed the standard.Solutions for these problems are studied by means of technical transformation and chemical scrubbing.
