Description
Technical field
The utility model relates to a kind of desulfurizer for high sulfur-containing natural gas, particularly the organic permeable membrane permeation sepn of high sulfur-containing natural gas desulfurizer.
Background technology
The Sweet natural gas of some oilfield exploitation of China, as in the tower of Tarim Oilfield, in Harrar Ha Tang, Lungu area individual well pilot production process, most well surveyings obtain H in Sweet natural gas
2s content is very high, its concentration from 3000ppm to 32000ppm not etc.In pilot production process, the natural gas, because sulphur content of extraction is high, can only will after condensate oil Separation and Recovery wherein, be generally that emptying is burned.Not only cause the waste of a large amount of natural gas energy resources, a large amount of greenhouse gases of output, pollute physical environment simultaneously.And there is following problem in conventional dry desulfurization and chemical absorption method sulfur method:
Dry desulfurization adopts solid desulfurating agent, by Sweet natural gas H
2s content 30000ppm calculates, and need process H every day
2approximately 4.5 tons of S, by 10% sulphur content, need 45 tons/day of sweetening agents, and doctor solution consumption is huge, and expense is very high; Every processing 1 side's associated gas only sweetening agent expense just up to 4 yuan, high cost, and because digester capacity is huge, cannot be used for skid, field application resettlement difficulty.
Chemical absorption method is the most frequently used method in current selexol process technique, utilizes alkaline alcohol amine aqueous solution to absorb the H in gas
2s and CO
2deng, gained absorbs rich solution and discharges H by intensification, step-down etc. again
2s and CO
2thereby, realize recycling of absorption agent.But absorbed these sour gas H in the time of desulfurizer regeneration
2s and CO
2also can parse, there is no real conversion H
2s, also must arrange sulfur recovery facility, by H
2s is converted into simple substance sulphur, can really realize scavenging process.This appliance arrangement volume is larger, reach whole sledge dressizationes very difficult.
Therefore find a kind of new new technology that is suitable for individual well desulfurization extremely urgent, this new processing requirement sulfur removal technology is simple, and integral device can all become sledge, is convenient to transport and dismounting.
Summary of the invention
The purpose of this utility model is to provide that a kind of flow process is simple, compact construction, be suitable for organic permeable membrane permeation sepn desulfurizer that individual well high sulfur-containing natural gas uses.
The utility model desulfurizer is formed and is connected into system by pipeline by coalescer, well heater, membrane separation apparatus and digester, described coalescer is connected with sulfur-containing gas raw material input tube, the outlet of coalescer is connected with well heater, membrane separation apparatus successively, the side that sees through of described membrane separation apparatus is connected with high-concentration hydrogen sulfide waste pipe, the side that do not see through of described membrane separation apparatus is connected with the entrance end of digester, and digester outlet connects desulphurised natural gas delivery conduit.
Described well heater is connected with hot water inlet pipe and hot water outlet pipe.
Described digester is connected with safety relief outlet pipe, and this safety relief outlet pipe imports high-concentration hydrogen sulfide waste pipe.
Two tanks in parallel that described digester comprises changeable use.
Described coalescer, well heater, membrane separation apparatus and digester integrated installation form a sledge block assembly (getting final product the integrating device of integral shift) on same base.
The core component of this high sulfur-containing natural gas desulfurizer is film desulfurization separator, by organic permeable membrane to H in unstripped gas
2s carries out roughing out, more than 90% H
2s is penetrated in high gassiness, can emptying burn or focus on.H
2s content be reduced to 100-1000ppm Sweet natural gas enter digester, by the sweetening agent a small amount of H in adsorbed gas again
2s, H in the Sweet natural gas that ensures to export
2s content is less than 20ppm, can enter gas distributing system, makes this part Sweet natural gas be purified and recycle.This apparatus structure compactness, cost are low, easy to operate, work simplification, and all devices in device can be arranged on same base plate compactly, is integrated into sledge block assembly.In oilfield exploitation, this device is integral shift easily, for the desulfurization of the each well head association in oil field Sweet natural gas.
Brief description of the drawings
Fig. 1 is the organic permeable membrane permeation sepn of this high sulfur-containing natural gas desulfurizer structural representation.
In figure: 1-raw material gas inlet, 2-hot water outlet, 3-hot water inlet, 4-coalescer, 5-well heater, 6-membrane separation apparatus, 8,7-digester, 9-waste gas outlet, 9 '-high-concentration hydrogen sulfide waste pipe, the outlet of 10-desulphurised natural gas, 11-sledge piece base, 12-safety relief outlet pipe, F1, F2, F3, F4, F5, F6, F7, F8, F9-valve.
Embodiment
Below in conjunction with brief description of the drawings to structure of the present utility model and working process.
As Fig. 1, coalescer 4, well heater 5, membrane separation apparatus 6, digester 7 and digester 8 connect into system by pipeline and are integrated in base 11 and form sledge piece.
