Abstract: The present invention relates to a device comprising an (i) electrolysis cell comprising (ia) a negative electrode compartment for the reduction of water (H2O) into dihydrogen (H2) and (ib) a supercapacitive flow compartment as a positive electrode compartment, wherein said electrolysis cell is in fluidic communication with a carbonation reactor. The present invention also relates to a process comprising the production of dihydrogen (H2) by electrolysis and applications thereof.

Abstract: A static fluid mixer includes a cylindrical flow conduit and at least two inclined, axially spaced, and circumferentially offset internal baffle members for creating counter-rotating vortices in fluids passing through the conduit. The baffle members each have upstream edges spaced from an inner surface of the conduit by a first distance less than a radius of the conduit and downstream edges that are spaced from the inner surface of conduit by a second distance that is greater than the first distance. The baffle members can each have a trapezoidal shape with the downstream edge being smaller in length than the upstream edge thereof.

Abstract: A method for mixing one or more fluid streams or for mixing solid particles with one or more fluid streams involves flowing the materials to be mixed through a static fluid mixer. The mixer includes an elongated fluid flow conduit having a centrally located longitudinally extending axis and an inner generally cylindrical wall extending around said axis and defining a fluid flow path within the conduit which extends along the central axis of the conduit. The mixer also includes at least two circumferentially offset internal baffle members designed to create countery-rotating vortices in fluids passing through the conduit. The first baffle is in the form of an elongated inclined plate positioned in said fluid flow path at a first location in said conduit. This baffle plate has an upstream end, a downstream end and a longitudinal axis.
