Case Studies & Innovations

A refinery had contracted EIS to perform a debottleneck study, including FEED and detailed design, of their current operation to increase distillate rate in their MIDW unit from 3TBD to 3.5TBD. In addition, they wanted to improve reliability by going from a two feed pump operation with no spare to using one feed pump with an online spare.

A Cavity Water Collection Tank sustained substantial damage. The roof had become completely detached and the shell to floor joint was broken at several locations. EIS was tasked to determine if overpressure or deflagration was responsible and identify root cause.

An EIS client was scheduled to replace a 654,515 lb and 160 ft tall tower during a turnaround and was concerned about its structural integrity during the lift. Corrosion had reduced the wall thickness at several locations, and years of operation had caused the tower to deform and accumulate additional weight. EIS was requested to complete a Finite Element Analysis (FEA) in order to safely perform the lift.

A client was nearing completion of a newly constructed production unit at their facility. An established mechanical integrity/inspection program was in place at the plant. Based on our knowledge and expertise in these programs, the client selected EIS to complete the circuitization of these assets and related tasks.
