The present process invention in continuation to the U.S. Ser. No. 14/392,066 appertains to Advanced Combustion in post-combustion carbon capture, wherein the CO.sub.2-containing flue gas, said CO2-Stream, is cleaned from harmful constituents, recirculated, oxygenized and employed for combustion for the fossil fuels, referred to Flue Gas Oxy-Fueling in order to obtain a CO.sub.2-rich gas upstream to CO2-CC with significantly less gas flow rate subject to further processing. This continuation process patent also presents processing to prepare a CO.sub.2-rich CO2-Stream for the pre-combustion carbon capture downstream of gasification and gas cleaning process; or from the secondary CO2-Stream that stems from the cathodic syngas [CO/2H.sub.2] downstream of HPLTE-SG of patent parent, then downstream of the HP/IP-water shift converters in [CO.sub.2/3H.sub.2] composition, whereas the CO.sub.2-rich CO2-Stream from either pre-combustion process is routed to the CO2-CC for CO.sub.2 cooling and condensation section of the U.S. Ser. No. 14/392,066 to obtain liquid carbon dioxide for re-use as new fossil energy resource.

An electrolytic cell has a partition that covers an upper region of one electrode of an anode and a cathode in order to separate a gas generated from the anode and a gas generated from the cathode from each other. The partition has wall surfaces that are each opposite a surface of the electrode. The wall surfaces have, in lower end-side regions thereof, ribs extending in a direction that has a lateral direction component. The ribs and the partition are made of a fluororesin and are integrally formed.

Electrodes for use within an ozone generator and method for assembling and using the same.

The present invention relates to an oxygen generator integrated with an ozone removal filter such that an ozone removal filter is provided in an oxygen discharge opening communicating with an oxygen discharge hole of a water electrolytic cell constituting an apparatus for producing oxygen by using mineral water among generally used water, for filtering ozone generated with oxygen during electrolysis of water and ozone compounds, in which ozone is combined with various organic and inorganic materials contained in mineral water, such as calcium (Ca), magnesium (Mg) and silicon (Si), and thus the oxygen generator allows only high purity oxygen to pass through and to be discharged through the oxygen discharge hole.

An electrolytic cell includes a housing, a first diaphragm, a first electrode, a second electrode, and a first discharge port. The housing held an electrolyte solution. The first diaphragm partitions the interior of the housing into a first cell and a second cell. The first electrode is provided inside the first cell. The first electrode includes a first surface facing the first diaphragm, a second surface different from the first surface, and a first hole. The second electrode is provided inside the second cell adjacent to the first diaphragm. The second electrode includes a third surface adjacent to the first diaphragm, a fourth surface different from the third surface, and a second hole. The first discharge port discharges the electrolyte solution from the second cell. The first cell is configured to supply the electrolyte solution supplied therein to the third surface side of the second cell.

Electroplating results can be improved by dynamically controlling the pressure in different parts of an electroplating apparatus. For example, a number of plating problems can be avoided by ensuring that the pressure in an anode chamber always remains slightly above the pressure in an ionically resistive element manifold, both during electroplating and during non-electroplating operations. This pressure differential prevents the membrane from stretching downward into the anode chamber.

Provided are electrochemical cells for hydrogen production and methods for hydrogen production. The electrochemical cell and methods use a mediator that may have a reversible redox potential lying outside the onset of the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER). Also, provided are systems for generating hydrogen and water from oxygen and generating water from oxygen and hydrogen.

Various embodiments may include a method of electrochemical production of synthesis gas comprising: reducing carbon dioxide to a first product gas including carbon monoxide in a carbon dioxide electrolysis cell; splitting water to generate a second product gas including hydrogen in a water electrolysis cell; delivering at least one catholyte from the group consisting of: a first catholyte from the carbon dioxide electrolysis cell and a second catholyte from the water electrolysis cell, into a gas scrubbing apparatus; and removing non-reduced carbon dioxide from the first product gas in the gas scrubbing apparatus using the at least one catholyte as an absorbent.

Certain configurations of a gas chromatography system comprising an internal gas generator are described. In some instances, the gas chromatography system may comprise an internal hydrogen generator to provide hydrogen gas to a chromatography column for separation of analyte species. In certain examples, the gas chromatography system can be operated without any external gas inputs.

The present invention provides a chlorine dioxide manufacturing device that can accurately control the amount of chlorine dioxide produced. The present invention provides a chlorine dioxide gas manufacturing device comprising an electrolysis chamber, a liquid surface level measuring chamber, and a bubbling gas feeding device. The electrolysis chamber and the liquid surface level measuring chamber each comprises an electrolytic solution and a gas and the electrolysis chamber and the liquid surface level measuring chamber are joined to each other above each liquid surface via a gas piping and joined to each other below each liquid surface via an electrolytic solution piping so that the height of the electrolytic solutions contained in each chamber are substantially equal.
