Mathematical Modeling of Plants for the Combined Production of Liquid Hydrocarbons and Electricity Based on Coal

Abstract—Various aspects of the synthesis of gasoline fraction hydrocarbons from methanol obtained at power-engineering plants for the synthesis of methanol from coal are considered. The methods and approaches used in the modeling of hydrocarbon synthesis processes based on the principles of equilibrium thermodynamics and phase separation processes of multifraction mixtures are substantiated and described. Conditions for combining a hydrocarbon synthesis unit with power-engineering plants for the synthesis of methanol from coal are considered. Based on the results of studies of the unit for the synthesis of hydrocarbons from methanol, including detailed material and thermal balances, the economic efficiency conditions of the conversion of methanol produced from coal into liquid hydrocarbons at a single plant are estimated.
