Celeros Flow Technology has injected new life right into a heritage pump for a Canadian heavy oil recovery customer, enabling them to extend manufacturing. The pump – a Mather & Platt BB5 – was greater than forty years previous and had been topic to quite a few post-installation alterations.
Heavy oil deposits are extraordinarily viscous and require the injection of excessive pressure, excessive temperature steam to improve fluidity and allow the oil to be pumped to the surface. In order to spice up extraction on this challenge, the client needed to extend water temperatures from 90° C to 140° C. However, there have been issues that the present pump might not be capable of deliver this requirement. Nozzle loads had been a specific concern. They turned to Celeros Flow Technology model ClydeUnion Pumps, their most well-liked provider of some 20 years, for help.
Mather & Platt is one of several heritage pump brands for which Celeros Flow Technology offers full lifecycle support1. เกจวัดแรงดันน้ำ engineering group 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 broken the stuffing box and affected operational efficiency. There had additionally been no upkeep interventions for decades – but 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 standard of the unique pump that it had continued to operate in such harsh conditions and with no regular maintenance over such a long time frame. More importantly, it gave us confidence that a thorough overhaul might achieve the specified improvement in efficiency, saving the customer the fee and misplaced manufacturing time that might be related to 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 withstand 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 latest specs.
Concludes Mike Golds: “We are really happy with the outcome of the SAGD pump improve. It has not solely achieved the desired production increase for the customer, but additionally offered a extra sustainable and cost-effective solution than complete pump replacement. Using modern engineering and analysis, we now have been in a position to give the present pump a new lease of life and ensure it’s going to proceed to carry out well for lots of extra years.”
