Abstract

The aim of the present paper is to increase the efficiency of low-temperature gas separation plant with use of simulation dynamic model. The paper analyzes the main processes occurring at the installation and performs the results of model verification. In addition, the technological scheme of natural low-temperature gas separation and operating parameters of one of the existing installations were considered. A non-stationary mathematical model of the chemical-technological system of low-temperature gas separation was developed. Due to the unsteady mathematical model, it became possible to estimate the time spent on the transient phenomena, as well as to choose the rate of low-temperature separation control parameters change, depending on the technological mode. Eventually, the calculations show how it is possible to avoid the instability of plant operation upset conditions at the workplace. The field of the developed model application is oil and gas industry and also higher education institutions. This software can be used to test the stability of both existing and projected low-temperature gas separation plants.
