A major EPC firm selected Rishabh to provide pipe stress analyses for a large Louisiana refinery processing 250,000 barrels per day to produce gasoline, jet-A aviation fuel, low-sulfur diesel, and anode grade coke.
The project’s 100 systems included a heavy naphtha stripper hydrocracker unit operating at 120 psig and 600° F, a main fractionator operating at 120 psig and 700° F, the catalytic cracking unit, the alkylation unit, and connected piping systems. The 100,000 feet of piping ranged up to 36 inches in diameter. The project involved 180 pieces of equipment and 52 load case combinations.
The brownfield project faced a tight schedule, resource constraints, and challenges due to space restrictions and existing structures. The contractor also required three major revisions in basic layouts plus frequent changes in specifications. The project required strict adherence to international standards, plus seamless and clear communication with the client.
