Auxiliary applicationsThe complex processes performed on a typical FPSO rely on the performance of dozens of pumps handling a variety of liquids under widely varying process conditions.
Brine re-injection pumpThe brine re-injection pump re-injects the low enthalpy reject brine back to the geothermal field to renew the available resources.
Heat transfer fluid pumpHeat transfer fluid pump (HTF) pumps circulate thermal oil through the parabolic troughs to heat it up and pump it to the solar steam generator. The main characteristics of the HTF pumps are their high temperature and their double sealing system. Depending on the plant size, HTF pumps can be either double or end suction type.
Hydraulic power recovery turbineMany industries aim to reduce their ecological footprint by minimizing energy consumption. Sulzer Hydraulic Power Recovery Reaction Turbines can be used to capture lost energy.
RO-island HPPThis is the heart of the SWRO Desalination process, where the desalination effect takes place. The Treated sea water is fed by means of the High Pressure pumps into the RO membranes, obtaining permeate or product water and high pressure brine rejection, whose high pressure energy is recovered by selected Energy Recovery Device.
Seawater treatmentWith enhanced oil recovery methods, often prior to injection sea water needs to be treated to remove or reduce salt content. Sulzer’s pumps achieve this by delivering sea water to the SRU / SWRO membrane racks.
