English: The monograph examines the theoretical problems of chemical technology processes that have historically developed through the creation of building materials, metallurgy, the production of inorganic and organic compounds, as well as the processing of agricultural products into food products. Widely using mathematical methods of modeling, the method of theoretical generalizations, the graph method, the authors give new systems of equations of statistics and kinetics of processes. The problems of theory and calculation methods for chemical reactors are discussed, which are considered the basis of the "processor unit" in technological production, and also the problems of intensification and optimization of chemical-technological processes are considered.
