There is recent post Feb 3, 2009 about CVX putting its Commercial plant VRSH on hold under coker news section. <See – The news item is about coker updates on MRO Detroit, Garyville & CVX Pascagoula projects>.
It appears the economic conditions and chance to add more R&D advances to the process are reasons for hold on this plant.
As mentioned earlier – the background discussion around this process is also posted in earlier discussion on March 8, 2008 news post on CVX new Hvy Oil technology – VRSH that was hyped (over so?) to replace cokers.
