PRODUCT DESCRIPTION

Composite desulfurizing agent can selectively take out H2S、CO2 from refinery gas and natural gas.

FEATURES

The product is composed by multi-component. Its main component is MDEA and some kinds of high-effective additives. It has higher activity and desulfurizing effect than N-methyldiethanolamine. Its desulfurizing selectivity, capacity for absorbing acid gas, stability, antifoaming ability and regeneration ratio are fairly better than N-methyldiethanolamine. It has good chemical stability, better resistance to oxidation, lower corrosion and lower freezing point. It can be used very conveniently.
