Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil restoration customer, enabling them to increase manufacturing. The pump – a Mather & Platt BB5 – was greater than forty years outdated and had been topic to numerous post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of excessive pressure, high temperature steam to improve fluidity and permit the oil to be pumped to the surface. In order to boost extraction on this project, the customer wanted to extend water temperatures from 90° C to 140° C. However, there have been concerns that the present pump could not be capable of deliver this requirement. Nozzle loads were a particular concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most popular supplier of some 20 years, for help.
Mather & Platt is considered one of several heritage pump manufacturers for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering staff undertook a thorough 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 quantity of seal failures over time that had damaged the stuffing field and affected operational efficiency. There had also been เครื่องมือความดัน interventions for many years – however the pump had by no means 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 circumstances and with no common maintenance over such a long period of time. More importantly, it gave us confidence that a thorough overhaul may achieve the desired enchancment in performance, saving the customer the fee and misplaced manufacturing time that might be associated with sourcing and installing 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 element evaluation was undertaken to confirm that the nozzle masses would stand up to the specified temperature enhance. As a end result, the pump is now able to delivering steam at the higher temperatures required. The seal upgrades ensure it meets the most recent specs.
Concludes Mike Golds: “We are really pleased with the end result of the SAGD pump upgrade. It has not solely achieved the specified production enhance for the shopper, but in addition provided a extra sustainable and cost-effective solution than whole pump substitute. Using fashionable engineering and analysis, we now have been capable of give the prevailing pump a model new lease of life and ensure it’ll proceed to perform well for lots of extra years.”
