Abstract: A carbonator reactor includes a cylindrical body, a nozzle for supplying a gas stream, inside the carbonator reactor and above the surface of a liquid phase and where the nozzle is located at the top of the reactor body, an inlet, an outlet, means for regulating the temperature and the pressure, a stirring system and at least one baffle regulating the stirring of the liquid phase and the mass transfer of the gas into the liquid surface, at least one impeller having inclined blades that make an angle from 5° to 60° with respect to the vertical axis. The reactor prepares sodium carbonate and has a configuration for the mass transfer of a gas phase in a liquid phase. A method for the preparation of sodium carbonate by means of the carbonator reactor by capturing CO2 in an NaOH aqueous solution, directly on the free surface of the liquid phase.

Abstract: The present invention relates to a process for the manufacture of microporous carbon materials to perform selective separations of nitrogen in gas mixtures such as hydrogen sulfide, carbon dioxide, methane and C2, C3 and C4+ hydrocarbons, with high efficiency, shaped of microspheres or cylinders from copolymers of poly (vinylidene chloride-co-methyl acrylate) with density of 1.3 to 1.85 g/cm·sup·3 or poly (vinylidene chloride-co-vinyl chloride) with density of 1.3 to 1.85 g/cm.sup.3, using two stages. The first stage consists of a surface passivation of the material by chemical attack in a highly alkaline alcohol solution, with the aim of effecting a precarbonization on the surface of the copolymer that during the pyrolysis process is not deformed and gradually develops microporosity. The material of the first stage presents, in the layer, percentages between 55% to 85% carbon, between 5% to 20% oxygen, and between 10% to 40% chlorine.

Abstract: A wind turbine includes a rotor having a hub and at least one rotor blade, wherein the operating height of the hub is adjustable. Further, a method for operating a wind turbine is provided, which includes varying the height of the wind turbine.

Abstract: A method of assembling an offshore support system for use with a wind turbine. The method includes coupling a damper to a wind turbine tower. A counter-balance system is coupled to the damper for suspending at least a portion of the wind turbine above a water surface. The damper is positioned at least partially below a water surface to facilitate reducing movement of the wind turbine in at least one direction. The counter-balance system is positioned at least partially below the water surface to stabilize the wind turbine when subjected to wind and tidal forces.
