  • Patent number: 10515426
    Abstract: A method of estimating a characteristic (Qn?, Q1?) of a load of liquefied natural gas being transported by a tanker at any point on a route (401, P; 501, 502, 503), the method being characterized in that the estimation is made by integrating, over the route (410, 411, 412, 420; 510, 511, 512) from a reference point (400, P; 500) at which said characteristic is known (Qn, Ql), a relationship associating the instantaneous transformation of the load with instantaneous navigation conditions.

  • Patent number: 9957452
    Abstract: A method for treating a synthesis gas from a gasification step. The synthesis gas is cooled to condense heavy organic impurities and water. At the end of the cooling step, light organic impurities and inorganic impurities are adsorped by at least one adsorption bed. The water and heavy tars are separated by decantation from the step of cooling the synthesis gas. At least one adsorption bed is regenerated by temperature-modulated or pressure-modulated desorption.

  • Patent number: 9815621
    Abstract: An installation for the in-port storage of liquid fuel, which is formed near a dock, is formed of at least an upper surface substantially parallel to the free surface of the sea and a frontal surface adjacent to the upper surface and partially immersed. The installation includes at least one module having a floating caisson containing a fluidtight tank that may contain liquid fuel and having a closed contour formed of an upper face, a lower face, and several lateral faces. The module is fixed to the dock by anchoring means connecting one of the lateral faces of the caisson to the frontal surface of the dock, the lower face and the lateral faces of the caisson therefore being at least partially immersed.
