Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration buyer, enabling them to extend production. The pump – a Mather & Platt BB5 – was greater than forty years outdated and had been subject to numerous post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of high stress, high temperature steam to enhance fluidity and permit the oil to be pumped to the floor. In order to spice up extraction on this venture, the client needed to extend water temperatures from 90° C to 140° C. However, there have been considerations that the present pump could not be able to deliver this requirement. Nozzle masses were a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred provider of some 20 years, for assistance.
Mather & Platt is certainly one of several heritage pump manufacturers for which Celeros Flow Technology provides 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 a selection of seal failures over time that had broken the stuffing box and affected operational effectivity. There had also 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 testament to the standard of the unique pump that it had continued to operate in such harsh conditions and with no common upkeep over such an extended period of time. More importantly, it gave us confidence that a thorough overhaul may achieve the specified improvement in efficiency, saving the customer the price and misplaced manufacturing time that can be associated with sourcing and putting in a new unit.”
Celeros Flow Technology overhauled the SAGD pump and performed 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 masses would withstand the specified temperature enhance. As a result, the pump is now capable of delivering steam on the higher temperatures required. The seal upgrades ensure it meets the latest specs.
Concludes Mike Golds: “We are really happy with the finish result of the SAGD pump improve. It has not solely achieved the specified manufacturing improve for the client, but in addition supplied a more sustainable and cost-effective answer than total pump replacement. Using เกจวัดแรงดันแก๊สlpg and evaluation, we have been capable of give the prevailing pump a brand new lease of life and ensure it’s going to continue to carry out nicely for many extra years.”
