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,Alkylation,Dealkylation,Esterification,Polymerization,Polycondensation,Catalyze

Oxidation describes the loss of electrons / hydrogen or gain of oxygen / increase in oxidation state by a molecule, atom or ion.
Reduction describes the gain of electrons / hydrogen or a loss of oxygen / decrease in oxidation state by a molecule, atom or ion.
Hydrogenation is the chemical reaction that results from the addition of hydrogen (H2). The process is usually employed to reduce or saturate organic compounds.
Dehydrogenation is a chemical reaction that involves the elimination of hydrogen (H2). It is the reverse process of hydrogenation. Dehydrogenation reactions may be either large scale industrial processes or smaller scale laboratory procedures.
Hydrolysis is a chemical reaction during which one or more water molecules are split into hydrogen and hydroxide ions, which may go on to participate in further reactions.[1][2] It is the type of reaction that is used to break down certain polymers, especially those made by step-growth polymerization.
Hydration may refer to:
Hydration reaction, a chemical addition reaction where a hydroxyl group and proton are added to a compound
Mineral hydration, an inorganic chemical reaction where water is added to the crystal structure of a mineral
Solvation, the clustering of solvent (water) molecules around a solute particle

Dehydration (hypohydration) is defined as excessive loss of body water.[1] It is literally the removal of water (Ancient Greek: ?d??, hýdor) from an object. In physiological terms, it entails a relative deficiency of water molecules in relation to other dissolved solutes. Some definitions even require a rise in blood sodium concentration[2], but in reality a loss of body water usually accompanies a loss of solutes as well.

Halogenation is a chemical reaction that incorporates a halogen atom into a molecule. More specific descriptions exist that specify the type of halogen: fluorination, chlorination, bromination, and iodination
Nitrification is the biological oxidation of ammonia with oxygen into nitrite followed by the oxidation of these nitrites into nitrates. Degradation of ammonia to nitrite is usually the rate limiting step of nitrification. Nitrification is an important step in the nitrogen cycle in soil

Alkylation is the transfer of an alkyl group from one molecule to another

Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product

In polymer chemistry, polymerization is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.[1][2][3] There are many forms of polymerization and different systems exist to categorize them.

Catalysis is the process in which the rate of a chemical reaction is either increased or decreased by means of a chemical substance known as a catalyst.
in this manner unitprecesses play an important role in almost all the industrial applications
