Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration customer, enabling them to extend production. The pump – a Mather & Platt BB5 – was greater than forty years outdated and had been subject to quite a few post-installation alterations.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 extremely viscous and require the injection of high stress, excessive temperature steam to improve fluidity and permit the oil to be pumped to the surface. In order to boost extraction on this venture, the shopper wanted to increase water temperatures from 90° C to 140° C. However, there were concerns that the existing pump may not be in a position to ship this requirement. Nozzle masses have been a specific concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred supplier of some 20 years, for assistance.
Mather & Platt is certainly one of several heritage pump manufacturers for which Celeros Flow Technology provides full lifecycle support1. Their aftermarket engineering group undertook an intensive examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used in the heavy oil extraction process. เกจอาร์กอน revealed that the pump had suffered numerous seal failures over time that had broken the stuffing field and affected operational efficiency. There had also been no maintenance interventions for many years – but the pump had never actually failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testomony to the standard of the unique pump that it had continued to function in such harsh conditions and with no common maintenance over such an extended period of time. More importantly, it gave us confidence that a thorough overhaul may obtain the specified enchancment in efficiency, saving the shopper the price and lost manufacturing time that could be related to sourcing and putting in a 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 component evaluation was undertaken to confirm that the nozzle loads would withstand the desired temperature increase. As a end result, the pump is now able to delivering steam on the greater temperatures required. The seal upgrades ensure it meets the newest specifications.
Concludes Mike Golds: “We are actually pleased with the end result of the SAGD pump improve. It has not solely achieved the desired production enhance for the client, but in addition provided a more sustainable and cost-effective solution than complete pump substitute. Using modern engineering and evaluation, we’ve been able to give the present pump a new lease of life and ensure it’ll continue to carry out properly for a lot of more years.”
