How to treat oil refinery exhaust gas

Refinery production process produces acidic waste gas and odourous waste gas, if the waste gas is not properly treated will have a great impact on the surrounding environment and people's work and life, how to deal with the oil refinery waste gas? How to deal with oil refinery waste gas? What are the waste gas treatment methods used for these odorous waste gases in oil refineries? The following with the Everest blue editor to understand.

The principles of refinery exhaust treatment include the safety and reliability of the purification equipment itself and the soundness and fairness of the equipment design. If one of the two has problems, there must be a safety hazard. Refinery waste gas treatment common methods are biological decomposition method, activated carbon adsorption method, plasma method, plant spray liquid deodorisation method and UV photolysis purification method, etc.

Refinery activated carbon adsorption process: activated carbon adsorption method is the use of activated carbon internal open space idle structure is developed, there is a huge surface area principle to adsorb through the activated carbon pool of malodorous gas molecules, the initial processing efficiency of up to 65%, but is very easy to saturate, usually a few days that is, the failure of the need for frequent replacement.

Refinery plasma deodorisation process: plasma method is the use of high-pressure electrodes emitting ions and electrons, the principle of destroying the structure of malodorous molecules, bombardment of the malodorous molecules in the exhaust gas, thereby cracking the malodorous molecules, the low concentration of malodorous gases purification effect can be significant, in normal operation can be reached more than 80%, can handle a variety of malodorous gas fully composed of a mixture of gases, not subject to the effects of humidity, and no secondary pollution!

Refinery UV photolysis process: in TiO2 photolysis catalytic oxidation equipment, high-energy ultraviolet beams and air, TiO2 reaction generated by ozone, -OH (hydroxyl radicals) on the malodorous gases to carry out synergistic decomposition and oxidation reaction, while large molecules of malodorous gases in the ultraviolet light to make the chain structure break, so that the malodorous gas substances into small molecular compounds without odour or complete mineralisation, born water and CO2, after reaching the standard, it is discharged into the atmosphere through the exhaust pipe, and the whole decomposition and oxidation process is completed in 1 second.

The above is how to deal with oil refinery waste gas is introduced, the specific use of which method is required for comprehensive consideration, if the air volume is relatively large, or the concentration is relatively high, you may need to use catalytic combustion or rto incineration process, the specific programmes and quotations can be your needs to tell our engineers, to develop a detailed programme for you Oh.
