Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil recovery customer, enabling them to extend production. The pump – a Mather & Platt BB5 – was more than 40 years old and had been subject to numerous post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of excessive pressure, high temperature steam to improve fluidity and permit the oil to be pumped to the surface. In order to boost extraction on this venture, the customer wanted to increase water temperatures from 90° C to 140° C. However, there have been considerations that the prevailing pump might not have the flexibility to ship this requirement. เกจวัดแรงดันsumo had been a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most popular supplier of some 20 years, for help.
Mather & Platt is certainly one of several heritage pump brands for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering staff undertook an intensive examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used within 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 also been no maintenance interventions for decades – however the pump had by no means actually failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testament to the quality of the original pump that it had continued to operate in such harsh circumstances and with no common upkeep over such a long time frame. More importantly, it gave us confidence that a thorough overhaul could obtain the specified enchancment in performance, saving the shopper the cost and lost manufacturing time that might 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 component evaluation was undertaken to confirm that the nozzle hundreds would stand up to the desired temperature increase. As a end result, the pump is now capable of delivering steam on the larger temperatures required. The seal upgrades ensure it meets the latest specs.
Concludes Mike Golds: “We are really happy with the end result of the SAGD pump improve. It has not solely achieved the desired manufacturing enhance for the customer, but additionally provided a extra sustainable and cost-effective resolution than complete pump substitute. Using modern engineering and analysis, we have been in a position to give the prevailing pump a model new lease of life and ensure it’ll proceed to carry out well for many more years.”
