What is different between unit operation and unit process
Answers
Answer:
Hey mate there is your answer.
TO CONVERT RAW MATERIALS INTO PRODUCTS THERE ARE TWO PROCESSES INVOLVED, UNIT OPERATIONS AND UNIT PROCESSES.
Unit Process:- It involves the conversion of raw material into product chemically(by chemical reaction) means your raw material which had some chemical compound is changed to your product which has different chemical compound.
Unit Operation are processes related to physical changes of the materials involved:
- Mixing (Solid-Solid, Solid- Liquid, Solid-Gas, Liquid-Liquid, Liquid- gas, Gas-Gas)
- Separating (Sieving, Filtration, Distillation, Fractional crystallization, Fractional freezing, Centrifugation)
- Heating/Cooling of materials
- Transporting (Solid, Granulates, Liquids, Slurries, Pastes)
- Measuring (weighing, Volumetrizing, Counting)
Unit Operations:- It involves the separation (by means of heat transfer, mass transfer, solubility, barrier) transportation, mixing, blending, size reduction of components only physically(no chemical reaction). Unit operation can be used before and after unit process according to the desired property of the raw material and product.
Unit Processes are those related to chemical changes of the materials involved:
- Neutralization
- Oxidation
- Nitration
- Polymerization
- Diazotization
- Chlorination
- Alcylation
