Abstract

The invention relates to a high-effective remover of hydrogen sulfide at normal temperature and a preparation method thereof, in particular to a compound high-effective sulfur remover and the preparation method thereof. The sulfur remover contains N-methyl diethanol amine with the content of 93.5 weight percent to 96 weight percent, and the other components are an anti-foaming agent, a corrosion inhibitor, an antioxidant and an intensifier. The preparation method of the sulfur remover is that 93.5 portions to 96 portions (all portions are weight portions) of N-methyl diethanol amine, 0.05 portion to 0.2 portion of anti-foaming agent, 0.02 portion to 0.05 portion of corrosion inhibitor, 0.05 portion to 0.2 portion of antioxidant and 3 portions to 6 portions of intensifier are stirred in a stirring kettle into uniform solution, that is, the compound sulfur remover. The compound sulfur remover of the invention solves the problem that the present MDEA compound sulfur remover can affect the sulfur removing effect by reacting with CO2.

Description

technical field [0001] The invention relates to a normal-temperature high-efficiency hydrogen sulfide removal agent and a preparation method thereof, in particular to a compound type high-efficiency desulfurization agent and a preparation method thereof. Background technique [0002] At home and abroad, more and more attention has been paid to the research on the treatment of hydrogen sulfide waste gas. The desulfurization methods can be divided into dry method and wet method according to its weak acidity and strong reducing property. The dry method is to use the reducibility and flammability of hydrogen sulfide to desulfurize or directly burn with solid oxidant or adsorbent, including the Claus method, iron oxide method, activated carbon method and Carter Sulph method. The wet method is divided into liquid absorption method and absorption oxidation method according to the different compound desulfurizers used. The liquid absorption method includes a chemical absorption met...
