### Abstract

The paper presents a method to improve the speed of modeling in the MARS modeling framework. The framework allows for flexible modeling of complex processes of chemical industry by representation of industrial apparatuses as sets of primitives in a component circuit. Typical abstract primitives used in modeling of chemical process systems are analyzed: source, mixer, and separator. They are found to often contain variables whose value may be determined separately with less computational load com-pared to their inclusion into the general system of linear and linearized equations. An algorithm for formation of a shortened system of equations and independent solution of easily solvable equations is presented.
