Application of waste heat recovery technology in union station and analysis of energy efficiency

Abstract

The oily wastewater through union station was between 40-70 °C. The sewage was injected to the ground or direct discharge after treatment and it resulted in heat waste in union station. In the meaning time, there were many energy demands in union station, such as building heating, the crude oil heating, the liquid heating and so on. Paper summarized the current status of heat waste in oilfield and absorption heat pump technology. The paper took the absorption heat pump heating project in Kenxi Oilfield Station as an example. The paper introduced the program design. And the energy consumption was compared before and after the transformation. The energy-saving efficiency (ζ) is up to 63% and the COP of lithium bromide unit was 1.54. It proved the absorption heat pump technology had distinct advantages of energy-saving in the union station.
