The basis of the equipment based on two main features: the nature of the process, occurring chemical equipment, and the common structural forms, materials, engineering technology. These major characteristics range of chemical equipment is divided into 15 major groups, each of which is divided into types and sizes.

Typical technological process is called the process of manufacture of groups of products with common technological and constructive characteristics. Developing it for production in specific production conditions of the product, which is a typical representative of this group of products. The model is considered representative of the product, the production of which requires the greatest number of basic and auxiliary operations, typical for the manufacture of products of this group.

Grouping products (equipment) on original constructive and technological characteristics is a prerequisite typing of technological processes, contributing to the implementation of the most advanced forms of production. Inosnovannoe on scientific and technical achievements in the field of technology the use of standard processes reduces the time of the industrial development of new products, allows the efficient use of material and human resources, and create a data Bank, includes source information for design of standard chemical engineering processes and equipment.
