Parallel membrane elements are arranged in parallel within a pressure vessel. A sealing body is disposed within the pressure vessel and is compressed against an inner surface of the pressure vessel to provide a leak-right seal in between a feed gas side of the sealing body and a non-permeate side of the sealing body. The sealing body may be slid within the pressure vessel without damaging the sealing body and in all cases without requiring mechanical assistance.


Methods, burner, apparatuses, and systems are provided for controlling a velocity of a jet of gas exiting a burner when the gas is heated or not and at a corresponding second higher temperature or lower first temperature. Through the use of a temperature-sensitive magnetic valve, the flow of a gas can be redirected to maintain velocity of the gas as delivered to a combustion chamber based on the temperature of the gas. The temperature-sensitive magnetic valve can redirect flow of the gas based on the magnetic state of a ferromagnetic material. The state of the temperature-sensitive magnetic valve changes based on the temperature of the gas to maintain the velocity of the gas delivered through an outlet of the burner to the combustion chamber. Thus, heated gases and standard temperature gases can be delivered at approximately equal velocities thus maintaining flame size and shape.

The method according to the present invention allows heat treatment processes with a significantly reduced internal oxidation while allowing a broad choice of process gases for temperatures above the upper critical temperature (T_(U)).


A furnace for performing an endothermic process comprising tubes containing a catalyst for converting a gaseous feed, wherein tubes are positioned in rows inside the furnace, wherein burners are mounted between the tubes and between the tubes and the furnace walls parallel to the tubes row and wherein the burners rows and the tubes rows are ended by end walls and are divided into sections with the distance from the end burner to the end wall being B2W, the distance between two adjacent burners in the section being B2B, and half the distance in-between two sections being B2S, wherein the burners in the rows are arranged in such a way that the ratios B2B/B2W and B2B/B2S are greater than 1.3 thus limiting the occurrence of the flame merging phenomenon and reducing significantly the quadratic mean of the tube temperature profile.


Composite porous hydrophobic membranes are prepared by forming a perfluorohydrocarbon layer on the surface of a preformed porous polymeric substrate. The substrate can be formed from poly(aryl ether ketone) and a perfluorohydrocarbon layer can be chemically grafted to the surface of the substrate. The membranes can be utilized for a broad range of fluid separations, such as microfiltration, nanofiltration, ultrafiltration as membrane contactors for membrane distillation and for degassing and dewatering of fluids. The membranes can further contain a dense ultra-thin perfluorohydrocarbon layer superimposed on the porous poly(aryl ether ketone) substrate and can be utilized as membrane contactors or as gas separation membranes for natural gas treatment and gas dehydration.

Hydrogen Mobility Europe 2 (H2ME 2) brings together action in 8 European countries to address the innovations required to make the hydrogen mobility sector truly ready for market. The project will perform a large-scale market test of hydrogen refuelling infrastructure, passenger and commercial fuel cell electric vehicles operated in real-world customer applications and demonstrate the system benefits generated by using electrolytic hydrogen solutions in grid operations. H2ME 2 will increase the participation of European manufacturers into the hydrogen sector, and demonstrate new vehicles across a range of platforms, with increased choice: new cars (Honda, and Daimler), new vans (range extended vehicles from Renault/Symbio and Renault/Nissan/Intelligent Energy) and a new medium sized urban delivery truck (Renault Trucks/Symbio). H2ME 2 develops an attractive proposition around range extended vehicles and supports a major roll-out of 1,000 of these vehicles to customers in France, Germany, Scandinavia and the UK. 1,230 new hydrogen fuelled vehicles will be deployed in total, trebling the existing fuel cell fleet in Europe. H2ME 2 will establish the conditions under which electrolytic refuelling stations can play a beneficial role in the energy system, and demonstrate the acquisition of real revenues from provision of energy services for aggregated electrolyser-HRS systems at a MW scale in both the UK and France. This has the further implication of demonstrating viable opportunities for reducing the cost of hydrogen at the nozzle by providing valuable energy services without disrupting refuelling operations. H2ME 2 will test 20 new HRS rigorously at high level of utilisation using the large vehicle deployment. The loading of stations by the end of the project is expected to average 20% of their daily fuelling capacity, with some stations exceeding 50% or more. This will test the HRS to a much greater extent than has been the case in previous projects.
