丁烯提浓技术简介

Brief Introduction of BUTENEX

丁烯提浓技术（BUTENEX）是当今世界上用来分离C4馏分中正丁烯与丁烷组分最先进的萃取精镏技术，利用吗啉和N－甲酰吗啉混合物做为萃取剂，采用Sulzer（苏尔寿）高效填料。正丁烯产品纯度高（≥97％），且产品中萃取剂含量极低（≤0．0001％）。该技术在化工分离中应用的潜力很大。

BUTENEX is the most advanced extractive distillation technology for N-butene and butene separation up to now, uses morpholine and n-formyl morpholine for extraction solvent,adapts Sulzer efficient packing. N-butene product purity is high(≥97%), and extraction solvent content in N-butene is very low(≤0. 0001 %). BUTENEX has a hopeful development prospect in chemical separation.
