Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil recovery customer, enabling them to increase production. The pump – a Mather & Platt BB5 – was greater than 40 years previous and had been subject to numerous post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of excessive strain, excessive temperature steam to enhance fluidity and allow the oil to be pumped to the floor. In order to boost extraction on this project, the client wanted to extend water temperatures from 90° C to 140° C. However, there have been issues that the present pump may not be succesful of ship this requirement. Nozzle loads have been a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most well-liked supplier of some 20 years, for assistance.
Mather & Platt is considered one of several heritage pump manufacturers for which Celeros Flow Technology offers full lifecycle support1. Their aftermarket engineering staff 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 variety of seal failures over time that had broken the stuffing field and affected operational effectivity. There had also been no maintenance interventions for decades – however the pump had never really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testomony to the standard of the unique pump that it had continued to operate in such harsh situations and with no regular maintenance over such a long time period. More importantly, it gave us confidence that a thorough overhaul may achieve the specified improvement in performance, saving the client the fee and misplaced production 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 performance. In addition, finite component analysis was undertaken to substantiate that the nozzle hundreds would face up to the specified temperature increase. As a end result, the pump is now able to delivering steam on the larger temperatures required. The seal upgrades ensure it meets the latest specifications.
Concludes Mike Golds: “We are actually happy with the outcome of the SAGD pump improve. It has not solely achieved the desired manufacturing enhance for the customer, but also supplied a extra sustainable and cost-effective answer than complete pump replacement. Using เกจวัดแรงดันถังแก๊ส and analysis, we’ve been in a position to give the present pump a new lease of life and ensure it’s going to proceed to carry out properly for many more years.”
