Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil recovery customer, enabling them to increase production. The pump – a Mather & Platt BB5 – was more than forty years outdated and had been subject to quite a few post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of excessive stress, excessive temperature steam to improve fluidity and permit the oil to be pumped to the floor. 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 concerns that the existing pump may not have the ability to deliver this requirement. Nozzle masses had been a particular concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most popular provider of some 20 years, for help.
เพรสเชอร์เกจ & Platt is considered one of a quantity of heritage pump manufacturers for which Celeros Flow Technology offers full lifecycle support1. Their aftermarket engineering staff undertook an intensive examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used in the heavy oil extraction process. The investigation revealed that the pump had suffered a variety of seal failures over time that had damaged the stuffing box and affected operational effectivity. There had also been pressure gauge 10 bar interventions for decades – however 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 function in such harsh situations and with no common maintenance over such a protracted period of time. More importantly, it gave us confidence that a thorough overhaul might obtain the desired improvement in efficiency, saving the client the fee and misplaced manufacturing time that can be related to sourcing and putting in a new unit.”
Celeros Flow Technology overhauled the SAGD pump and carried out a mechanical seal upgrade 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 enhance. As a end result, the pump is now capable of delivering steam on the greater temperatures required. The seal upgrades ensure it meets the newest specifications.
Concludes Mike Golds: “We are really pleased with the outcome of the SAGD pump upgrade. It has not solely achieved the specified production improve for the customer, but in addition offered a more sustainable and cost-effective resolution than complete pump substitute. Using fashionable engineering and evaluation, we’ve been capable of give the prevailing pump a model new lease of life and guarantee it will proceed to carry out well for a lot of more years.”
