Description
Technical field: the present invention relates to the selexol process technology, the skid of especially a kind of double tower selexol process is put and application method.
Background technology: along with the continuous progress of the construction of natural gas fields, the block of exploitation, layer position etc. all have in a big way at present, cause impurity component in Sweet natural gas to get more and more, and make natural gas purification processing day by day complicated.In the domestic Sweet natural gas of having exploited, need the impurity of purifying treatment generally to have at present: CO
2, H
2S, N
2, O
2, H
2, He, H
2O etc., the China's natural gas standard mainly contains: " Sweet natural gas " (GB17820-1999), " compressed natural gas used as vehicle fuel " (GB18047-2000); " dry gas " (Q/SH004.1.13.1990) etc.In relevant criterion, mainly foreign matter content and the calorific value of Sweet natural gas are stipulated.According to above products standards, for the H most importantly of impurities in Sweet natural gas
2The requirement of S and total sulfur content, H in defeated Sweet natural gas outside the general requirement gas field
2S content is less than 20 mg/m
3, total sulfur content is less than 200mg/m
3.The production run rule of general sour gas well is: along with the recovery time prolongation of gas well, H
2S content will continue to rise.Therefore should be by the H in Sweet natural gas
2Can be defeated outward after S removes.If do not removed, although temporarily this part Sweet natural gas can be sneaked into to the full dilution H of factory
2S content, but contained H in Sweet natural gas
2S can bring corrosion to equipment, the pipeline of full factory, and along with H
2The continuous rising of S content, may cause outside whole gas gathering station defeated Sweet natural gas all defective.
Summary of the invention: good a kind of double tower selexol process skid is put and application method to the purpose of this invention is to provide sweetening effectiveness, it has solved the problem that exists in present technology, the object of the present invention is achieved like this, it is to be formed by connecting by the first thionizer, the second thionizer, pipeline, tensimeter, ball valve, thermometer, the first thionizer is connected by pipeline with the top of the second thionizer, on the pipeline on the first thionizer and the second thionizer top, be connected two ball valves, and on pipeline, connecting tensimeter; The first thionizer is connected by pipeline with the bottom of the second thionizer, on the pipeline of the first thionizer and the second thionizer bottom, is being connected two ball valves, and on pipeline, is connecting tensimeter; The top of the first thionizer is connected by pipeline with the bottom of the second thionizer, in the middle of pipeline, is connecting ball valve; The top of the second thionizer is connected by pipeline with the bottom of the first thionizer, and in the middle of pipeline, connecting ball valve: the side at the first thionizer one side and the second thionizer is installed with respectively thermometer.
Application method of the present invention is: the first step, unstripped gas (Sweet natural gas) enters the second thionizer again through the first sulphur tower, the H2S of the overwhelming majority is adsorbed at the first thionizer, the second thionizer removes remaining sulphur, when the sulphur content of importing and exporting when the first thionizer was identical, the sweetening agent in the first thionizer was fully saturated, and the sweetening agent in the second thionizer is inhaled sulphur 15% left and right, only need to change the sweetening agent of the first thionizer this moment, the sweetening agent of the second thionizer does not need to change; Second step, after the first thionizer is changed sweetening agent, unstripped gas just advances from the second thionizer, through the first thionizer, goes out, and the H2S of the overwhelming majority is adsorbed at the second thionizer, the first thionizer removes remaining sulphur, when the sulphur content of importing and exporting when the second thionizer was identical, the sweetening agent in the second thionizer was fully saturated, and the sweetening agent in the first thionizer is inhaled sulphur 15% left and right, only need to change the sweetening agent of the second thionizer this moment, the sweetening agent of the first thionizer does not need to change; So recycle, take full advantage of the absorption function of sweetening agent, greatly increase the utilization ratio to sweetening agent, also can effectively reduce working cost; Two thionizers also can be in parallel, uses separately; The 3rd step, when sweetening agent operation one-period, should change sweetening agent, before replacing, should open the fresh water import, with fresh water, sweetening agent is drenched, and blowdown; Then can open the manhole discharging, when discharging, should use upper and lower two thermometers of installing on tower to keep a close eye on temperature variation in tower, prevent sulfide spontaneous combustion in sweetening agent.
Technical parameter of the present invention is: remove the contained free-water of Sweet natural gas; By contained H in Sweet natural gas
