Document Type and Number:
WIPO Patent Application WO/2018/018651
Kind Code:
A1
Abstract:
Provided are a method and system for separating a t-butanol and diisobutylene azeotrope. The purpose of separating t-butanol from diisobutylene is achieved by allowing the selective adsorption of t-butanol with an adsorbing agent flowing together with t-butanol and diisobutylene in a suspended bed, and performing continuous separation of diisobutylene from the adsorbing agent and continuous regeneration of the adsorbing agent using devices such as a separator and an injector. In the method, no extraction agent is introduced, no large-scale, high-pressure equipment is used, the operating conditions are mild, the energy consumption is low and the safety risk is low.
