Patent number: 10107549Abstract: Process for liquefying natural gas in a cryogenic heat exchanger by flowing in indirect contact with refrigerant fluid entering heat exchanger at a first inlet at temperature T0 and pressure P1, and flowing through the exchanger as co-current with the natural gas stream, leaving the heat exchanger in the liquid state, then being expanded at the cold end of the exchanger to return to gaseous state at a pressure P?1 P1 and temperature T1 T0, before leaving the hot end of exchanger by outlet orifice in gaseous state T0. The fluid is then reliquefied to the inlet of the exchanger via compression followed by partial condensation and phase separation, a first liquid phase taken to the first inlet, a first gaseous portion compressed by a second compressor and cooled in desuperheater by contact with portion of the first liquid phase, prior to condensing in a second condenser.Type: GrantFiled: July 4, 2013Date of Patent: October 23, 2018Assignee: Saipem S.A.Inventors: Marc Bonnissel, Bertrand Du Parc, Boris Bolosier

Patent number: 8776706Abstract: 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.Type: GrantFiled: August 19, 2010Date of Patent: July 15, 2014Assignee: Salpem S.A.Inventors: Michel Baylot, Marc Bonnissel, Xavier Rocher
