Abstract: The presently disclosed subject matter relates to methods and systems for purifying 1,3-butadiene from a C4 hydrocarbon stream. An example method includes introducing a C4 hydrocarbon stream including 1,3-butadiene and acetlyenes to an organic azide in the presence of a catalyst to generate a first stream including triazole, separating triazole from the first stream to produce a second stream including 1,3-butadiene, and distilling 1,3-butadiene from the second stream to produce a purified 1,3-butadiene product stream.

Abstract: The present invention provides, among other things, new processes for separating and purifying C4 fractions from a crude C4 stream. Compared to prior methods, the processes of the present invention simplify the C4 separation processes, afford more possible configurations for separation and purification, and are more cost effective. The processes and systems provided herein can be used as part of a cost-effective and efficient method for synthesizing methyl tertiary-butyl ether.
Abstract translation: 本发明尤其提供了从粗C4流分离和纯化C4级分的新方法。 与现有方法相比，本发明的方法简化了C4分离过程，提供了更多可能的分离和纯化配置，并且更具成本效益。 本文提供的方法和系统可以用作合成甲基叔丁基醚的成本有效和有效方法的一部分。
