description: The work is devoted to the study of the possibility of applying heat treatment using a steam screw machine in OOO Mednogorskij medno-sernyj kombinat. To assess the energy saving potential, an analysis of the existing steam supply system at the plant, as well as evaporative cooling systems of metallurgical equipment, was carried out. The possibility of useful use of the energy of the steam pressure drop between the collector from the separator drums and the steam network of the combine has been revealed. Four variants of the integration scheme of a steam screw machine for generating electricity for the plants own needs have been developed. After the thermal calculations, it was revealed that out of the 4 options considered, option 2 is the only suitable option. The main and auxiliary equipment were selected for the selected option. The economic efficiency of two variants of the project implementation was also evaluated at the expense of the companys own funds and at the expense of a loan, calculations were carried out in the Alt-Invest program.
