Description
Technical field
The present invention relates to the Processes and apparatus that a kind of low grade heat energy utilizes, particularly to a kind of deep-etching direct-fired heat pump technology of high salinity oil field extracted water and equipment.
Background technology
China's energy-consuming becomes increasingly conspicuous based on coal and oil, environmental problem, is second-biggest-in-the-world energy-consuming state.The flue dust caused and SO2 emissions, account for the 70% and 90% of whole nation total release respectively, and the acid rain area that sulfur dioxide (SO2) emissions are formed has accounted for 1/3rd of area.
The Committee of Development and Reform require to strengthen by land gas industry exploring, develop, produce, build in energy-conservation science and technology and Energy saving theory, the research of method.Reduce the energy consumption during oil vapor treatment, simplify the technological process of oil vapor treatment, use the energy-efficient processing equipment of multi-functional unification as far as possible, build Combined Treatment station, oil field.Research uses high-efficiency sewage processing method, reclaims the wet crude in sewage, the purification water that re-injection is qualified；Promote heat pump techniques and reclaim the low-temperature heat quantity of oil field extracted water.
There is the produced-water reinjection after substantial amounts of separation wet crude in China, and before departures, temperature is 40 ~ 60 DEG C, and only Shengli Oil Field is with regard to 300,000,000 tons/year；As can be seen here, the low level recuperation of heat of China's oil field extracted water has a high potential.People are paying close attention to always and how to recycle this partial heat energy and come the production for oil field and service for life, solve the pollution problem (simultaneously as former oil and gas belongs to scarce resource for China, it is therefore necessary to save and use) because burn crude or natural gas cause simultaneously.The feature of this partial heat energy is that grade ratio is relatively low, utilizes heat pump to improve its temperature, can save substantial amounts of natural gas and crude oil.The waste heat of considerable recovered water is discharged in air, i.e. causes thermal pollution to waste again resource.On the one hand, along with the exploitation in oil field enters the middle and later periods, the oil-polluted water water yield of oil well is increasing；On the other hand, petroleum pipeline heat tracing, wet crude dewatering process, the outer defeated heating of wet crude, multi-purpose station in winter, the substantial amounts of building of production crew need heating.Current above-mentioned heat supply principal mode is to use gas fuel boiler, using coal-burning boiler on a small quantity, the energy utilization mode of this form really uses burning high-grade fuel energy to obtain low grade heat energy, and energy efficiency is relatively low, the using energy source thermal efficiency of this heating furnace is about 80%Fire is usedEfficiency is only about 30%.Based on above-mentioned consideration, using compression heat pump or absorption heat pump is a problem that must solve for oil transportation heat tracing, crude oil dehydration, heating crude oil and life heating.Oil field extracted water compression heat pump has produced in oil field and has successfully been applied in life, achieve the most energy-conservation and environment protecting, but compression heat pump uses electric drive, electricity price is higher, and relatively low equipment payoff period longer (2 3 years) that makes of natural gas inside price, constrain the enthusiasm that production unit is promoted, and direct fired absorption heat pump can realize fuel combustion and directly drive, need not with motor driven compressor, comprehensive heating efficiency 1.6 2 can be realized, be enhanced about more than once than the efficiency of current stove about 80%.
In the past few years it was verified that use direct fired absorption heat pump, heated wet crude or coolant-temperature gage can reach more than 80 DEG C, the most also have the high Energy Efficiency Ratio of comparison (about 1.8).
Several years ago, the oil fields such as triumph, Central Plains have all carried out the direct-fired heat pump heating of oil field extracted water or wet crude dehydration and the test of outer defeated heating and application, although achieving higher Energy Efficiency Ratio, but owing to most of oil field extracted waters are strong to metal protection, fouling is serious, the most in the application for the safety of equipment, before low pressure evaporator, add clear water circulating heat exchange system, thus also make to add the one-level temperature difference and circulating pump merit；For the dehydrothermal of wet crude, also use first with direct-fired heat pump clear water, then the technique with clear water heating aqueous crude oil, therefore there is problems in that 1, recovered water heat exchanger seriously corroded, perforation, rear employing degree titanium heat exchanger tube, but cost is the highest；2, recovered water fouling of heat exchangers is serious, and after 1 to two year, blocking cannot use；3, recovered water clear water heat exchanger makes the temperature entering direct-fired heat pump oil field extracted water low pressure heat exchanging evaporator only have 35 40 DEG C, reduces 8 10 DEG C than recovered water temperature；4, recovered water clear water heat exchange process needs water pump longtime running；5, in the temperature heat pump more direct-fired than recovered water that wet crude high temperature clear water heat exchanger makes wet crude be finally reached, high temperature clear water output reduces 20 80 DEG C, and entropy increases relatively big, reduces heating efficiency；6, wet crude high temperature clear water heat exchanger requirements of process water pump longtime running；7, in low-pressure absorber, atmospheric condenser, the temperature difference does not has echelon to utilize, and the entropy adding system increases.
