How to handle exhaust gases from tar loading
Thread Content
At present, exhaust gas leakage occurs quite severely during the loading of tar and crude benzene; especially when loading tar, the odor is very strong. Environmental protection requirements are becoming increasingly strict. I would like to ask my colleagues: how do you handle the exhaust gas generated during loading? What process to use? Are there any companies you can recommend? :handshake
It can be integrated with the flue gas collection and treatment system of the storage tank for joint treatment
Our storage tank is part of a negative-pressure gas system; such systems that discharge directly into the air cannot be used, as it’s difficult to control the oxygen content
I think it would be possible to use systems similar to those used for LNG and synthetic ammonia, where the exhaust gases generated during loading are sent into a boiler, where they can be decomposed through combustion. However, the problem is that this might require an upgrade in the explosion-proof rating of the boiler. Alternatively, a VOC treatment device can also be used for treatment, but the cost is high.
By the way, how does your company handle dust-containing tar?
By carrying out technical upgrades or installing oil and gas recovery devices in the tank area, the treated emissions can be released into the atmosphere in compliance with standards. The condensation + adsorption recovery system can achieve a 97.5% recovery efficiency, including the condensation and adsorption processes. If there is an odor, appropriate deodorization facilities can be installed.
We have never sold tar containing dust; we clean the residue in our storage tanks every 5-6 years.
A venturi injector absorption method or a spray tower absorption method can be used; the structure is relatively simple, and the cost is around 100,000 yuan!
