Let's talk about tail gas and waste gas first. There is no difference between tail gas and waste gas. They all contain a lot of carbon monoxide, nitrogen oxides, hydrocarbons, soot particles and so on, but each manufacturer of purification equipment has a different name. There is a well-known domestic company, Shijiazhuang Lanyu Purification Machinery and Equipment Co., Ltd., which mainly produces tail gas purification devices. If necessary, you can contact us.
