How is the exhaust gas from atmospheric pressure storage tanks treated?
Thread Content
Atmospheric pressure storage tanks should also generate exhaust gases; can these exhaust gases be released directly? How is it usually handled?
For VOC treatment, we use RTOs
For VOC treatment, we use RTOs
According to the regulatory requirements, if there are no emission limits specified and the substance is non-toxic, harmless, and not explosive, it can be released directly into the atmosphere； The main three treatment methods that do not discharge substances directly into the atmosphere are incineration, washing, and flaring.
Looking at the storage media, those containing VOCs generally use absorption methods for handling heat and cold; this is handled by the manufacturers of the complete systems, who are responsible for ensuring compliance with emission standards
Simple and cost-effective method: send it to the tank farm flare.
To determine whether the breathing exhaust gas from atmospheric pressure storage tanks can be discharged directly, one can refer to the \"5.2 Requirements for Pollution Control of Volatile Organic Liquid Storage Tanks\" in the \"Emission Standards for Pollutants in the Petrochemical Industry\" (GB 31571-2015) and the \"Emission Standards for Pollutants in the Petroleum Refining Industry\" (GB 31570-2015), in order to decide whether an oil and vapor recovery system is necessary. If an oil and gas recovery unit is not required after comparison, the breathing exhaust gas from the storage tank can be discharged directly.
According to environmental regulations, this is based on the opinions from the 9th floor; others have suggested using a flare stack, as pressure vessels cannot be directly connected to the flare system.
