The aim of this paper work is to study the model of the process of sulphuric-acid alkylation of isobutane using a mathematical model. The model of the object was developed considering the physicochemical regularities of the process. The paper analyzes the main processes occurring at the installation and performs the results of model verification. In addition, the technological scheme of one of the sulphuric-acid alkylation existing installations were considered. The developed program is able to calculate the composition of the obtained alkylate, to determine the yield of target products and by-products, to select optimal technological process conditions for a given raw material composition. It was noted, that the consumption of sulfuric acid increases as a result of the accumulation of high-molecular organic compounds in it, as well as its dilution with water, which enters the reactor along with the raw material and forms during the side reactions of the process.
