Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration buyer, enabling them to increase production. The pump – a Mather & Platt BB5 – was more than forty years outdated and had been topic to quite a few post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of excessive 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 client needed to increase water temperatures from 90° C to 140° C. However, there have been considerations that the present pump might not be ready to ship this requirement. Nozzle loads were a specific 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 a number of heritage pump brands for which Celeros Flow Technology offers full lifecycle support1. Their aftermarket engineering group undertook a thorough examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used in the heavy oil extraction course of. ไดอะแฟรม ซีล revealed that the pump had suffered numerous seal failures over time that had damaged the stuffing box and affected operational efficiency. There had also been no maintenance interventions for decades – but 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 original pump that it had continued to function in such harsh conditions and with no regular maintenance over such a protracted period of time. More importantly, it gave us confidence that a thorough overhaul might obtain the specified improvement in efficiency, saving the shopper the price and lost production time that could be related to sourcing and putting in a model new unit.”
Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal upgrade and Plan 23 seal flush to optimize pump performance. In addition, finite component analysis was undertaken to verify that the nozzle hundreds would stand up to the specified temperature enhance. As a end result, the pump is now capable of delivering steam at the larger temperatures required. The seal upgrades guarantee it meets the latest specs.
Concludes Mike Golds: “We are really happy with the finish result of the SAGD pump upgrade. It has not solely achieved the specified production increase for the client, but also supplied a more sustainable and cost-effective solution than whole pump alternative. Using modern engineering and analysis, we now have been in a position to give the existing pump a new lease of life and guarantee it’ll continue to carry out properly for so much of extra years.”
