Waste gas treatment is aimed at the treatment of industrial waste gas, such as smoke and dust, peculiar smell gas, toxic and harmful gas, so how to recycle these gases? Let's get to know.

1. Incineration is an effective method for the treatment of organic waste gas with low organic content. After combustion, the organic matter will become harmless water and carbon dioxide, without secondary pollution. The equipment such as flare and heating reaction furnace are used for incineration. Fig. is the process flow chart of combustion process for treating tail gas of long acrylic absorption tower. The waste gas from the top of the absorption tower of the acrylonitrile unit is sent to the dehydration tank for dehydration, and then it is injected into the furnace through the nozzle of the gas burner for incineration.

2. Waste gas recovery and utilization absorption method is to use water or organic solvent as absorbent to absorb harmful substances in organic waste gas and purify the waste gas.

The process is to concentrate the blowdown lines, draw them out by PP fan, enter the absorption tower after pressure lifting, and send the solution absorbed by cold water to acrylonitrile production process. The treatment effect of this method is better.
