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 The pump – a Mather & Platt BB5 – was more than 40 years outdated and had been subject to quite a few post-installation alterations.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 floor. In order to spice up extraction on this venture, the customer wanted to extend water temperatures from 90° C to 140° C. However, there were concerns that the existing pump may not have the power to ship this requirement. Nozzle hundreds were a specific concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred supplier of some 20 years, for help.
Mather & Platt is one of a quantity of heritage pump manufacturers for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering group 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 field and affected operational effectivity. There had additionally been no maintenance interventions for decades – but the pump had never really 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 operate in such harsh situations 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 efficiency, saving the shopper the price and misplaced production time that can be related to sourcing and putting in 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 performance. In addition, finite factor evaluation was undertaken to confirm that the nozzle loads would stand up to the specified temperature increase. As a outcome, the pump is now capable of delivering steam at the greater temperatures required. The seal upgrades guarantee it meets the most recent specs.
Concludes Mike Golds: “We are really happy with the outcome of the SAGD pump improve. It has not solely achieved the desired manufacturing increase for the customer, but in addition offered a more sustainable and cost-effective resolution than whole pump substitute. Using ราคาเกจวัดแรงดันลม and analysis, we now have been in a position to give the existing pump a model new lease of life and ensure it’s going to proceed to carry out properly for many extra years.”
