Oil & gas: Full refurbishment for island refinery

摘要

After a refinery closed down its 50-year old plant, most of the rotating equipment suffered damage from exposure to the tropical climate. To restart the plant, the new owners called upon Hydro, Inc., to reverse engineer, rebuild and perform testing on their critical jet pump. The process of reopening the plant had uncovered more than 500 pumps that needed considerable refurbishment and repair. The most important of these was a critical jet pump used for hydraulic decoking. It was badly damaged and sent to the original equipment manufacturer (OEM) for inspection. The OEM recommended that the refinery replace most of the pump parts, as well as a costly repair that would require 35 weeks to rebuild. Viable alternative Instead, the refinery sent the pump to global aftermarket pump service provider, Hydro, Inc. in Chicago, where it was refurbished for just over half the cost of the OEM proposal. The time involved was also significantly improved to just eight weeks by using a non-destructive evaluation and rebuild process at a 46,000 ft~2 facility where Hydro develops and implements engineering modifications for improving the performance of critical pumps and then verifies that performance in their Hydraulic Institute certified test lab. Significant reopening. The original refinery opened in the mid 1960s. In the early 1970s, it was re-rated at 650,000 barrels per day. It had been one of the largest refineries in the western hemisphere, so the impact of reopening the plant would be significant. In this case, Hydro was tasked to work with the critical high-energy pump to prepare for its reopening. The new owners began the process two years ago and it is expected that the plant will be open for operation in the first quarter of 2020. Once restarted, the plant will be able to process up to 210,000 barrels per day of oil, a fraction of the 1,500-acre (607-hectare) plant's peak capacity in the 1970s of 650,000 bpd.
