SC catalytic treatment plant (basic module)

SC catalytic treatment plant with rotary concentrator. Purpose:

• Purification of gas emissions from technological lines in chemical, petrochemical and woodworking industries
• Purification of tanks’ and reservoir parks’ big breath (evaporation)
• Neutralization of emissions during loading / unloading of oil products from tankers; storage and transshipment of hydrocarbons at distribution depots, etc.

SC catalytic treatment plant is used for purification of industrial emissions from contaminants:

• carbon monoxide (CO)
• Volatile Organic Compounds (VOCs)
• benzene, toluene, xylene, phenol, formaldehyde, methanol, butyl acetate, acetone, acetic acid, styrene and other saturated, unsaturated, cyclic, aromatic hydrocarbons and their derivatives (alcohols, aldehydes, ketones, etc.)
• chloromethane, chlorobenzene, methyl chloride and other organic compounds.

For the optimal selection of the required SC plan module, use the Table of the main sources of industrial emissions.

Technological process:

STAGE 1. Mixer. Getting a gas-air mixture, lowering the concentration of hydrocarbons.

Contaminated gases are directed by gas blower (1) to the mixer (2), where they are mixed with air.

The air through the air filter (3) is directed by the fan (4) to the mixer (2).

The resulting gas-air mixture is fed into the afterburner.

STAGE 2. Afterburner. Catalytic neutralization.

The prepared gas-air mixture is fed into the shell of the vertical shell-and-tube heat exchanger* (5), where it is heated by the heat of the purified stream exiting the catalytic unit through HX tubes.

• The catalytic unit (6) is preheated by heating elements (7) to the process activation temperature.
• After the Unit enters operational mode, the heating elements are switched off. The working temperature of the incoming stream is ensured by the recovery of heat from the exhaust gases.
• The process of oxidation of organic substances to harmless carbon dioxide and water is carried out on a platinum catalyst (6).
• The neutralized gases are cooled in the recovery boiler by the incoming stream and then discharged into the atmosphere.
• Emissions to the atmosphere are reduced to the minimum values.

Feature of the basic module of the SC plant:

To meet the requirements of the energy recovery process in recovery boiler, contaminated gases must be diluted with air.

*The type of heat exchanger depends on the unit’s construction

*without taking into account exhaust pipe height
