Application of Artificial Intelligence in the Process of Adsorption Purification of Isobutane, Isobutylene and Benzene from Impurities

Abstract:

The article is devoted to mathematical modeling and fuzzy logic in controlling the process of adsorption purification of isobutane and isobutylene from impurities. The article also conducted research on the production of high-purity isobutane and isobutylene from the isobutane-isobutylene fraction of pyrolysis gas. A method has been developed for increasing the purity of isobutane and isobutylene fractions isolated from pyrolysis gas using sulfuric acid. It is proposed to introduce adsorption units into the plant technological scheme for separating the hydrocarbons isobutane and isobutylene from the C4 fraction of pyrogas, with the help of which it has been proven to obtain isobutane and isobutylene hydrocarbons of high purity up to 99.9%. The processes of selecting adsorbents for the additional purification of the isobutane fraction from isobutylene impurities were also studied and activated carbon of the AP-3 grade was selected, and for the additional purification of the isobutylene fraction from impurities of normal butylene’s, CaA zeolite was selected. The main reactions have been studied and a mathematical model of the processes for producing pure isobutylene and isobutane has been developed, taking into account recycling; also, artificial intelligence (AI) has been used when selecting adsorbents to optimize the processes of purifying the pyrolysis gas fraction of isobutane and isobutylene from impurities.
