Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil recovery buyer, enabling them to extend manufacturing. The pump – a Mather & Platt BB5 – was more than 40 years old and had been subject to numerous post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of excessive stress, excessive temperature steam to enhance fluidity and permit the oil to be pumped to the surface. In order to spice up extraction on this challenge, the shopper wanted to increase water temperatures from 90° C to 140° C. However, there have been concerns that the prevailing pump may not be ready to deliver this requirement. Nozzle loads were a specific 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 brands for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering staff undertook an intensive examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used within 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 efficiency. There had also been no upkeep interventions for many years – 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 quality of the unique pump that it had continued to operate in such harsh circumstances 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 specified enchancment in efficiency, saving the client the cost and misplaced production time that can be associated with sourcing and installing a model new unit.”
Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal improve and Plan 23 seal flush to optimize pump efficiency. In addition, finite factor evaluation was undertaken to verify that the nozzle masses would withstand the desired temperature enhance. As a result, the pump is now capable of delivering steam on the higher temperatures required. The seal upgrades ensure it meets the newest specifications.
Concludes diaphragm seal : “We are actually happy with the result of the SAGD pump upgrade. It has not only achieved the desired production increase for the shopper, but in addition offered a more sustainable and cost-effective answer than total pump replacement. Using trendy engineering and evaluation, we’ve been in a position to give the prevailing pump a model new lease of life and ensure it’ll continue to perform properly for many more years.”
