Hydrogenation is a chemical reaction that adds hydrogen to a molecule. Catalysts like nickel, palladium, and platinum are commonly used. Hydrogen gas is vented through a pressure relief valve (PRV). Vacuum distillation is a process that separates components based on their boiling points under reduced pressure. Cooling tower and chilling plant capacity depends on the specific application.

Unit operations involve physical changes in the material, while unit processes involve chemical changes.
Unit operations involve physical processes like mixing, crushing, distillation, filtration, etc.
Unit processes involve chemical reactions like oxidation, reduction, hydrolysis, etc.
Unit operations are usually used in the initial stages of production, while unit processes are used in the later stages.
Unit operations f...
Types of reactors include batch reactors, continuous stirred-tank reactors, plug flow reactors, and fluidized bed reactors.
Batch reactors: Used for small-scale production and testing.
Continuous stirred-tank reactors: Ideal for continuous production with uniform mixing.
Plug flow reactors: Allow for efficient heat transfer and minimal back-mixing.
Fluidized bed reactors: Suitable for high-temperature reactions and catalys
Types of agitators include paddle agitators, anchor agitators, turbine agitators, and propeller agitators.
Paddle agitators are used for low viscosity fluids and gentle mixing.
Anchor agitators are used for viscous fluids and provide good radial mixing.
Turbine agitators are used for high viscosity fluids and provide high shear mixing.
Propeller agitators are used for low viscosity fluids and provide axial flow mixing.
Gas drying is used to remove moisture from gases, while steam drying is used to remove moisture from solids or liquids.
Gas drying involves passing a gas stream through a desiccant material to remove moisture, commonly used in natural gas processing.
Steam drying involves using steam to evaporate moisture from solids or liquids, commonly used in food processing or paper production.
Gas drying is more suitable for removing...
Heat exchangers are devices used to transfer heat between two or more fluids at different temperatures.
Types of heat exchangers include shell and tube, plate heat exchangers, and finned tube heat exchangers.
Shell and tube heat exchangers consist of a shell with tubes running through it, allowing one fluid to flow through the tubes while another flows over the tubes.
Plate heat exchangers use metal plates to transfer hea...

There are various types of reactors used in production processes, such as batch reactors, continuous stirred-tank reactors, and plug flow reactors.
Batch reactors are used for small-scale production and allow for easy control of reaction conditions.
Continuous stirred-tank reactors are used for continuous production and have good mixing capabilities.
Plug flow reactors are used for reactions that require a specific reside...
Types of distillation columns include batch, continuous, fractional, and steam distillation.
Batch distillation: Used for small-scale production and involves separating components based on boiling points.
Continuous distillation: Used for large-scale production and involves a continuous feed of mixture and product removal.
Fractional distillation: Used to separate components with closer boiling points by creating multiple...

Sulfuric acid is produced through the contact process, involving the oxidation of sulfur dioxide to sulfur trioxide, followed by the hydration of sulfur trioxide.
Sulfur dioxide is oxidized to sulfur trioxide using a catalyst such as vanadium pentoxide.
Sulfur trioxide is then hydrated to form sulfuric acid.
The process involves multiple steps and careful control of temperature and pressure.
The contact process is the most...
