TechnipFMC plc is collaborating with Sulzer Circulate Tools to develop new subsea carbon dioxide (CO2) pump options.
TechnipFMC is creating and testing supercritical CO2 pumps for Petróleo Brasileiro S.A. (Petrobras), particularly for the Brazilian vitality main’s HISEP know-how. Sulzer stated in a information launch that it has been collaborating with TechnipFMC for the pumps since 2017.
Following the staged improvement and validation of a prototype, Sulzer is supplying three custom-made 6-megawatt high-pressure centrifugal (HPcp) pumps for Petrobras’ deliberate HISEP pilot venture within the Brazilian pre-salt oil area. The HISEP know-how is supported by Petrobras and its companions within the Libra Consortium. Upon supply, the pumps can be examined and validated to the very best requirements in a purpose-built laboratory on the Federal College of Itajuba, in keeping with the discharge.
Petrobras’ high-pressure separation know-how, HISEP, permits the separation of CO2-rich pure fuel from oil on the seabed. The method has the potential to offer vital good points in vitality effectivity and productiveness to floating manufacturing storage and offloading (FPSO) vessels whereas lowering prices and emissions, the discharge said.
At the moment, the related wealthy CO2 fuel processed on FPSOs at topside must be handled and recompressed by massive, energy-intensive compressors. Whereas this enables the CO2 fuel to be reinjected into the reservoir, it’s extremely energy-intensive.
Sulzer stated the brand new pump know-how will assist and allow the fuel stream to be separated and pumped instantly again into the reservoir on the seabed, 6561.7 toes (2000 meters) beneath the water line, permitting FPSOs to enhance their effectivity and cut back their carbon footprint, additional enhancing manufacturing.
“We’re excited to work with TechnipFMC and Petrobras to convey this exceptional new know-how to life,” Sulzer Head of the Circulate Tools Vitality and Infrastructure Enterprise Unit Jonathan Lloyd stated.
“By avoiding the necessity to course of CO2 on the FPSO, this collaboration permits vital vitality effectivity and topside house benefits. The venture underscores Sulzer’s long-term heritage and dedication to innovation, cementing it as a pacesetter in new pump know-how, in addition to its worth in shut partnerships to drive cleaner, extra environment friendly and worthwhile development,” Lloyd remarked.
“With the HISEP venture, we are going to once more display how our management in subsea processing, know-how innovation, and built-in options can ship actual and sustainable advantages to our companions,” Luana Duffe, Government Vice President for New Vitality at TechnipFMC, stated. “Sulzer is an skilled in market-leading pump options for the trade’s most demanding processes and is a go-to accomplice for the Mero 3 HISEP® venture. This venture has actually been a shared journey of innovation for all of us”.
Petrobras’ HISEP venture can be deployed on the Mero 3 improvement within the Brazilian pre-salt oil area, the place fields usually comprise a 50/50 mixture of oil and CO2-rich fuel. Petrobras operates the Mero unitized area with a 38.6 p.c stake. Its consortium companions are Shell Brasil, with a 19.3 p.c stake; TotalEnergies, with 19.3 p.c; CNOOC with 9.65 p.c; CNPC with 9.65 p.c; and Pré-Sal Petróleo S.A. with 3.5 p.c.
Mero is the third largest area in Brazil by way of quantity of oil in place, behind solely Tupi and Búzios, additionally positioned within the pre-salt Santos Basin. Along with the Duque de Caixas FPSO, Petrobras stated it plans to place one other unit into operation in Mero in 2025.
