Description
Technical field: the invention belongs to oil and gas purification techniques field, be specifically related to a kind of from peracidity oil and gas, especially from containing high concentration CO S, H
2in the acid oil and gas of S and mercaptan sulfides, efficiently remove the sweetening agent of acidic components.
Background technology: conventionally contain various acidic components from the Sweet natural gas of gas field extraction, these acidic components mainly comprise H
2s, COS and RSH sulfides and CO
2.Acidic components type and content in each gas field Sweet natural gas differ greatly, same gas field acidic components content in its Sweet natural gas of different steps of exploitation is also different, and in Sweet natural gas, organic sulfur content can have with the prolongation of gas-field exploitation time increase in various degree conventionally.
The CO of high density
2can reduce the calorific value of Sweet natural gas; H
2the existence of S not only can produce to transport pipe corrosion but also serious harm user's health; And COS is as the main component of contained organosulfur in Sweet natural gas, if it is not removed, can make on the one hand to take the downstream chemical process poisoning of catalyst that Sweet natural gas is raw material, on the other hand, COS unprocessed and that be discharged in atmosphere can form SO
2, promote photochemical reaction, bring serious environmental problem.Meanwhile, even if these sulfide also have insufferable smell under extremely low concentration level.Therefore Sweet natural gas manage defeated before, contained acidic components especially sulfide must be removed to particular value.For example GB17820-1999 stipulates H in the civilian secondary Sweet natural gas of China
2s≤20mg/Nm
3, total sulfur≤200mg/Nm
3, CO
2≤ 3% (mol).
Alkanolamine method is the common method that removes these acidic components, and conventional hydramine has monoethanolamine (MEA), diethanolamine (DEA), methyl monoethanolamine (MMEA), diethylethanolamine (DEEA), trolamine (TEA), diisopropanolamine (DIPA) (DIPA), diglycolamine (DGA) and N methyldiethanol amine (MDEA).Conventionally these hydramine can remove most H in Sweet natural gas
2s and CO
2, but use merely hydramine to be conventionally difficult to effective elimination organosulfur.As MEA and DEA are about respectively 45%-50%, 20-25% and 0-10% to the decreasing ratio of thiomethyl alcohol, sulfur alcohol and propylmercaptan.For the COS of effective elimination Sweet natural gas middle and high concentration, known technique often adopts syllogic flow process, and two absorption towers add a COS hydrolysis reactor, and first sour natural gas removes most H in the first absorption tower
2s and CO
2, after intensification, enter hydrolysis reactor and make COS hydrolysis, then lower the temperature and further remove CO remaining and that hydrolysis reaction generates by second absorption tower
2and H

3unstripped gas.
In the patent US4336233 of BASF AG, described and take MDEA as main solvent, and the piperazine that adds 0.05～0.8mol/L is that activator removes the H in gas mixture
2s, CO
2and COS.
US6740230B1 and 6337059B1 be take equally the MDEA of piperazine activation and are removed the H in sour gas as solvent

It is main solvent that CN1421264A and 1887406A all be take MDEA and bulky amine, and adds appropriate solubility promoter and catalyzer to remove the H in gaseous mixture
2s and most of organosulfur.
Aforesaid method does not all relate to high simultaneously high containing H containing organosulfur
2the decontamination effect improving of the oil and gas of S.H in oil and gas
2the content of S is up to 15% (mol) left and right, and organic sulfur content surpasses 600mg/Nm simultaneously
3, even reach 2000mg/Nm
3time, adopt above-mentioned solvent be all difficult to make to purify in oil and gas acidic components content especially total sulfur content reach standard-required.
Summary of the invention: the object of the invention is to, for high simultaneously high containing H containing organosulfur in oil and gas
2the situation of S, proposes a kind of high-efficient purification sweetening agent (Unitedly developed desulfur solvent is called for short UDS), is removing high density H
2s and CO
2time, efficiently removing the organic sulfides such as high concentration CO S and mercaptan, single stage method is removed to each acidic components the desired value of requirement.
