Abstract:
A module (10) and an apparatus (1) incorporating such module utilizing a plurality of tubular membrane elements (14, 16), each configured to separate oxygen from an oxygen containing feed stream when an electric potential difference is applied to induce oxygen ion transport in an electrolyte thereof. The tubular membrane elements can be arranged in a bundle that is held in place by end insulating members (18, 20). The insulating members can be positioned within opposed openings (108,110)of end walls (104,106)of a heated enclosure (12) and can incorporate bores to allow an oxygen containing feed stream to flow past exposed ends of the tubular membrane elements for cooling the end seals of such elements. Further, first and second manifolds (22, 24) can be provided in a module in accordance with the present invention to collect separated oxygen from two separate portions of the tubular membrane elements.
Abstract:
The invention relates to pure hydrogen membrane extraction from hydrogen-containing gas mixtures. The aim of said invention is to increase the performance and service life of membranes. The inventive flat sealed filtering element comprises two walls, a separating porous element arranged therebetween and a hydrogen-removing pipe. The walls consist of water permeable membranes made of a palladium alloy and sealingly connected to each other in frames. The wall membrane is shaped in the form of the relief consisting of protrusions and recesses, which are uniformly distributed along the working surface thereof. The ratio between the protrusion length (L) in a normal cross-section and the projection (D) thereof ranges from 1.05 to 1+d, wherein d is the membrane material plasticity. The relief makes it possible to increase the strength, reliability, service life and the performance of the membrane due to the modification of the surface area and thickness thereof. The membrane device comprises a body, a set of parallel filtering elements, gas supplying and gas removing elements, which enable an initial mixture to flow from the periphery to the center, a weak mixture to be discharged from the membrane center, prevent the formation of dead zones and make it possible to attain the maximum degree of hydrogen extraction.
Abstract:
A compact hydrogen purification module capable of affording high-grade purified hydrogen, easy assembly and easy control of size is disclosed. The module includes a plurality of unit cells. Each of the unit cells includes two metal membranes permeable only by hydrogen, a metal support ring attached between the metal membranes by diffusion bonding to support the metal membranes, and having a radial hole to allow hydrogen to flow therethrough, a porous plate disposed between the metal membranes to allow the hydrogen to flow therethrough, and a fitting coupled to the metal support ring and having a hole communicating with the hole of the metal support ring to allow the hydrogen to flow therethrough. The individual fittings are connected to each other so that hydrogen collected in the individual fittings is discharged through a hydrogen product line.
Abstract:
Die Erfindung betrifft ein Membrantrennverfahren und eine Membrananlage zur energieeffizienten Sauerstofferzeugung unter Verwendung gemischt leitender keramischer Membranen. Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit anzugeben, sodass unter Vermeidung der Nachteile des Standes der Technik die Energieeffizienz des MIEC-Membranverfahrens zur Sauerstoffproduktion, insbesondere mit autarken MIEC-Membrananlagen, wesentlich gesteigert wird. Erfindungsgemäß wird die Aufgabe mit einem Membrantrennverfahren zur energieeffizienten Gewinnung von Sauerstoff aus erwärmter Frischluft unter Verwendung gemischt leitender Membranen im Vakuumbetrieb, wobei die Frischluft nach Trennung des Sauerstoffs als Abluft abgeführt wird, dadurch gelöst, dass mindestens 85 % der zur Erwärmung der Frischluft erforderlichen Wärmeenergie durch Nutzung der Abwärme der Abluft und / oder des gewonnenen Sauerstoffs erfolgt, dass die restliche Erwärmung der Frischluft durch externe Energiezufuhr realisiert wird und dass das Verhältnis von Frischluft zu erzeugtem Sauerstoff im Normalbetrieb innerhalb der Grenzen 6:1 und 25:1 eingestellt wird.
