Embodiments disclosed herein describe gas extraction devices and methods, and in particular disclose a helium extraction system. An example device includes a containment tank having an input portion and an output portion, wherein the input portion is configured to connect to a source gas transmission line for receiving a source gas stream and the output portion is configured to connect to the source gas transmission line for exhausting remaining components of the source gas stream after extraction of helium. The example device further includes a membrane that is permeable to helium and substantially impermeable to other gas components of the source gas stream, and a cooling system configured to modulate a temperature of the membrane. The device further includes a vacuum cell surrounding the membrane, and a compression system configured to reduce the pressure within the vacuum cell and extract gas from the vacuum cell, and a storage tank.

B&A: 4053.022PCT1 KAUST: 2014-099-02 26 ABSTRACT Embodiments provide a method of storing a compound using a metal organic framework (MOF). The method includes contacting one or more MOFs with a fluid and sorbing one or more compounds, such as O2 and CH4. O2 and CH4 can be sorbed simultaneously or in series. The metal organic framework can be an M-soc-MOF, wherein M can include aluminum, iron, gallium, indium, vanadium, chromium, titanium, or scandium.

A vessel system with means for catalyst protection during safety interlock trips or shut-down comprises a reactor (R), an inlet line (i) for a process gas, a sulfur guard (S), at least one adsorption vessel (A) containing an adsorbent selective for adsorbing a reactor purge gas and an outlet line (o) for the product stream from the reactor (R). The adsorption vessel (A) is installed either upstream or downstream the sulfur guard (S) in parallel to the normal piping, thereby decreasing the risk of carbon formation in the reactor.

摘要:
An apparatus and a method for replenishing a pressure swing adsorption system with an adsorbent is disclosed in the present disclosure. The apparatus comprises a hopper arrangement and a mechanism. The hopper arrangement is disposed about an operative top of the pressure swing adsorption system. The hopper arrangement is in fluid communication with the pressure swing adsorption system via an aperture. The hopper arrangement accommodates and selectively supplies adsorbent into the pressure swing adsorption system when the amount of the adsorbent within the pressure swing adsorption system is reduced below a predetermined threshold quantity due to adsorbent escape; and/or the purity of the target fluid emanating out of the pressure swing adsorption system is reduced below a predetermined threshold purity level. The mechanism selectively controls the flow of adsorbent into the pressure swing adsorption system.

A compact coffee capsule filler appliance(10) for filling coffee capsule cups(90) with a coffee product. It comprises a housing accommodating a plurality of processing stations arranged along a processing pathway. The plurality of processing stations include a ground coffee capsule cup filling station. A capsule cup holder plate(152) is located below said pathway and adapted to hold a plurality of capsule cups(90). The capsule cup holder plate(152) is arranged to move said capsule cups(90) successively past each of said plurality of processing stations whereby each capsule cup(90) is successively filled with ground coffee. The processing pathway forms a closed loop pathway to enable a continuous process of filling capsule cups(90) in the appliance.
