Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil recovery buyer, enabling them to extend production. The pump – a Mather & Platt BB5 – was greater than forty years outdated and had been subject to quite a few post-installation alterations.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 boost extraction on this challenge, the shopper 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. Nozzle masses had been a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred provider of some 20 years, for help.
เกจวัดแก๊ส & Platt is considered one of a number of heritage pump manufacturers for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering team undertook a radical 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 number of seal failures over time that had broken the stuffing field and affected operational efficiency. There had additionally been no maintenance interventions for decades – but 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 function in such harsh situations and with no common maintenance over such a protracted period of time. More importantly, it gave us confidence that a thorough overhaul could obtain the desired improvement in efficiency, saving the shopper the cost and lost manufacturing time that could be associated with sourcing and putting in a model new unit.”
Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal improve and Plan 23 seal flush to optimize pump performance. In addition, finite element analysis was undertaken to verify that the nozzle masses would stand up to the desired temperature improve. As a end result, the pump is now capable of delivering steam on the higher temperatures required. The seal upgrades ensure it meets the latest specifications.
Concludes Mike Golds: “We are really pleased with the end result of the SAGD pump upgrade. It has not solely achieved the specified production enhance for the client, but additionally provided a more sustainable and cost-effective answer than whole pump substitute. Using modern engineering and analysis, we now have been able to give the present pump a model new lease of life and guarantee it’s going to proceed to carry out properly for many more years.”
