摘要

The application of post-combustion CO_2 capture represents an alternative strategy to reduce significantly CO_2 emissions from the oil refining industry. Previous studies have shown that the highest costs are related to the provision and use of energy and that these costs could be reduced by utilising excess heat. In the present study, we investigated whether this principle could be applied to the oil refining industry. Four heat supply alternatives were evaluated: Natural Cos Combined Cycle; Natural Gas Boiler; Biomass Boiler; and Excess Heat. These alternatives were evaluated using future energy market scenarios and two levels of heat demand. The Natural Gas Combined Cycle alternative generated high levels of electricity (with CO_2 capture), thereby producing the greatest reduction in global CO_2 emissions. However, the avoided CO_2 emissions from onsite the refinery were highest when excess heat or a biomass boiler was used. In the present study, the capture avoidance cost ranged from 40 to 263 ∈/tCO_2 avoided (excluding transportation and storage costs), depending on the heat supply alternative used and the heat demand. Moreover, with a high cost for CO_2, CO_2 capture using excess heat could be a cost-effective alternative to reduce CO_2 emissions for oil refineries.
