Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil recovery customer, enabling them to increase production. The pump – a Mather & Platt BB5 – was greater than forty years old and had been topic to numerous post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of excessive stress, excessive temperature steam to improve fluidity and permit the oil to be pumped to the surface. In order to spice up extraction on this challenge, the customer needed to increase water temperatures from 90° C to 140° C. However, there have been issues that the existing pump might not be able to ship this requirement. Nozzle loads have been a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most well-liked provider of some 20 years, for assistance.
Mather & Platt is certainly one of several heritage pump manufacturers for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering group undertook a thorough examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used within the heavy oil extraction course of. The investigation revealed that the pump had suffered numerous seal failures over time that had broken the stuffing box and affected operational effectivity. There had also been no maintenance interventions for decades – however the pump had never actually failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testomony to the quality of the unique pump that it had continued to function in such harsh conditions and with no regular upkeep over such a protracted period of time. More importantly, it gave us confidence that a thorough overhaul may obtain the desired enchancment in performance, saving the client the price and misplaced production time that could be associated with sourcing and installing a new unit.”
Celeros Flow Technology overhauled the SAGD pump and carried out a mechanical seal improve and Plan 23 seal flush to optimize pump efficiency. In addition, finite element evaluation was undertaken to confirm that the nozzle hundreds would withstand the specified temperature increase. As a outcome, the pump is now able to delivering steam at the higher temperatures required. The seal upgrades ensure it meets the most recent specs.
Concludes Mike Golds: “We are actually pleased with the finish result of the SAGD pump improve. เกจวัดแรงดูด has not only achieved the desired production improve for the customer, but in addition provided a more sustainable and cost-effective solution than total pump replacement. Using trendy engineering and evaluation, we have been capable of give the existing pump a model new lease of life and guarantee it’s going to proceed to perform nicely for lots of more years.”
