Just in case you are wondering – BP Lima is the oldest operating refinery in US. Its sister refinery BP Toledo is the second oldest operating refinery and Husky (former BP) Whiting refinery had first coker in 1929.
All these older BP Padd 4 refineries were part of Original Standard Oil before it split into the 7 sisters which became majors like BP.
The Whiting coker was developed in 1916 -1930 using Bronson process and became first delayed coker installed refinery. Prior to 1916 the crude stills were shutdown and coke mined from bottom of stills/towers. The fluid coking process didnt come along until 1953.
