Description
technical field [0001] The invention relates to a production system, in particular to a desulfurizer production system. Background technique [0002] At present, in the desulfurization agent (MDEA) synthesis process, the flow rate of the reactant material is controlled by the stroke of the ethylene oxide feed pump and the monomethylamine feed pump. In the case of fluctuations in the flow of ethylene oxide, the flow of monomethylamine needs to be adjusted artificially, which directly affects the yield and purity of the product. Moreover, the existing desulfurizer production system is not perfect, with low degree of automation and low production efficiency, which does not meet the actual use requirements. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a desulfurizer production system with automatic flow ratio, improved product purity, automatic operation and high producti...
