My 2009 post about ChevronTexaco’s Vacuum Resid Slurry Hydrocracking (VRSH) has
been so popular that I decided to search for more current news on the
process. One of the items appearing in

LC‐MAX and Other LC‐FINING Process Enhancements to Extend Conversion and
Onstream Factor
AFPM Annual Meeting, March 11-13, 2012,

Presented By:

Abstract
Recent process enhancements incorporated into our LC-FINING unit designs and
operating experience gained from recently
commissioned units have led to a new generation of plants with reduced
investment, improved energy efficiency, enhanced conversion capabilities and
improved unit on-stream factors. An example of such a unit is GS Caltex’s 60
kBPSD Vacuum Residue Hydrocracker, which was commissioned the 3rd quarter of
2010 just 42 months after the kick-off of the Basic Engineering Design. This
unit was able to achieve design throughput and conversion within 40 days of
introducing vacuum residue feed and has been able to realize an on-stream
factor of 94 percent over its first 18 months of operation, exceeding industry
norms by 4 percent. In addition to the extended conversion capabilities of our
LC-FINING process, Chevron Lummus Global has proceeded to develop the LC-MAX
process to further alleviate conversion constraints. LC-MAX combines LCFINING
and solvent deasphalting in an integrated hydroprocessing configuration,
enabling residue conversions of 85 volume percent to be attained, even when
processing very difficult high sediment forming opportunity crudes.
