เพรสเชอร์เกจคือ has injected new life into a heritage pump for a Canadian heavy oil restoration buyer, enabling them to extend manufacturing. The pump – a Mather & Platt BB5 – was more than 40 years old 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 enhance fluidity and permit the oil to be pumped to the surface. In order to boost extraction on this project, the client needed to increase water temperatures from 90° C to 140° C. However, there have been considerations that the existing pump might not be in a position to ship this requirement. Nozzle loads were a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most well-liked provider of some 20 years, for help.
Mather & Platt is one of a number of 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 within the heavy oil extraction process. The investigation revealed that the pump had suffered a selection of seal failures over time that had damaged the stuffing box and affected operational efficiency. There had also been no upkeep interventions for many years – however the pump had never actually failed.
เกจวัดแรงดันภาษาอังกฤษ , 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 common upkeep over such an extended period of time. More importantly, it gave us confidence that a thorough overhaul could achieve the specified improvement in performance, saving the customer the fee and misplaced production time that could be associated with sourcing and installing a new unit.”
Celeros Flow Technology overhauled the SAGD pump and performed a mechanical seal upgrade and Plan 23 seal flush to optimize pump efficiency. In addition, finite element evaluation was undertaken to substantiate that the nozzle hundreds would withstand the specified temperature improve. As a end result, the pump is now capable of delivering steam at the larger temperatures required. The seal upgrades ensure it meets the latest specifications.
Concludes Mike Golds: “We are really happy with the result of the SAGD pump upgrade. It has not solely achieved the desired production increase for the customer, but in addition provided a more sustainable and cost-effective resolution than complete pump substitute. Using modern engineering and evaluation, we’ve been able to give the existing pump a model new lease of life and guarantee it will proceed to perform well for many extra years.”
