Industry summary

Petroleum refining and petrochemical industry, coal chemical industry, chemical storage and transportation are the key industries of VOCs emission. The waste gas emission mainly comes from the production process, and the other emission sources come from 12 sources: leakage of dynamic and static sealing points of equipment; volatile loss of organic liquid storage and reconciliation; volatile loss of organic liquid loading and unloading; waste water collection and transportation, storage, treatment and disposal process escape; combustion flue gas emission; organized emission of technology; unorganized emission of process; emission during sampling process; flare emission; waste gas emission; Abnormal conditions include start-up, shutdown and maintenance discharge; cooling tower and circulating water cooling system release; accident discharge.

Industry solutions

Common components:product oil, benzene, toluene, ethylbenzene, polyethylbenzene, cumene, styrene, raffinate, naphtha, ethylene glycol, acetone, vinyl acetate, waste alkali, residual oil, aromatics, sulfide, etc

The production process is complex, the emission sources are multiple, and the concentration of waste gas fluctuates greatly. Combined with the production process of customers, Huashijie develops a targeted "one plant, one policy" VOCs comprehensive control scheme, and provides a comprehensive HAZOP analysis. Oil recovery should be adopted for all kinds of storage tank breathing and oil loading and unloading, and high concentration VOCs emission such as wastewater treatment system should be treated by closed collection to achieve standard discharge. In view of the priority adsorption / condensation recycling of process waste gas such as process pool vent gas, acid water tank process tail gas, oxidation tail gas and reforming catalyst regeneration tail gas, those with complex components and difficult to use should be sent to the flare system for treatment or destruction measures such as catalytic oxidation and regenerative oxidation, so as to achieve the standard emission.
