20110005452 | Buoyancy device and a method for stabilizing and controlling the lowering or raising of a structure between the surface and the bed of the sea - A method of using a buoyancy fluid presenting density that is less than that of sea water, and that is confined in a rigid or flexible leaktight casing, so as to constitute an immersed buoyancy element, wherein the buoyancy fluid is a compound that is naturally in a gaseous state at ambient atmospheric temperature and pressure, and in a liquid state at the underwater depth to which the buoyancy element is immersed. A method is also disclosed for placing a buoyancy element in place between the surface and the bed of the sea, wherein fluid is stored in a tank on a surface ship as a liquid in the cooled or compressed liquid state, and is injected in the liquid state into a pipe from the surface where it is stored to an immersed casing at an underwater depth at which the underwater pressure is not greater than the vapor pressure of the gas corresponding to the compound at the temperature at the depth. | 01-13-2011 |

20100116128 | Liquid/Gas Separation Device and Liquid/Gas Separation Method, in Particular for Crude Oil Liquid and Gaseous Phases - A liquid/gas separator device for separating the liquid and gaseous phases of a fluid, the device having first and second vertically-disposed elongate reservoirs. The first reservoir has a first bottom orifice connected to an arrival pipe for the fluid that includes a pressure-lowering device, at least one first top orifice, and a plurality of first intermediate orifices. The first reservoir is connected to a plurality of second reservoirs via a plurality of first transfer pipes, and via at least one second transfer pipe. Each of second reservoirs has a second top orifice connected to a common gas discharge pipe, and a second bottom orifice connected to a common degassed fluid discharge pipe. | 05-13-2010 |

20090152204 | Method and a Device for Separating a Multiphasic Liquid - The present invention relates to a cyclone type liquid/gas or liquid/liquid separator having separation properties that are stabilized, even when the flow rate and the proportions of the liquid phases for separation vary, by means of a platform situated in the low portion of a cylindrical separation chamber that is fed at its top end via a tangential feed orifice. The present invention also provides an installation and a method of separating the oil and water contained in crude oil, with the help of a cyclone of the invention. | 06-18-2009 |
20140116084 | Method for Liquefying Natural Gas with a Mixture of Coolant Gas - A method for liquefying a natural gas primarily including methane, preferably at least 85% of methane, the other components essentially including nitrogen and C2-C4 alkanes, in which the natural gas to be liquefied is liquefied by circulating at a pressure P0 no lower than the atmospheric pressure (Patm), P0 preferably being higher than the atmospheric pressure, in at least one cryogenic heat-exchanger (EC | 05-01-2014 |
20140190205 | Method For Liquefying Natural Gas With A Triple Closed Circuit Of Coolant Gas - A process for liquefying natural gas by; a) causing it to flow through three series connected heat exchangers, where gas is cooled to T | 07-10-2014 |
