Description

Environment-friendly type H2S scavenger and preparation method thereof
Technical field
The invention belongs to chemical field, and in particular to environment-friendly type H2S scavenger and preparation method thereof.
Background technology
As processing crude oil becomes weight, the quantitative change of crude oil sulfur-bearing is big, and the liquefied gas sulfide hydrogen of generation and sulfur-containing oxide etc. contain Sulphur gas percentage is constantly raised.So liquefied gas is all very important to the injury of human body to the pollution caused by environment, country Also regulation dispatches from the factory liquefied gas sulfur-bearing standard less than 5ppm, moreover element sulphur is a kind of important mineral resources, it is impossible to waste, Need to must reclaim as far as possible.
Content of the invention
Goal of the invention：Present invention aims to the deficiencies in the prior art, provide a kind of environment-friendly type H2S scavenger.
Another object of the present invention is to providing above-mentioned environment-friendly type H2The preparation method of S scavenger.
Technical scheme：In order to reach foregoing invention purpose, the present invention is specifically performed by：Environment-friendly type H2S is removed Agent, it is characterised in that including the component of following parts by weight：60 ~ 100 parts of diethanol amine, 5 ~ 10 parts of dimethicones, 2 ~ 6 Part ethanol, 1 ~ 5 part of magnesium stearate, the water of 1 ~ 5 part of NaOH and 5 ~ 8 parts.
A kind of preferred version, is grouped into by the group of following parts by weight：80 parts of diethanol amine, 5 parts of dimethicones, 2 Part ethanol, 1 part of magnesium stearate, the water of 1 part of NaOH and 5 ~ 8 parts.
Prepare environment-friendly type H2The method of S scavenger, measures each raw material by formula, pours reactor into, by reactor water-bath Pot be heated to 50 ~ 60 DEG C, be down to room temperature after continuously stirred 2 ~ 6 hours, after reactor is heated with the method for heating water bath again To 60 DEG C, and insulated and stirred 12 ~ 24 hours.
The method heated using Secondary water-bath, prevents the miscible phenomenon of vacation during first time heating water bath, improves further each Plant the mixed effect of Materials Solvents.
Beneficial effect：The present invention compared with conventional art, with advantages below：
（1）Selective high, sulfurous gas absorptivity is more than 95%；
（2）Sulfur recovery rate is high, and scavenger usage amount is few, low cost；
（3）To environment non-secondary pollution.
