The latest report on base oil refining capacity in the United States shows changes at a number of plants in the past year and indicates that capacity for premium stocks now exceeds Group I. The most interesting number, however, is one that did not change: the capacity listed for Motivas plant at Port Arthur, Texas.
Officials acknowledged last year that Port Arthurs output grew after it changed catalyst material during a maintenance turnaround in the first quarter of 2004. Before that, the company said the plant was capable of making 22,000 barrels per day of Group II stocks. While Motiva did not publicly discuss the size of last years increase, sources outside the company have said that representatives pegged it between 10 and 20 percent.
