![]() The first commercial unit was successfully commissioned at the Giant Industries refinery in Gallup, New Mexico, in 2003. The process was initially developed by Process Dynamics Inc and was acquired by DuPont in August 2007. The IsoTherming process from DuPont Sustainable Solutions is a commercially proven technology that enables refiners to meet their increased hydroprocessing objectives at significantly reduced capital and operating costs over conventional technologies. However, these investments must provide an acceptable long-term return on capital, while producing the desired product yields and qualities from cost-advantaged feedstocks such as FCC cycle oils, coker gas oils, shale oil and tar sands. One result of these challenges is the need for petroleum refiners to make significant investments to increase their hydroprocessing capabilities, either through unit debottlenecks or new unit construction. Today’s refiners are facing an unprecedented number of challenges: producing gasoline and diesel fuels to lower sulphur and increased combustion quality specifications more stringent environmental controls on emissions the need to process the lowest cost feedstocks such as heavier, sour crudes and cost escalation in capital projects
