  • Method and device for the underwater testing of a filtration system
    Patent number: 10414673
    Abstract: A method for testing an underwater filtration system as well as the underwater testing device which enables the operation of filtration systems in aquatic conditions. The testing method includes introducing a flow of water into the underwater testing device via a water inlet, said underwater testing device including at least one filter, bringing said flow in the underwater testing device up to said filter, obtaining a filtrate downstream of said filter and discharging said filtrate into the environment via a discharge pipe. The underwater testing device is placed underwater at a depth of at least 500 meters.

  • SEAWATER TREATMENT METHOD FOR THE PRODUCTION OF INJECTION WATER FOR UNDERSEA OIL DRILLING AND CORRESPONDING INSTALLATION
    Publication number: 20100230366
    Abstract: A method for decreasing the dissolved oxygen content in water used for extracting oil from rocks includes directing water and gas into a housing containing at least one hydrophobic membrane such that the water contacts only a first surface of the membrane and the gas contacts only a second surface of the membrane. The pressure of the gas is decreased thereby causing the oxygen in the water to pass through the first side of the membrane to the second side of the membrane and mix with the gas. A system for decreasing the dissolved oxygen content in water used for extracting oil from rocks includes a plurality of membrane modules. Each module contains at least one hydrophobic membrane. A water supply inlet and a gas supply inlet direct water over the first and second surface respectively of each of the hydrophobic membranes. A water outlet and a gas outlet direct water and gas respectively out of the plurality of membrane modules.
