Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil recovery customer, enabling them to increase production. The pump – a Mather & Platt BB5 – was more than forty years previous and had been topic to quite a few post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of high pressure, excessive temperature steam to improve fluidity and allow the oil to be pumped to the surface. In order to boost extraction on this challenge, the shopper wanted to increase water temperatures from 90° C to 140° C. However, there have been issues that the prevailing pump might not be in a position to deliver this requirement. Nozzle masses had been a specific concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most well-liked provider of some 20 years, for help.
Mather & Platt is considered one of a number of heritage pump brands for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering team undertook a radical 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 a number of seal failures over time that had broken the stuffing field and affected operational effectivity. There had also been no maintenance interventions for decades – however the pump had never really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testament to the quality of the unique pump that it had continued to operate in such harsh circumstances and with no common upkeep over such a long period of time. More importantly, it gave us confidence that a thorough overhaul could achieve the specified improvement in efficiency, saving the shopper the cost and lost production time that can be associated with sourcing and installing a new unit.”
Celeros Flow Technology overhauled the SAGD pump and carried out a mechanical seal upgrade and Plan 23 seal flush to optimize pump efficiency. In addition, finite element analysis was undertaken to verify that the nozzle loads would withstand the specified temperature increase. As a outcome, 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 finish result of the SAGD pump improve. เพรสเชอร์เกจลม has not solely achieved the desired production enhance for the shopper, but in addition provided a extra sustainable and cost-effective answer than total pump alternative. Using trendy engineering and evaluation, we have been capable of give the existing pump a new lease of life and ensure it’s going to proceed to carry out properly for many more years.”
