Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil restoration customer, enabling them to increase production. The pump – a Mather & Platt BB5 – was greater than forty years previous and had been subject to quite a few post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of excessive stress, excessive temperature steam to improve fluidity and permit the oil to be pumped to the surface. In pressure gauge 10 bar to spice up extraction on this challenge, the shopper wanted to extend water temperatures from 90° C to 140° C. However, there were considerations that the present pump could not be capable of ship this requirement. Nozzle loads had been a specific concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most well-liked provider of some 20 years, for help.
Mather & Platt is considered one of several heritage pump manufacturers for which Celeros Flow Technology provides full lifecycle support1. Their aftermarket engineering team undertook a thorough 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 a selection 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 – 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 unique pump that it had continued to function in such harsh circumstances and with no common upkeep over such a protracted time frame. More importantly, it gave us confidence that a thorough overhaul may achieve the specified enchancment in performance, saving the shopper the cost and lost production time that can be related to 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 confirm that the nozzle hundreds would stand up to the desired temperature increase. As a end result, the pump is now able to delivering steam at the greater temperatures required. The seal upgrades ensure it meets the newest specifications.
Concludes Mike Golds: “We are actually happy with the result of the SAGD pump upgrade. It has not only achieved the desired production enhance for the customer, but also offered a more sustainable and cost-effective answer than total pump substitute. Using fashionable engineering and evaluation, we have been capable of give the prevailing pump a brand new lease of life and ensure it’s going to continue to perform well for many more years.”
