เกจวัดแรงดัน has injected new life into a heritage pump for a Canadian heavy oil recovery buyer, enabling them to extend manufacturing. The pump – a Mather & Platt BB5 – was greater than forty years outdated and had been subject to quite a few post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of excessive strain, excessive temperature steam to enhance fluidity and permit the oil to be pumped to the surface. In diaphragm seal to spice up extraction on this challenge, the client needed to increase water temperatures from 90° C to 140° C. However, there were issues that the present pump could not have the ability to deliver this requirement. Nozzle loads were a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred provider of some 20 years, for help.
Mather & Platt is one of several heritage pump manufacturers for which Celeros Flow Technology offers full lifecycle support1. Their aftermarket engineering staff undertook an intensive examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used in the heavy oil extraction process. The investigation revealed that the pump had suffered numerous seal failures over time that had broken the stuffing box and affected operational efficiency. There had additionally been no maintenance interventions for decades – but the pump had by no means really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testament to the standard of the original pump that it had continued to operate in such harsh conditions and with no common maintenance over such a long time period. More importantly, it gave us confidence that a thorough overhaul could achieve the desired improvement in efficiency, saving the shopper the cost and misplaced production time that can be related to sourcing and putting in a model new unit.”
Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal upgrade and Plan 23 seal flush to optimize pump performance. In addition, finite element evaluation was undertaken to confirm that the nozzle masses would stand up to the specified temperature improve. As a outcome, the pump is now capable of delivering steam at the higher temperatures required. The seal upgrades guarantee it meets the most recent specifications.
Concludes Mike Golds: “We are really happy with the end result of the SAGD pump improve. It has not solely achieved the desired production increase for the client, but in addition supplied a more sustainable and cost-effective solution than whole pump alternative. Using modern engineering and analysis, we have been able to give the present pump a model new lease of life and guarantee it’s going to continue to perform well for lots of more years.”
