Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil recovery customer, enabling them to increase manufacturing. The pump – a Mather & Platt BB5 – was greater than forty years previous and had been subject to quite a few post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of excessive stress, high temperature steam to enhance fluidity and allow the oil to be pumped to the surface. In order to spice up extraction on this challenge, the client wanted to extend water temperatures from 90° C to 140° C. However, there have been considerations that the present pump could not be capable of ship this requirement. Nozzle masses were a selected 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 a number of heritage pump manufacturers for which Celeros Flow Technology provides full lifecycle support1. Their aftermarket engineering group 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 a quantity of seal failures over time that had damaged the stuffing field and affected operational effectivity. There had additionally been no maintenance interventions for many years – however the pump had never actually 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 function in such harsh circumstances and with no common upkeep over such an extended period of time. More importantly, it gave us confidence that a thorough overhaul could achieve the specified improvement in efficiency, saving the customer the fee and misplaced manufacturing time that could be related to sourcing and installing a brand 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 เกจวัดแรงดันไฟฟ้า , finite element analysis was undertaken to substantiate that the nozzle masses would face up to the desired temperature improve. As a result, the pump is now capable of delivering steam at the higher temperatures required. The seal upgrades guarantee it meets the newest specs.
Concludes Mike Golds: “We are really happy with the outcome of the SAGD pump improve. It has not solely achieved the desired production improve for the customer, but in addition offered a extra sustainable and cost-effective resolution than complete pump replacement. Using modern engineering and analysis, we have been able to give the present pump a brand new lease of life and guarantee it will proceed to perform nicely for lots of extra years.”
