Celeros Flow Technology injects new life into forty 12 months old SAGD pump to extend heavy oil production for customer

Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil restoration customer, enabling them to extend manufacturing. The pump – a Mather & Platt BB5 – was more than forty years old 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 enhance fluidity and permit the oil to be pumped to the floor. In order to spice up extraction on this project, the shopper needed to increase water temperatures from 90° C to 140° C. However, there have been considerations that the present pump could not be capable of deliver this requirement. Nozzle loads have been a particular concern. Odd turned to Celeros Flow Technology model ClydeUnion Pumps, their most popular provider of some 20 years, for assistance.
Mather & Platt is certainly one of several heritage pump manufacturers for which Celeros Flow Technology offers full lifecycle support1. Their aftermarket engineering group undertook a thorough 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 number of seal failures over time that had broken the stuffing box and affected operational efficiency. There had additionally been no maintenance interventions for decades – 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 standard of the unique pump that it had continued to function in such harsh conditions and with no regular maintenance over such a long time period. More importantly, it gave us confidence that a thorough overhaul might obtain the specified improvement in efficiency, saving the customer the fee and lost manufacturing time that can be associated with sourcing and putting in a brand 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 component analysis was undertaken to substantiate that the nozzle loads would face up to the specified temperature increase. As a result, the pump is now capable of delivering steam on the larger temperatures required. The seal upgrades ensure it meets the latest specs.
Concludes Mike Golds: “We are actually pleased with the result of the SAGD pump improve. It has not solely achieved the specified manufacturing increase for the client, but in addition offered a more sustainable and cost-effective solution than whole pump replacement. Using modern engineering and analysis, we now have been able to give the prevailing pump a new lease of life and ensure it’s going to proceed to carry out properly for many more years.”
