On the basis of mathematical modeling method and physical-chemical nature of gas from liquid hydrocarbons and water at low temperatures due to the Joule-Thompson effect separation, a mathematical model of separator was created. This model allows tracing changes in technological parameters of low temperature separation process in real time. It is implemented as a software product that allows one to study transient processes occurring in apparatus of chemical technological system and also provides an opportunity to examine the effect of control parameters on technological parameters of the system. It was shown that the opening degree of gas valve is gradually reduced (from 28% to 10% in 40 seconds) while pressure in system increases from 7,082 MPa up to 7,633 MPa. On the basis of developed mathematical model a simulator for training of technical personnel of low-temperature separation can be created.
