Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil restoration customer, enabling them to extend manufacturing. The pump – a Mather & Platt BB5 – was greater than 40 years outdated and had been subject to numerous post-installation alterations.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 enhance fluidity and allow the oil to be pumped to the surface. In order to spice up extraction on this project, the client wanted to extend 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 hundreds were a particular concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most popular supplier of some 20 years, for help.
Mather & Platt is certainly one of a number of heritage pump manufacturers for which Celeros Flow Technology provides 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 number of seal failures over time that had damaged the stuffing box and affected operational efficiency. There had also been เกจ์ลมsumo interventions for many years – but the pump had never really 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 conditions and with no common upkeep over such a protracted period of time. More importantly, it gave us confidence that a thorough overhaul might obtain the specified improvement in efficiency, saving the customer the cost and misplaced production time that could be related to sourcing and installing a 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 loads would stand up to the specified temperature increase. As a outcome, 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 outcome of the SAGD pump upgrade. It has not solely achieved the desired manufacturing improve for the customer, but also provided a extra sustainable and cost-effective resolution than total pump replacement. Using modern engineering and evaluation, we now have been capable of give the prevailing pump a model new lease of life and guarantee it’s going to proceed to perform nicely for so much of more years.”
