  • Publication number: 20230040153
    Abstract: The present disclosure relates to a novel improved method for continuous crystallization of highly crystalline clathrate hydrates. The novel improved method utilizes a novel hydrator capable of overcoming heat and mass transfer limitations that usually constrain crystallization rate and thus reduces process productivity. The disclosed method and hydrator are for production of crystalline clathrates in general, CO2 capture, capture of other clathrate forming compounds, CO2 storage and transportation, storage and transportation of any clathrate forming compound in a solid lattice, gas separation or water desalination or purification purposes.

  • Patent number: 11484862
    Abstract: A chemical reactor/mixer, in particular for producing hydrates comprising a mixer network plate and heat exchanger plates wherein the network mixer plate comprises an array of chambers that are connected by channels where the flow of one or more fluids is mixed and divide sequentially. The network mixer plate is confined by the heat exchanger plate that have an inner chamber where a heat exchanger fluid is introduced. Said network plates and heat exchanger plates are designed to have the option to be assembled as modules of larger processing units.

  • Patent number: 7708918
    Abstract: The present invention relates to a process and device RIM involving a mixing chamber (1) with opposing injectors (2, 3). The efficiency is maximized through the operation in flow regimes with very strong mixing dynamics, which is assured by means of the introduction of schemes to: detect the flow regime within the mixing chamber, through the dynamic pressure measurement upstream of the injectors (2, 3), using means (5); and/or impose a chaotic flow regime, through the pulsation of the opposed jets, using means (6). Alterations in design, comparatively to the traditional geometries, are also proposed, concerning: the mixing chamber (1), being foreseen a prismatic rectangular chamber; the injectors (2, 3), being foreseen elongated injectors; and even the scheme of injection of the materials, using a third injector (4).
