Celeros Flow Technology has injected new life into a heritage pump for a Canadian heavy oil recovery buyer, enabling them to increase production. The pump – a Mather & Platt BB5 – was more 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 stress, excessive 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 increase water temperatures from 90° C to 140° C. However, there were considerations that the existing pump may not have the flexibility to deliver this requirement. Nozzle masses had been a particular concern. They turned to Celeros Flow Technology brand ClydeUnion Pumps, their most popular supplier of some 20 years, for assistance.
Mather & Platt is considered one of a number of heritage pump brands for which Celeros Flow Technology offers 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 course of. The investigation revealed that the pump had suffered numerous seal failures over time that had damaged 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.
weksler ea14 , Global Upgrade and Rerate Programme Manager for ClydeUnion Pumps: “It is testament to the quality of the original pump that it had continued to operate in such harsh situations and with no common maintenance over such an extended period of time. More importantly, it gave us confidence that a thorough overhaul may obtain the specified improvement in efficiency, saving the shopper the price and lost production time that can be associated with sourcing and putting in a model 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 evaluation was undertaken to substantiate that the nozzle loads would withstand the specified temperature improve. As a outcome, the pump is now capable of delivering steam on the larger temperatures required. The seal upgrades ensure it meets the latest specifications.
Concludes เครื่องมือที่ใช้วัดความดัน : “We are really pleased with the result of the SAGD pump improve. It has not only achieved the specified manufacturing increase for the customer, but also supplied a more sustainable and cost-effective solution than whole pump alternative. Using modern engineering and analysis, we have been capable of give the existing pump a brand new lease of life and ensure it’ll continue to carry out well for lots of extra years.”
