Study theorizes use of geothermal sources for energy in refineries

02/11/2008
Geothermal sources for direct heating can theoretically serve as an alternative source of high-temperature (>130° C.) heat in processing plants.Cutting CO2 emissions from a refinery requires reducing the amount of fuel burned. Although CO2 savings was the motivating and initial goal of this study, the real economic incentive is savings in refinery fuel burned. We estimated this at roughly 6 times the value of CO2 emissions saved based on $15/ton CO2 and $68/bbl of crude.The upper sedimentary layer in the West Netherlands basin is not thermally or geomechanically interesting for creating a geothermal heat exchanger; however, the underlying deformed sediment layer and expected depth ...
