Reducing the energy consumption for the own needs of energy sources is an urgent task that can be solved by organizing our own energy sources by using the potential energy of water vapor in steam screw machines. The article discusses some options for installing steam screw machines at the facilities of generating companies and identifies factors affecting the return on steam screw machines in the current operating conditions.

The solution to the issues of increasing energy efficiency and optimizing the work of enterprises in the petrochemical industry is due to the constant increase in prices for primary energy resources. In this article, the technological site for the production of ethylene oxide, which is characterized by high energy intensity, is considered as an object of study. The largest consumer of energy in this area are technologically furnaces. In the framework of the study, an analysis of the operation of the furnaces was carried out, a balance of the heat-technological flows of the site was compiled, the potential for energy conservation in the utilization of the exhaust gases of the process furnaces was calculated, and the possibility of the beneficial use of the obtained heat was calculated. The economic efficiency and payback period of the proposed method of utilization of flue gases is determined.

One of the most common energy carriers in the petrochemical industry is water vapor, which is mainly used as a heating medium in process plants. The effective functioning of steam supply, condensate collection and return systems is one of the criteria that affect the cost of production. Improper organization of the steam supply system leads to overuse of heating steam, uneven operation of the steam system and emergency situations. This paper analyzes possible problems in steam supply systems in the absence or incorrect operation of steam traps. The specific indicators of the object of study, circuit solutions and the economic efficiency of the use of steam traps are calculated.

A priority task for the development of the energy industry is the replacement of the spent estimated lifetime of the generating equipment by new capacities taking into account progressive technologies. Nowadays, combined cycle technology shows itself to good advantage and provides excellent efficiency for any competing gas turbine systems that are likely to be available for large-scale electricity and heat production. In this article the possibility of modernization of the SDPS by building the combined cycle plant is considered.
