Celeros Flow Technology has injected new life right 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 The pump – a Mather & Platt BB5 – was more than forty years outdated and had been subject to numerous post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of high pressure, excessive 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 shopper needed to extend water temperatures from 90° C to 140° C. However, there were considerations that the existing pump may not have the power to deliver this requirement. Nozzle loads were a selected concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most popular provider of some 20 years, for help.
Mather & Platt is certainly one of several 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 within the heavy oil extraction course of. ไดอะแฟรม ซีล 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 also been no maintenance interventions for decades – however 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 standard of the unique pump that it had continued to operate in such harsh circumstances and with no regular upkeep over such a long time period. More importantly, it gave us confidence that a thorough overhaul could achieve the desired improvement in efficiency, saving the client the cost and misplaced manufacturing time that might be associated with sourcing and installing 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 element analysis was undertaken to confirm that the nozzle loads would stand up to the desired temperature increase. As a outcome, the pump is now capable of delivering steam on the higher temperatures required. The seal upgrades guarantee it meets the latest specs.
Concludes Mike Golds: “We are really happy with the result of the SAGD pump improve. It has not solely achieved the desired production increase for the shopper, but also provided a extra sustainable and cost-effective answer than complete pump substitute. Using trendy engineering and evaluation, we have been capable of give the present pump a brand new lease of life and ensure it’s going to continue to carry out well for lots of more years.”
