Axens VGO hydrotreating and Mild hydrocracking technologies are well established with over 60 units licensed worldwide.
VGO hydrotreating provides some remarkable improvements in FCC operations thanks to hydrogen addition in hydrotreated VGO. Mild hydrocracking increases the VGO conversion to 20%-60% and produce middle distillates along with hydrotreated VGO. VGO hydrotreating and Mild hydrocracking units are operated under relatively mild conditions and producing naphtha, diesel as well as VGO feed to downstream cracking unit.
Depending on unit severity, the diesel cut may require further hydrotreatment. Due to its aromatics and organic-nitrogen contents, it is more refractory to additional hydrotreating than straight-run diesel. This has led to the commercialization of the HyC-10 process, which meets the ULSD challenge.
