Treatment of highly toxic exhaust gases
Thread Content
Should highly toxic Class A exhaust gases and other non-highly toxic Class A exhaust gases in the same workshop be treated separately or together? Is there a **source for the stripes?**
There are no regulations; approval for environmental impact assessment and safety assessment is sufficient
In principle, they should be treated separately to reduce the risk of gases mixing together; once mixed, all gases become highly toxic, which leads to increased investment and costs
Why do investments and costs rise after mixing? Are there any provisions governing this separate handling?
It depends on the volume; if ordinary exhaust gas at several ten thousand cubic meters per hour is treated as highly toxic gas, it would require significant costs. If the flow rate of each gas is very low, using one tower is the way to save costs
