Abstract: A method of producing methanol using a membrane gas absorption unit and at least one reactor. To produce methanol, a membrane gas absorption unit and a reactor are provided, each membrane gas absorption unit having a plurality of membranes, and each reactor having at least one section having a flocculator producing a pulsated magnetic field. The membrane gas absorption unit is first used to capture CO2 from a desired source. The captured CO2 is then supplied in a liquid form to the reactor. A hydrogen is supplied to the same reactor, and both captured CO2 and the hydrogen are then subjected to the pulsated magnetic field within the reactor to obtain a mixture of water and methanol. Finally, the water is distilled from the methanol to obtain pure methanol.

Abstract: A chemical reactor unit is provided that includes first and second circulation loops and an anode arranged between the first and second circulation loops. A first cathode is located at a beginning of the first circulation loop and a second cathode is located at an end of the second circulation loop. The chemical reactor unit can be used to generate a chlorine dioxide solution. A method for generating a chlorine dioxide solution includes applying a voltage differential between first and second cathodes and an anode arranged therebetween and pumping a fluid mixture comprising sodium chlorite and oxalic acid to sequentially pass the first cathode, the anode, and the second cathode. An apparatus is additional provided that includes a tank configured to hold a fluid mixture, a chemical reactor unit, and a pump configured to circulate the fluid mixture between the tank and the chemical reactor unit.
