Is it required by regulations for the gases discharged from the safety valves of nitric acid storage tanks and glacial acetic acid storage tanks to be sent to an absorption tower? Is it standard to empty it directly?

The exhaust gases emitted during normal operation from the nitric acid storage tanks and glacial acetic acid storage tanks are sent to the tail gas absorption tower. Is it required by regulations that the gases emitted by the safety valves also be sent to this tower? How is it usually done?
Is the gas from the storage tank sent to the absorption tower via an induced draft fan?
Air cannot be released directly; it must be treated first
It is unclear whether the liquid or gas is discharged from the safety valve; it is not reasonable to send it directly to the adsorption tower. The discharge from a safety valve is characterized by uncertainty and instantaneous release, and sending it directly to the adsorption tower can affect the treatment efficiency. It is recommended to send it to a buffer tank first before proceeding to the adsorption tower
It cannot be discharged directly; it should be absorbed in an absorption tower. According to the regulatory requirements, there are now not only requirements regarding emission concentrations but also requirements regarding the total amount of emissions.
Could you please send me which standard it is? Are there any requirements as well for abnormal and accident emissions?
The exhaust gas from the nitrogen-sealed tank is under slight pressure
