There is a large amount of low temperature waste heat of 40~60 ℃ in oil field site stations. In response to the country wide call for “Energy Conservation and Emission Reduction” initiative, it is considered to recycle the waste heat recovered from oil field produced water. However, the waste heat from oil field produced water cannot heat the crude oil to above 65 ℃ via direct heat transfer. Therefore, heat pumps are needed to raise the temperature. Taking into consideration the site specific conditions and engineering technology of the station, the research conclusions of compression heat pump and absorption heat pump option selection in terms of technical and economic aspects can be drawn through the technical and economic analysis of these two types heat pumps. To conclude, it is feasible to replace the heat furnace in oil field site station with heat pump. This paper could be used as a reference for the engineering design of heat pumps.
