Description
Technical field
The present invention relates to the oil field oil production technology, particularly a kind of oil shale retort oil extraction process.
Technical background
The oil production technology that domestic existing carbonization furnace matches all adopts direct process for cooling.Its technical process is: the destructive distillation gas in the stove is exported in the collecting tubule via upcast, bridge tube by the negative pressure that produces from the dispatch machine.Be recycled water washing when flowing through bridge tube after the washing tower washing.Destructive distillation gas after the washing is divided into two portions after the pressurization of dispatch machine: a part enters process furnace as circulation destructive distillation gas, and another part cools off through cooling tower, and steam and the most of condensation of oily vapour in the destructive distillation gas are got off.Be cooled to 55～65 ℃ destructive distillation gas, a part is as the accumulation of heat of process furnace burning destructive distillation gas firing, and remainder is as boiler oil with for the generating of destructive distillation pneumoelectric station.Circulation destructive distillation gas is heated to 700～750 ℃ through process furnace, send in the gas retort to replenish the required heat of destructive distillation.
The required main air of gas retort be the air sent here by the main air blower fan through saturator, the water that gets off by the washing tower humidification of heating, the main air saturation ratio (75～85 ℃) that reaches regulation is delivered to single stove by the main air house steward, is fed in the gas retort by furnace bottom public attention again.
The oil that destructive distillation gas is washed, cools down through collecting tubule, washing tower, cooling tower etc. flows into basin, sends into test tank by oil pump, after the sedimentation of heating, the metering of dehydration dipping, is fed through the finished product jar through oil pump.In order to strengthen the cooling performance of destructive distillation gas, establish water cooling tower.By the cold water pump ammoniacal liquor in the cooling pool is extracted out, send water cooling tower by the forced-air blast cooling after, by cooling pump with ammoniacal liquor deliver to destructive distillation air cooling but cat head spray cooling and purifying destructive distillation gas.
The problem that this technology exists is:
1) technology is comparatively simple, and the cooling and purifying of destructive distillation gas and the humidification of air, heating is integrated;
2) this technology cooling water amount is big;
3) oily water separation is pond formula structure, and separating effect is relatively poor;
4) establish the ammoniacal liquor cooling and use water cooling tower, environmental pollution is more serious.
Summary of the invention
The purpose of this invention is to provide a kind of good separating effect, can alleviate environment, water-saving effective oil shale retort oil extraction process.
The object of the present invention is achieved like this, oil shale retort oil extraction process, and its technical process is:
Under the suction that gas blower produces,, import effuser from the carbonizing gas of gas retort furnace roof through upcast, bridge tube; Be recycled ammoniacal liquor when flowing through bridge tube and spray cooling; Phlegma and first cooled thick carbonizing gas enter gas-liquid separator along air suction pipe and carry out gas-liquid separation;
The thick destructive distillation gas that gas-liquid separator separates goes out enters the transverse tube type inter cooler along pipeline; In transverse tube type inter cooler device, after circulating hot water and the cooling of circulation moisture indirect two-stage, enter spray catcher, catch except that entering oil-absorption tower by the bottom behind the shale mist of oil of carrying under one's arms in the destructive distillation gas;
In oil-absorption tower, fully contact, come out from the oil-absorption tower cat head after removing the shale mist of oil of carrying under one's arms in the destructive distillation gas, enter electrical tar precipitator with the heavy shale oil countercurrent flow of spraying from cat head;
Under the high voltage direct current field action, shale mist of oil residual in the destructive distillation gas is removed; Destructive distillation gas after the purification is through the pressurization of destructive distillation tympanites blower fan, and a part send process furnace as the circulation carbonizing gas; A part is delivered to desulfurization unit; Clean carbonizing gas after the desulfurization, except that sending the process furnace as the burning carbonizing gas, remainder dispensing generating is used;
The ammoniacal liquor shale oil mixed solution that gas-liquid separator separates goes out is from flowing in the mechanize profit clarifying tank; The upper and lower two sections phlegma of transverse tube type inter cooler water sealed tank flows into heavy shale oil groove certainly through water seal, and the heavy shale oil is pumped to oil-absorption tower cat head circulation sprinkling washing, purifying destructive distillation gas through submerged pump; Oil-absorption tower, electrical tar precipitator and destructive distillation tympanites blower fan phlegma everywhere through flowing into the lightening shale oil groove certainly after the water seal separately, are pumped to mechanize profit clarifying tank through submerged pump; After each groove emptying liquid imports underground emptying groove, pump to mechanize profit clarifying tank by submerged pump;
Shale oil is come out after flow into the shale oil storage tank, further leaving standstill dehydration by mechanize profit clarifying tank after mechanize profit clarifying tank standing separation, extracts outer selling out by finished product shale oil pump; Ammoniacal liquor flows into the cyclic ammonia water groove certainly behind the regulator of level of mechanize profit clarifying tank, the thick carbonizing gas of cooling is sprayed at most of gas retort bridge tube place that send after the pressurization of cyclic ammonia water pump; Small part, is handled through the remained ammonia pumps water after the remained ammonia storage tank is stored as remained ammonia; Be deposited on the shale dregs of fat of mechanize profit clarifying tank bottom, mix bunker coal after scraping continuously, collect by the scraper plate machine.
The required main air of described gas retort is 75～78 ℃ by the air after the air blower pressurization with one section hot water temperature who comes out of transverse tube, and is saturated in saturator, augments part steam and reaches after 75～78 ℃ of the main air temperature of saturation by the main air house steward and give bottom each gas retort.
Advantage of the present invention is: utilize sophisticated equipments such as the cooling indirectly of transverse tube type interchanger, cyclone dust removal, material filling type oil-absorption tower, static trap for oil, elevated temperature heat air-valve to reclaim shale oil; Can improve 10～15% than the traditional technology oil recovery rate, oil-contg can be reduced to 1g/Nm in the destructive distillation gas after the purification
3Below; The shale oil light ends that produces increases, and well cuts content reduces; Water in system with the indirect contact of destructive distillation gas, recycle, do not have new sewage and produce; Static was caught oily device and is cut off the power supply total system DCS operation, level of automation height automatically when the flow interlocked control of the water yield and destructive distillation gas, the oxygen level in the destructive distillation gas surpassed capping; Environmental protection, energy-conservation and net effect is obvious.
