What are the large equipment in chemical factories?

The common large-scale equipment in chemical factories includes tower equipment, reactors, industrial furnaces, flare chimneys, heat exchangers, and pumps. These devices play a crucial role in the production process of chemical factories.
tower
Tower equipment is one of the most common equipment in petrochemical production facilities, mainly used for sufficient contact, separation, mass transfer, and heat transfer of gas-liquid media, thereby achieving the exchange of mass and heat. Common tower equipment includes:
Packing tower: The interior is filled with packing material to increase the gas-liquid contact area.
Plate tower: gas-liquid separation and mass transfer are achieved through trays.
Spray tower: used for gas purification and recycling.
reactor
A reactor is equipment used for chemical reactions in chemical production, and common types include:
Fixed bed reactor: The catalyst is fixed inside the reactor and is suitable for catalytic reactions.
Tube reactor: The reactants flow inside the tube and are suitable for reactions that require high temperature control.
Fluidized bed reactor: Solid particles are in a fluidized state in the fluid, suitable for large-scale production.
Industrial furnace
Industrial furnaces are used for heating and processing materials, and common types include:
Box furnace: suitable for heating large-sized materials.
Cylindrical furnace: suitable for continuous heating treatment.
flare stack
Torch chimneys are used to discharge exhaust gases, and common types include:
Chimney: used for discharging exhaust gases.
Torch: Used for emergency discharge or combustion of excess gases.
heat exchanger
Heat exchangers are used for heat exchange, and common types include:
Fixed tube plate tube heat exchanger: with a simple structure, suitable for medium and low pressures.
U-shaped tube heat exchanger: suitable for high temperature and high pressure environments.
Floating head tube heat exchanger: suitable for occasions where tube bundles need to be cleaned.
pump
Pumps are used in chemical factories to transport liquids, and common types include:
Centrifugal pump: suitable for conveying clean liquids.
Water ring vacuum pump: used to generate vacuum.
Gear pump: suitable for conveying high viscosity liquids.
