Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil recovery customer, enabling them to extend manufacturing. The pump – a Mather & Platt BB5 – was more than forty years old and had been topic to numerous post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of high pressure, high temperature steam to improve fluidity and permit the oil to be pumped to the floor. In order to boost extraction on this project, the client needed to extend water temperatures from 90° C to 140° C. However, there were issues that the prevailing pump could not be capable of deliver this requirement. Nozzle masses were a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most well-liked provider of some 20 years, for help.
Mather & Platt is certainly one of a number of heritage pump manufacturers for which Celeros Flow Technology offers full lifecycle support1. Their aftermarket engineering team undertook a radical examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used in the heavy oil extraction course of. The investigation revealed that the pump had suffered numerous seal failures over time that had damaged the stuffing box and affected operational effectivity. There had additionally been no maintenance interventions for decades – but the pump had by no means really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testament to the standard of the unique pump that it had continued to function in such harsh situations and with no regular maintenance over such a long time period. More importantly, it gave us confidence that a thorough overhaul may achieve the desired improvement in performance, saving the customer the cost and misplaced manufacturing time that could 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 efficiency. In addition, finite component analysis was undertaken to substantiate that the nozzle masses would face up to the desired temperature enhance. As a outcome, the pump is now able to delivering steam on the larger temperatures required. The seal upgrades guarantee it meets the newest specs.
Concludes Mike Golds: “We are really pleased with the result of the SAGD pump upgrade. It has not solely achieved the specified manufacturing increase for the client, but also offered a more sustainable and cost-effective resolution than total pump substitute. Using pressure gauge ดิจิตอล and analysis, we have been in a position to give the prevailing pump a new lease of life and guarantee it’ll continue to perform nicely for many extra years.”
