The article http://www.coking.com/Forum/tm.asp?m=833 shows four of Five California Bay area refineries are boosting production and upgrading – two of these Valero & Tesoro have fluid cokers. Tesoro is replacing its fluid coker with delayed cokers to increase their ability to process heavy crude. Although Valero is increasing both the amount of crude and the percentage of heavy crude it has not indicated adding either coker capacity or asphalt capacity to handle the extra bottoms. All but the Chevron Richmond refinery already have cokers (& ConocoPhillips has two since the Rodeo complex now includes both the Rodeo & Santa Maria refinery & cokers).
The states of California, Louisiana & Texas together have the largest concentration of refineries (~43%) and cokers (~58%) in the US.
Tesoro canceled its other coker addition project in Anacortes, WA and ConocoPhillips put its Ferndale, WA coker on hold in mid 2006 when project cost increased at both sites by over $100 million due to all US construction demands & materials price increase. Both have moved forward with other coking projects like Tesoro Martinez which also incurred sizeable cost increase for the projects. ConocoPhillips will be starting up its new Borger & Woodriver coker additions in May 2007 and the recent ConocoPhillips Joint Venture with EnCana Heavy Canadian Crude projects is expected to add another stage of coker expansions to both COP sites in future (+2010).
