    摘要: A water stream is treated to remove oxygen before injecting the water into an underground hydrocarbon reservoir. The water-oxygen mixture is separated by centrifugal action using fixed spin blades (20). Oxygen is removed from the center of the conduit through a gas pipe (30) coupled to a vacuum pump (50). Nitrogen may be introduced upstream of the centrifuge to dilute the water-gas solution to improve the efficiency of the gas-liquid separation.

    摘要: Water that is produced during offshore hydrocarbon processing, such as hot produced water accompanying hydrocarbons taken from subsea reservoirs, or cold water resulting from heating LNG (liquified natural gas) to convert it to gas, is changed in temperature to be closer to that of the surrounding sea using apparatus of minimal cost. The apparatus includes a mixer tube (52) that lies totally submerged in the sea and a nozzle (54) that receives the produced water and that has a nozzle end (76) lying in a middle portion of the mixer tube. A location of the mixer tube middle portion at the nozzle end has an inside diameter (A) much larger than the nozzle end outside diameter (B) to induce the through flow of sea water from the surrounding sea through the mixer tube. The produced water is pumped to a high enough pressure to create turbulence in the mixer tube immediately downstream of the nozzle end to better mix the produced and sea waters.
