Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration 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 The pump – a Mather & Platt BB5 – was more than forty years outdated and had been subject to numerous post-installation alterations.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 excessive stress, excessive temperature steam to improve fluidity and allow the oil to be pumped to the surface. In order to spice up extraction on this venture, the customer wanted to increase water temperatures from 90° C to 140° C. However, there were pressure gauge ด้าน ดูด that the existing pump might not be able to ship this requirement. Nozzle loads had been a specific concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred supplier of some 20 years, for assistance.
Mather & Platt is considered one of a quantity of heritage pump brands for which Celeros Flow Technology provides full lifecycle support1. Their aftermarket engineering staff undertook a thorough examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used in the heavy oil extraction process. The investigation revealed that the pump had suffered numerous seal failures over time that had broken the stuffing field and affected operational effectivity. There had also been no upkeep interventions for decades – but the pump had by no means really failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testomony to the quality of the original pump that it had continued to function in such harsh situations and with no regular upkeep over such an extended period of time. More importantly, it gave us confidence that a thorough overhaul could achieve the specified improvement in performance, saving the client the price and misplaced production time that can be related to 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 evaluation was undertaken to verify that the nozzle masses would stand up to the desired temperature enhance. As a end result, the pump is now able to delivering steam on the greater temperatures required. The seal upgrades ensure it meets the most recent specs.
Concludes Mike Golds: “We are actually happy with the outcome of the SAGD pump improve. It has not only achieved the desired manufacturing increase for the shopper, but additionally supplied a more sustainable and cost-effective answer than total pump replacement. Using trendy engineering and analysis, we have been capable of give the prevailing pump a new lease of life and guarantee it’ll proceed to carry out nicely for many more years.”
