Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil recovery customer, 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 excessive pressure, high temperature steam to enhance fluidity and allow the oil to be pumped to the floor. In order to boost extraction on this venture, the shopper wanted to increase water temperatures from 90° C to 140° C. However, there have been concerns that the prevailing pump could not have the flexibility to ship this requirement. Nozzle hundreds had been a selected concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most popular supplier of some 20 years, for assistance.
Mather & Platt is one of several heritage pump manufacturers for which Celeros Flow Technology presents full lifecycle support1. Their aftermarket engineering group undertook a radical 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 box and affected operational effectivity. There had additionally been เครื่องมือวัดpressure interventions for many years – but the pump had by no means truly failed.
Says Mike Golds, Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testomony to the quality of the original pump that it had continued to operate in such harsh circumstances and with no regular maintenance over such an extended time frame. More importantly, it gave us confidence that a thorough overhaul may achieve the specified improvement in performance, saving the shopper the price 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 performance. In addition, finite element analysis was undertaken to substantiate that the nozzle loads would face up to the specified temperature enhance. As a outcome, the pump is now able to delivering steam on the greater temperatures required. The seal upgrades ensure it meets the latest specs.
Concludes Mike Golds: “We are actually pleased with the end result of the SAGD pump improve. It has not only achieved the specified manufacturing increase for the shopper, but in addition provided a more sustainable and cost-effective answer than total pump alternative. Using modern engineering and analysis, we have been capable of give the existing pump a model new lease of life and ensure it’ll proceed to carry out well for many extra years.”
