Abstract

Results of the development of theoretical fundamentals of the production of high-purity isobutane and isobutylene from isobutane–isobutylene fraction of pyrolysis gas are given. The experimental part includes the method for increasing the purity of isobutane and isobutylene fractions isolated with the help of sulfuric acid from isobutane–isobutylene fraction of pyrolysis gas. It is proposed to add two adsorption blocks into industrial technological schemes for the isolation of isobutane and isobutylene from the С₄ fraction of pyrolysis gas. A mathematical model of processes for the production of high-purity isobutane and isobutylene taking into account principles of the recirculation theory is developed.

在带再循环模块的工程系统中生产高纯度异丁烷和异丁烯

摘要

给出了从热解气中的异丁烷-异丁烯馏分生产高纯度异丁烷和异丁烯的理论基础的发展结果。实验部分包括增加从热解气中异丁烷-异丁烯馏分中分离出的硫酸的方法，以提高异丁烷和异丁烯馏分的纯度的方法。它建议增加两个吸附块分成工业技术方案为异丁烷和异丁烯的从С隔离₄的热解气体的一小部分。考虑到再循环理论的原理，建立了生产高纯度异丁烷和异丁烯的过程的数学模型。
