Mathematical study of low-temperature natural gas separation process

The main focus of this study is the procedure for separating natural gas at low temperatures. The system consists of three heat exchangers and three stages for reducing gas. The composition and purpose of the correction column are explained. The study demonstrates how various parameters, with pressure being the most important, affect the rectification process. Additionally, the study explains how the inhibitor regeneration mechanism works. The system involves interconnected mass and heat exchange processes within the "Rectification" subsystem, which can be described by a dynamic nonlinear mathematical model.Additionally, the system also includes a nonlinear discrete-continuous model. The transient processes of mass and heat exchange are obtained and studied based on the discrete-continuous model, using the specified initial and boundary conditions.
