We have a project in a petrochemical plant to treat the VOCs from the sewage tank. There are hydrocarbons, including benzene，toluene, and xylene, and H2S in the stream. The inlet concentration of non-methane hydrocarbon is about 6,000 mg/m3, and the air flow rate is 1,700 m3/h. The current technological process is wet scrubber & plasma & activated carbon. However, the effect is not good, and we can't meet the emission standard of VOCs or non-methane hydrocarbon. And it's very strange that sometimes the outlet concentration of non-methane hydrocarbon is even higher than its inlet concentration.
Do anyone of you have experience in similar cases? Could you give me some advice?
