The main reason of amine solution bubbling is the high content of mechanical impurity in amine solution. The filtering method is the effective one to eliminate the mechanical impurity in amine solution. The operation of desulfurization system in Dalian West Pacific Petrol-Chemical Co. , Ltd.shows that it is necessary to make amine solution in clean production. It will reduce the amine solution bubbling and decrease the cost of high efficient desulfurizer. Obvious economic benefit will be shown.
