In manufacturing, a unit process is single component part of the end-to-end manufacturing process that transforms raw materials into finished goods.

[edit] Unit processing in chemical engineering

Unit processing is the basic processing in chemical engineering. Together with unit operations it forms the main principle of the varied chemical industries. Each genre of unit processing follows the same chemical law much as each genre of unit operations follows the same physical law.

Chemical engineering unit processing consists of the following important processes:

• Oxidation
• Reduction
• Hydrogenation
• Dehydrogenation
• Hydrolysis
• Hydration
• Dehydration
• Halogenation
• Nitrification
• Sulfonation
• Ammoniation
• Alkaline fusion
• Alkylation
• Dealkylation
• Esterification
• Polymerization
• Polycondensation
• Catalyze
