Energy system studies according to the Pinch Technology have shown that one way to reduce the energy consumption at the BP Refinery would be the use of a heat pump for low-pressure (4.5 bar) steam production. As heat source heat from hot products or from a special water system, providing the Volvo factory close to BP with heat, could be used. The technical and economical calculations have shown, that for raising 7 tons/h steam with an evaporating temperature of 60-70°C, a two-stage heat pump (Rl14jH 0) is needed. The total investment cost w~en hot products are used as heat source is 70% higher than the cost of the heat pump itself and the pay-back period is about 3.5 years. With the Volvo water as heat source the pay-back period ranges between 2.0-2.6 years (for direct steam compression) with small annual energy recovery and nearly 3 years (two-stage heat pump) with high annual energy recovery.
