Description
Technical field
The present invention relates to the Processes and apparatus that a kind of low grade heat energy utilizes, particularly the direct-fired heat pump technology of a kind of deep-etching high salinity oil field extracted water and equipment.
Background technology
China's energy-consuming be take coal and oil as main, and environmental problem becomes increasingly conspicuous, and is second-biggest-in-the-world energy-consuming state.The flue dust causing and SO2 emissions, account for respectively 70% and 90% of national total release, and the acid rain area that sulfur dioxide (SO2) emissions form has accounted for 1/3rd of area.
The Committee of Development and Reform require to strengthen the research of energy-conservation science and technology in exploration, exploitation, in producing, building of gas industry by land and Energy saving theory, method.Reduce the energy consumption in oil gas processing procedure, simplify the technological process that oil gas is processed, adopt the energy-efficient treatment facility of multi-functional unification as far as possible, build Combined Treatment station, oil field.Research adopts high-efficiency sewage processing method, reclaims the wet crude in sewage, and what re-injection was qualified purifies waste water; Promote the low-temperature heat quantity that heat pump techniques reclaims oil field extracted water.
There is the produced-water reinjection after a large amount of separated wet crudes in China, and before departures, temperature is 40 ~ 60 ℃, 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 part heat energy and carry out production and the service for life for oil field, solve the pollution problem (simultaneously because former oil and gas belongs to scarce resource concerning China, being therefore necessary to save to use) because burn crude or natural gas cause simultaneously.The feature of this part heat energy is that product bit comparison is low, utilizes heat pump to improve its temperature, can save a large amount of natural gases and crude oil.The waste heat of considerable recovered water is discharged in atmosphere, 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 companion heat, wet crude dewatering process, the outer defeated heating of wet crude, winter, multi-purpose station, a large amount of building of production crew needed to heat.Current above-mentioned heat supply principal mode is to adopt gas fuel boiler, a small amount of coal-burning boiler that adopts, the energy utilization mode of this form is actual is to adopt burning high-grade fuel energy to obtain low grade heat energy, energy efficiency is lower, the using energy source thermal efficiency of this heating furnace is in 80% left and right
fire is usedefficiency is only in 30% left and right.Based on above-mentioned consideration, adopting compression heat pump or absorption heat pump is a problem that must solve for oil transportation companion heat, the dehydration of crude oil, heating crude oil and life heating.Oil field extracted water compression heat pump has successfully obtained application in field produces and life, obtained energy-conservation and environment protecting significantly, but compression heat pump adopts electric drive, electricity price is higher, and the lower equipment that makes of natural gas inside price is grown (2-3 years) payoff period, restricted the enthusiasm that production unit is promoted, and direct fired absorption heat pump can be realized fuel combustion and directly drives, do not need with motor drive compression machine, can realize comprehensive heating efficiency 1.6-2, than the efficiency of current stove 80% left and right, be enhanced about more than once.
Facts have proved in the past few years, adopts direct fired absorption heat pump, is heated wet crude or coolant-temperature gage and can reaches more than 80 ℃, also has higher Energy Efficiency Ratio (1.8 left and right) simultaneously.
Several years ago, test and the application of the direct-fired heat pump heating of oil field extracted water or wet crude dehydration and outer defeated heating all carried out in the oil fields such as triumph, Central Plains, although obtained higher Energy Efficiency Ratio, but because most of oil field extracted waters are strong to metal protection, fouling is serious, therefore in application for the safety of equipment, before low pressure evaporator, added clear water circulating heat exchange system, thereby also made to have increased the one-level temperature difference and circulating pump merit; Dehydrothermal for wet crude, also adopted and first used direct-fired heat pump clear water, then with clear water, heated the technique of wet crude, therefore had following problem: 1, recovered water heat exchanger seriously corroded, perforation, rear employing degree titanium heat exchanger tube, but cost is too high; 2, recovered water fouling of heat exchangers is serious, one to two year afterwards obstruction cannot use; 3, recovered water-clear water heat exchanger makes the temperature that enters direct-fired heat pump oil field extracted water low pressure heat exchanging evaporator only have 35-40 ℃, than recovered water temperature, has reduced by 8-10 ℃; 4, recovered water-clear water heat exchange process needs water pump to move for a long time; 5, wet crude-high temperature clear water heat exchanger makes the temperature that wet crude finally reaches reduce by 20-80 ℃ than high temperature clear water output in the direct-fired heat pump of recovered water, and entropy increases larger, has reduced heating efficiency; 6, wet crude-high temperature clear water heat exchanger requirements of process water pump moves for a long time; 7, in low-pressure absorber, atmospheric condenser, the temperature difference does not have echelon utilization, and the entropy that has increased system increases.
