UNIT OPERATIONS IN CHEMICAL INDUSTRIES

Abstract

The unit operation like distillation, absorption, evaporation, filtration, drying, etc. are most important factors. Distillation is a purification method for liquids and can separate components of a mixture if they have significantly different boiling points. Absorption is a physical or chemical phenomenon. Evaporation can be defined as the process where liquid is transformed into a gaseous state. Evaporation can occur only when water is available. Drying is an important unit operation in a type of chemical process industries (CPI) sectors. Food, pharmaceuticals, chemicals, plastics, timber, paper and other industries use drying equipment to eliminate moisture during product processing. Keywords: Distillation, Absorption, Evaporation, Filtration, Drying.
