The speed has slowed somewhat by the time this century entered, but has progressed at 5%. Asia, and in particular china, rapidly develops at an average annual rate of 20% to 30%. By the end of 2007, global organic amine production capacity has reached 50 million tons. The tail gas generated by the organic amine production line not only pollutes the environment, but also directly affects the physical health of staff. The organic waste gas treatment means that the organic waste gas pollution is eliminated by reducing the use amount of an organic solvent or purifying exhaust gas through different ways by using various technical measures. The organic waste gas pollution source is widely distributed, in order to prevent pollution, besides reducing the use amount of organic solvent to reduce the generation and emission of organic waste gas, exhaust purification is a feasible treatment way at present, and common methods include an adsorption method, an absorption method, a combustion method, a condensation method, a biological method and the like, wherein the adsorption method, the absorption method and the condensation method have the risk of secondary pollution, the biological method has higher cost, although the combustion method has good effect, the content of hydrogen in the waste gas is high (generally 55% -75%), the waste gas is secondarily alkane (methane, ethane, propane and the like) (generally 15% -35%), and the rest is respectively organic amine, ammonia and a small amount of impurities, and because the content of hydrogen in the waste gas is high, the combustion method has the risk of explosion.
