Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil recovery customer, enabling them to extend production. The pump – a Mather & Platt BB5 – was greater than 40 years outdated and had been topic to quite a few post-installation alterations.
Heavy oil deposits are extremely viscous and require the injection of high stress, high temperature steam to enhance fluidity and allow the oil to be pumped to the surface. In order to spice up extraction on this venture, the shopper wanted to extend water temperatures from 90° C to 140° C. However, there have been issues that the present pump might not be succesful of deliver this requirement. เกจวัดแรงดันดิจิตอล were a specific concern. They turned to Celeros Flow Technology brand 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 provides full lifecycle support1. Their aftermarket engineering team undertook a thorough examination of the quadragenarian Steam Assisted Gravity Drainage (SAGD) boiler feed water pump used in the heavy oil extraction course of. The investigation revealed that the pump had suffered a number of seal failures over time that had damaged the stuffing box and affected operational efficiency. There had additionally been no maintenance 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 standard of the unique pump that it had continued to operate in such harsh conditions and with no regular maintenance over such a protracted time period. More importantly, it gave us confidence that a thorough overhaul may achieve the specified improvement in efficiency, saving the shopper the cost and misplaced manufacturing time that can be associated with sourcing and installing a brand 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 component evaluation was undertaken to confirm that the nozzle masses would withstand the desired temperature increase. As a outcome, the pump is now capable of delivering steam at the higher temperatures required. The seal upgrades ensure it meets the most recent specs.
Concludes Mike Golds: “We are actually happy with the result of the SAGD pump upgrade. It has not only achieved the desired production increase for the shopper, but also provided a extra sustainable and cost-effective answer than whole pump alternative. Using modern engineering and analysis, we’ve been capable of give the prevailing pump a new lease of life and ensure it’s going to proceed to perform nicely for many extra years.”
