The chemical industry is developing at a considerably higher rate than other industries. Modern chemical enterprises are intricate combinations of various chemical plants united by the comprehensive utilization of the raw materials or the preparation of various intermediates needed for the production of a commercial product.
In addition to purely chemical enterprises, plants of many other branches of industry are based on chemical technology principles. Numerous productions processed in the metallurgical, pulp and paper, textile, food, refrigerating, pharmaceutical, motion picture industries and photographic are purely chemical ones.
The modern chemical industry together with the related branches of industry manufacture thousands of products, and it is impossible to describe how they are made within the limits of one course. Engineers being trained in the chemical and chemical engineering departments of non-chemical colleges and institutes do not need to study a large numbed of chemical production processes. They only have to know the general laws of chemical technology, the most typical chemical production processed, and the reaction equipment need for them. The application of the general laws to specific chemical processes can be studied by using as examples basic processed that are significant for the national economy and correspond closely to the profile of these departments.
The problems of power engineering and environmental protection have acquired an exclusive importance during recent years. These problems are closely related to chemical technology because many chemical enterprises require a radical reconstruction so that they can fully utilize raw materials, eliminate waste in production processes, utilize the heat of chemical reaction, i.e. covert chemical technology into power technology.
