摘要:
A wearable oxygen concentrator can be used in both an ambulatory mode and a stationary mode. The wearable oxygen concentrator is physically connected to a docking station in the stationary mode such that it can draw power from the docking station and remain energy efficient in both modes. The disclosed oxygen generation system incorporates effective gas flow by means compressor configurations for use in lower flow ambulatory modes and higher flow stationary modes.

The present invention relates to a method to remove one or more contaminant from a gas stream, preferably a hydrocarbon gas steam, using a solid adsorbent, preferably a porous cross-linked polymeric adsorbent, a pyrolized macroporous polymer, or mixtures thereof and regenerating said adsorbent by an improved pressure swing adsorption process wherein a portion of the product gas is heated and used as the purge gas.

Methods are provided for synthesizing ZSM-58 crystals with an improved morphology and/or an improved size distribution. By controlling the conditions during synthesis of the ZSM-58 crystals, crystals of a useful size with a narrow size distribution can be generated. Additionally, by controlling the ratio of water content to silica content in the synthesis mixture, it has unexpectedly been found that ZSM-58 crystals can be formed with an improved morphology. The improved morphology can result in ZSM-58 crystals with a more uniform size across the various dimensions of the crystal, which allows for more uniform diffusion within the crystal. This is in contrast to conventionally synthesized crystals, where the size of the crystal can vary along different axes of the crystals.

摘要:
Provided are encased parallel channel adsorbent contactor apparatus and systems and swing adsorption processes related thereto. Encased parallel channel adsorbent contactors are useful in swing adsorption processes. A plurality of the encased adsorbent contactors are loaded and sealed together in a swing adsorption vessel such that substantially an entire feed stream must pass through the channels of the contactors and not through stray gaseous stream paths between contactors.
摘要:
A temperature swing adsorption process for the removal of a target species, such as an acid gas, from a gas mixture, such as a natural gas stream. Herein, a novel multi-step temperature swing/pressure swing adsorption is utilized to operate while maintaining very high purity levels of contaminant removal from a produc t stream. The present process is particularly effective and beneficial in removing contaminants such as C0 2 and/or H 2 S from a natural gas at relatively high adsorption pressures (e.g., at least 500 psig) to create product streams of very high purity (i.e., very low contaminant levels).
摘要:
The present application is directed to a method and system for preparing gaseous utility streams from gaseous process streams, particularly, removing oil contamination from such streams prior to use in a dry gas seal. The methods and systems may include at least one kinetic swing adsorption process including pressure swing adsorption, temperature swing adsorption, calcination, and inert purge processes to treat gaseous streams for use in dry gas seals of rotating equipment such as compressors, turbines and pumps and other utilities. The adsorbent materials used include a high surface area solid structured microporous and mesoporous materials.

A portable oxygen concentrator system weighing 4-20 pounds adapted to be readily transported by a user and for delivering oxygen to lungs of the user includes a rechargeable energy source; a concentrator powered by said energy source and adapted to convert ambient air into concentrated oxygen gas for said user; and a control unit that controls the concentrator to deliver a flow rate based on at least one of a Body Temperature Pressure Dry (BTPD) condition, a Body Temperature Pressure Saturated with water (BTPS) condition, and a condition between BTPD and BTPS, where relative humidity is 0-100%, to maintain a constant fraction of inspired oxygen (FI02) in the lungs of the user.
摘要:
Guard layers are employed in the adsorbent beds of rapid cycle pressure swing adsorption (RCPSA) devices to protect the adsorbent therein from certain contaminants (e.g. water vapour). Conventional PSA devices typically pack the guard layer with as much guard material as is practical. In RCPSA devices however, the performance of the guard layer can be improved by using a reduced amount of guard material and increasing access to it. Such embodiments are characterized by guard layers with a channel fraction of greater than 50%.
