Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration buyer, enabling them to increase manufacturing. The pump – a Mather & Platt BB5 – was greater than 40 years outdated and had been topic to quite a few post-installation alterations.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 stress, excessive temperature steam to enhance fluidity and allow the oil to be pumped to the floor. In order to boost extraction on this venture, the customer needed to increase water temperatures from 90° C to 140° C. However, there have been issues that the prevailing pump may not be ready to deliver 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 assistance.
Mather & Platt is one of several heritage pump brands for which Celeros Flow Technology offers full lifecycle support1. digital pressure gauge engineering staff undertook an intensive 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 numerous seal failures over time that had broken the stuffing box and affected operational effectivity. There had additionally been no maintenance interventions for decades – however 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 operate in such harsh situations and with no regular maintenance over such an extended period of time. More importantly, it gave us confidence that a thorough overhaul may obtain the desired improvement in efficiency, saving the customer the fee and lost production time that could be associated with sourcing and putting in a new unit.”
Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal upgrade and Plan 23 seal flush to optimize pump efficiency. In addition, finite component analysis was undertaken to verify that the nozzle masses would withstand the desired temperature improve. As a result, the pump is now capable of delivering steam at the higher temperatures required. The seal upgrades guarantee it meets the newest specifications.
Concludes Mike Golds: “We are really pleased with the outcome of the SAGD pump upgrade. It has not only achieved the desired manufacturing improve for the customer, but also provided a extra sustainable and cost-effective solution than total pump alternative. Using modern engineering and analysis, we now have been in a place to give the existing pump a model new lease of life and ensure it will continue to carry out properly for so much of more years.”
