Evaporation of citric acid – design of a vacuum evaporator

The evaporator is an important piece of equipment for many enterprises in the chemical, food and other industries. Evaporation is used in factories of mineral salts, nitrogen fertilizers, soda, chlorine, sugar, starch plants, in the aluminum, pulp and paper industries and in the production of polymeric materials. In the chemical industry, solutions of solids (solutions of alkalis, salts), as well as solutions of high-boiling liquids, which at the evaporation temperature have a very low vapor pressure, that is, almost non-volatile (these include some mineral and organic acids (among which is itaconic acid), polyhydric alcohols, etc.) Description of the technological process, purpose and scope of use of the installation, technical characteristics, justification of the choice of the chosen design, calculations confirming the operability and reliability of the design, recommendations for installation and operation. Instrumental and technological scheme of the citric acid production line A1); vertical leather-chopping heat exchanger. In this archive there is a course project, a drawing of a vacuum evaporation apparatus, an equipment diagram (technological scheme) for the production of acid, a specification.
