Question

What is difference between between unit process and unit operations?

Answer 1

In unit operations thier is only physical change is occur but no chemical change take place or we can say no chemical reaction take place. Evaporation, Distillation, Liquid liquid extraction, Drying, Size reduction, Crystallization are the example of unit operations.
A ''unit process'' is one or more grouped operations in a manufacturing system that can be defined and separated from others. In life-cycle assessment and ISO 14040, a unit process is defined as "smallest element considered in the life cycle inventory analysis for which input and output data are quantified".
