Expert support on innovative C02 pumps for subsea oil and gas separation
Sulzer is collaborating with TechnipFMC in developing new subsea CO2 S
ulzer Flow Equipment has been selected by TechnipFMC to collaborate in developing new subsea CO2
pump solutions for new technologies. Petrobras’ advanced high pressure separation technology, HISEP, enables the separation of CO2
pump solutions
while reducing costs and emissions. Currently, the associated rich CO2
gas processed on FPSOs at topside needs to be treated and recompressed through large, energy-intensive compressors. Although this allows the CO2
gas to be reinjected in the -rich natural gas
from oil at the seabed. The process has the potential to provide significant gains in energy efficiency and productivity to floating production storage and offloading (FPSO) vessels
reservoir, it is highly energy intensive. The new pump technology will support and enable the gas stream, rich in CO2
, to be separated and pumped
immediately back into the reservoir at the seabed, 2,000m below the water
We are excited to work with
TechnipFMC and Petrobras to bring this remarkable new technology to life

line, allowing FPSOs to improve their efficiency and reduce their carbon footprint, further enhancing production.
LONGTERM COLLABORATION Sulzer Flow Equipment has been collaborating with TechnipFMC to develop and test supercritical CO2
pumps for Petrobras’ HISEP
technology since 2017. Following the staged development and validation of a prototype, the pump expert is now supplying three customised 6 MW high-pressure centrifugal (HPcp) pumps for Petrobras’ planned HISEP pilot project in the Brazilian pre-salt oil region. The HISEP technology is supported by Petrobras and its partners in the Libra Consortium. Upon delivery, the pumps will be tested and validated to the highest standards in a purpose-built laboratory at the Federal University of Itajuba.
