Abstract

The increase in the cost of fuel and energy resources motivates industrial enterprises to introduce new technical solutions for their effective use. At the same time, as a result of the production ac-tivities of industrial enterprises, a significant amount of waste is generated that negatively affect human health and the environment. Such enterprises include caustic soda production plants, the technology of which is associated with the formation of thermal and combustible secondary energy resources in the form of steam, condensate, process water, etc. Such types of resources may be useful to use for the production of thermal energy for the company's own needs, or heating of raw materials or material flows involved in the technological chain. The technology of caustic soda production is considered it this paper, the basic structure of production is discussed, the material balance is given, options for improving the efficiency of energy resources are proposed.
