เกจวัดแรงดันไนโตรเจน has injected new life into a heritage pump for a Canadian heavy oil restoration customer, enabling them to increase production. The pump – a Mather & Platt BB5 – was greater than 40 years old and had been topic 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 surface. In order to boost 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 may not be capable of deliver this requirement. Nozzle masses were a selected concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their preferred supplier of some 20 years, for assistance.
Mather & Platt is certainly one of several heritage pump brands for which Celeros Flow Technology presents 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 numerous seal failures over time that had broken the stuffing box and affected operational effectivity. There had also been no maintenance interventions for decades – however the pump had by no means really 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 function in such harsh circumstances and with no regular maintenance over such a long 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 lost manufacturing time that may be associated with sourcing and putting in a model 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 confirm that the nozzle hundreds would face up to the desired temperature improve. As a result, the pump is now able to delivering steam on the greater temperatures required. The seal upgrades guarantee it meets the newest specs.
Concludes Mike Golds: “We are actually pleased with the outcome of the SAGD pump improve. It has not only achieved the desired manufacturing enhance for the client, but in addition supplied a extra sustainable and cost-effective resolution than total pump substitute. Using modern engineering and evaluation, we’ve been in a place to give the existing pump a brand new lease of life and ensure it will continue to carry out well for lots of more years.”
