The Roaring Twenties<\/h2>\n\n\n\n

Roxana Petroleum was renamed Shell Petroleum (Roxana’s products were always marketed under the Shell label). Shell’s midwestern headquarters moved into the new Shell Building in downtown St. Louis. Automobile usage grew rapidly and to meet the demand new refining processes were developed to convert heavier compounds in crude oil into gasoline. Shell gambled on a thermal cracking process patented by C. P. (Carbon Petroleum) Dubbs with the very first two Dubbs Units being built at WRR in 1921. After initial difficulties with Dubbs Unit no. 1 (including an explosion), the process proved successful and six additional units were constructed. An asphalt plant was started up. Refinery capacity in 1921 was 45,000 barrels per day.<\/p>\n<\/div><\/div>\n\n\n\n
