Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil recovery buyer, enabling them to increase manufacturing. The pump – a Mather & Platt BB5 – was more than 40 years previous and had been subject to numerous post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of high 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 challenge, the customer wanted to increase water temperatures from 90° C to 140° C. However, there have been considerations that the prevailing pump might not be ready to ship this requirement. Nozzle loads have been a particular concern. เครื่องมือวัดความดันคือ turned to Celeros Flow Technology model ClydeUnion Pumps, their most popular provider of some 20 years, for help.
Mather & Platt is certainly one of a quantity of heritage pump manufacturers for which Celeros Flow Technology provides full lifecycle support1. Their aftermarket engineering group 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 quantity of seal failures over time that had broken the stuffing field and affected operational effectivity. There had also been no upkeep interventions for decades – but the pump had never 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 circumstances 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 desired improvement in performance, saving the client the fee and misplaced production time that may be associated with sourcing and putting in a 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 element analysis was undertaken to substantiate that the nozzle masses would face up to the desired temperature increase. As a result, the pump is now capable of delivering steam at the larger temperatures required. The seal upgrades ensure it meets the latest specs.
Concludes Mike Golds: “We are really happy with the finish result of the SAGD pump improve. It has not only achieved the specified manufacturing improve for the customer, but also offered a extra sustainable and cost-effective answer than whole pump replacement. Using fashionable engineering and analysis, we have been capable of give the prevailing pump a new lease of life and guarantee it will proceed to carry out nicely for many extra years.”
