The heat pump is consumed part quality can (mechanical, electrical, etc.) or high potential energy, by a thermodynamic cycle, heat is transferred from the cryogenic object to the objects of high temperature energy utilization system. The high temperature water source heat pump is a class of high-temperature heat pump, which uses waste heat from various industrial wastewater system 70 ℃ ~ 90 ℃ hot water can be used directly for heating and industrial heating.
    In the petrochemical industry, crude oil gathering and transportation system is the basic oil production capacity system, the higher the energy consumption of the system. Typical crude oil systems in the crude oil is removed from the formation to the qualified crude oil processed into the production process, which requires energy consumption, but also power consumption, wherein the energy mainly from oilfield production of natural gas. Reduce heat loss and improve the efficiency of furnace thermal energy consumption savings oilfield waste heat recovery technology application is a weak link.solar power air conditioners
    Lot of oil fields in China belong to the middle and late mining, mining out of the water content of the crude oil giant. 70% water and 30% of the crude oil produced fluid as to be pressurized by the pump from the wellhead to the joint station heating furnace oil-water separator, isolated from sewage temperature between 40 ℃ ~ 60 ℃. Shengli Oil Field, for example, oil extraction wastewater Station 52, the outside sewage water of 720,000 cubic meters / day, sewage water temperature at 50 ° C to 70 ° C. Where the water temperature at the water stations above 60 ℃, 14, outside the displacement of about 260,000 cubic meters / day, a very substantial sum of available energy wealth.
    If the use of high temperature heat pump to extract 5 ° C heat recovery, energy will be recovered to 73,000 kilowatts. Take into account the heat output of the heat pump, up to about 100,000 kilowatts, the equivalent of all combustion heat value of 10t / h crude capacity of 87,600 tons of crude oil per year. If using the heat pump oily wastewater temperature dropped to 20 ℃, 30 ℃ emissions per year can save 350,000 tons of crude oil, crude oil production is equivalent to 1% of Shengli Oilfield. Seen, the application of high-temperature water source heat pump to maximize the use of waste heat resources of oil and petrochemical industry will create billions of dollars or even hundreds of billion of economic value, and create a new energy saving.
