Abstract: An apparatus for accelerated dissolution of carbonates with buffered pH. The apparatus includes a mixer, a dissolution reactor and a pH correction reactor. The mixer includes: a chamber; a water supply; a carbonic gas supply; and a carbonate supply. Water, carbonic gas and carbonate are provided to the chamber in predetermined continuous flow rates to obtain a design flow rate of lean mixture at the outlet. The dissolution reactor includes a duct connected to the chamber receiving the lean mixture and allowing at least partial dissolution of the carbonate which transforms the lean mixture into an ionic mixture according to the reaction CaCO3+CO2+H2O? Ca(HCO3)2. The pH correction reactor comprises a duct and a hydroxide supply. The mixture is then released into the sea. Embodiments also relate to a method for the accelerated dissolution of carbonates with buffered pH for the permanent sequestration of CO2 in the sea in the form of bicarbonates.

Abstract: A plant and a method for producing decarbonized oxide or hydroxide using carbonate, water and electric power. The plant includes an electric calciner, a contactor, a pH correction apparatus, and a dosing device. The plant is adapted to receive at the inlet electric power, carbonate and water, and to release at the outlet decarbonized oxide or hydroxide and a buffered ionic mixture rich in bicarbonates, which, once released into the sea, represents the permanent storage for CO2. The plant uses the bicarbonates as permanent CO2 storage in the sea: this storage allows a CO2 storage at low costs and in modular plants.

Abstract: A plant and a method for the production of hydrogen and bicarbonate. The plant includes a gasifier, a reformer, a direct contact exchanger and an apparatus for the production of bicarbonate. The plant is suitable for receiving fuel, oxygen, water, carbonate, brine at the inlet and for producing hydrogen, bicarbonate and calcium chloride at the outlet. The plant uses a self-cleaning direct contact heat exchanger to cool the syngas downstream of the reformer and to produce the superheated steam that feeds the gasifier: this heat exchanger allows the production of hydrogen at low costs and in modular plants.

Abstract: An insert (8) for a screw (1) or crown (1?) cap for the closure of bottles (10) is described, the said cap (1, 1?) including a body (2) and the insert (8) being designed to be fixed to the body facing the interior of the bottle (10) when the cap (1, 1?) is closed over the said bottle. The insert (8) comprises a sealing element (9) capable of being compressed in one part between the body and a portion of the bottle (10) when the cap (1, 1?) is closed over the bottle, as well as a permeating element (16, 109, 209), connected to the sealing element, impermeable to liquids and having a permeability to oxygen measured at 20° C. of between 10?6 and 10?10 (Ncm3*cm/cm2*cmHg*s), which is designed to close a passage made in the said cap between the inside and outside of the bottle, in order to control the flow of oxygen between the inside and outside of the bottle.

Abstract: System for butt jointing a first and at least one second photovoltaic module for creating a roof-covering, each module has a panel with photovoltaic cells and a support frame having at least one longitudinal end profile and at least one longitudinal side profile. At least one longitudinal support profile is provided at least for the longitudinal end profile of the frame of the first module, and for the longitudinal end profile of the frame of the second module. The longitudinal end profile in each module has a box-section longitudinal body fixable to the longitudinal side profile, a first longitudinal wing delimiting a seat for engaging the panel, and at least one second longitudinal wing having an arched longitudinal surface for engaging the support profile.

Abstract: A plant (100) for the gasification of biomass comprises a gasifier (10) and an apparatus (23) for the filtration of the gas. The apparatus comprises a scrubber (31), a tank (41), and a wet electrostatic precipitator (51).
