Clean, green, hydrocracking machine
Dan Torchia, Arun Arora and Luyen Vo of Chevron Lummus Global offer an overview of the hydrocracking technology advancements that provide creative ways to meet the clean fuels challenge.
Clean fuels from heavy feedstocks
Two innovative hydrocracking schemes for clean fuels production are presented.
Scheme one presents a modified TRSEC scheme to process refractory feeds such as HCGO and HVGO.  The objective is to maximize diesel with severe cold flow property specifications, along with providing the flexibility to produce feed for group III lube base oils production.
Scheme two presents CLG's latest patented scheme for residue hydrocracking called LC-MAX.  This technology will permit refiners to convert over 85% of the vacuum residue to VGOs and lighter material, even while processing the most difficult feeds.  The process is particularly attractive when a refiner has an existing delayed coking unit that requires debottlenecking or when tightening margins require the refiner to process opportunity crudes.
