摘要:
The present invention provides a process and an apparatus for the production of compressed hydrogen gas from an input stream comprising gaseous methane. The apparatus comprises a solid oxide fuel (1) cell and an electrochemical device (2) capable of extracting gaseous hydrogen and compressing it. The solid oxide fuel cell is capable of reforming the input stream comprising gaseous methane (6) to produce a product mixture comprising hydrogen. At least a portion of the product mixture comprising hydrogen is supplied (10) to the electrochemical device to produce a compressed hydrogen stream (11). At least a portion of the product mixture comprising hydrogen is consumed by the solid oxide fuel cell to produce direct current electricity to at least partially power the electrochemical device, and optionally an electrolysis apparatus (12), for additional hydrogen production.

The disclosure relates to a method and system for treating ballast water and ballast water treatment systems in order for treatment effects to be carried out, such as controlling the transportation of undesirable and invasive marine organisms. In particular, the disclosure relates to methods and systems for applying a superimposed time-varying frequency electromagnetic wave comprising both AC and DC components in a pulsating manner to ballast water within a ballast water treatment system.
摘要:
An ion generating element (10) has at least one first discharger (12) for generating positive ions and at least one second discharger (13) for generating negative ions, both fitted or printed on a single dielectric member (11). The first and second dischargers (12) and (13) are each composed of a pair of a first or second discharging electrode (12a) or (13a), respectively, formed on the surface of the dielectric member (11) and a first or second induction electrode (12b) or (13b), respectively, buried in the dielectric member (11), and are arranged both on the same flat surface of the dielectric member (11) but separately from and independently of each other. This construction helps to alleviate the neutralization among the generated ions themselves, thus to effectively release both positive and negative ions, and thereby to enhance the ion generation efficiency.
摘要:
Die vorliegende Erfindung betrifft ein Verfahren sowie eine Einrichtung zur Energieerzeugung aus wasserstoffreichem Industrie-Abgas, insbesondere aus Anlagen der Halbleiterfertigung und/oder Halbleiterprozessierung. Bei dem Verfahren wird das Abgas durch eine Stromerzeugungs-Einrichtung mit wenigstens einem Kompressor (2) und einer oder mehreren Brennstoffzellen (3) geleitet. In der Stromerzeugungs-Einrichtung wird das Abgas komprimiert und aus wenigstens einem Teil des darin enthaltenen Wasserstoffs Strom erzeugt. Der Kompressor (2) ist dabei mit dem Ausgang der AbgasAnlage verbunden, wobei der Eingangsdruck des Kompressors (2) auf einen Sollwert geregelt wird. Mit dem Verfahren und der zugehörigen Einrichtung lässt sich der im wasserstoffhaltigen Industrie-Abgas enthaltene Energiegehalt des Wasserstoffs wenigstens zum Teil in elektrische Nutzenergie wandeln. Das Verfahren und die Einrichtung lassen sich dabei insbesondere für die Rückverstromung des Industrie-Abgases von Anlagen der Halbleiterfertigung und/oder - prozessierung ohne Rückwirkung auf diese Prozesse einsetzen.

The invention relates to a gas flow cleaning device (100) comprising a corona electrode (102) provided with corona tips (102A), a non-corona electrode (104) with a cylinder axis (104B). The corona electrode is centrally positioned in the cylindrical non-corona electrode. The cylindrical non-corona electrode (104) comprises a circumferential wall section (402B) with a multitude of openings. The corona electrode comprises a cylindrical array of corona tips. The gas flow cleaning device further comprises a gas flow generator (106) configured to generate a gas flow through the cylindrical non-corona electrode along the corona electrode.
摘要:
An air inert gas generating system consists of heat exchangers, a heating element, and a plurality of solid oxide electrochemical gas separator (SOEGS) cells (2). The SOEGS cells (2) are interconnected in series to create a stack (14A). A voltage is applied to the stack causing oxygen ions to be transported from the air flowing through the cathode through the electrolyte (8) to the anode side of the SOEGS, resulting in oxygen-depleted gas. The oxygen-depleted gas can be used to inert the ullage of aircraft fuel tank or support the fire suppression system in the cargo hold. The oxygen-enriched gas can be used for other purposes.
