Biogas Upgrading by Pressure Swing Adsorption

Producing Nitrogen via Pressure Swing Adsorption

Nitrogen gas is a staple of the chemical industry. Because it is an inert gas, nitrogen is suitable for a wide range of applications covering various aspects of chemical manufacturing, processing, handling, and shipping. Due to its low reactivity, nitrogen is an excellent blanketing and purging gas that can be used to protect valuable products from harmful contaminants. It also enables the safe...

Process intensification in duplex pressure swing adsorption

As an alternative to the pressure swing adsorption (PSA) based on the Skarstrom cycle or its variants, a novel two-bed PSA--called duplex PSA--has been proposed by Hirose and independently by Leavitt to get both products of high purities. Simulation and experimental studies on duplex PSA for CO2 capture indicate that CO2 can be enriched to 95 mol% of feed containing 20 mol% CO2 and 80 mol% N2. ...

Pressure Swing Adsorption Based Air Filtration/Purification Systems for NBC Collective Protection

The respiratory protection against chemical warfare agents (CWA) has become a worldwide security concern in light of the many recent international threats utilising CWA. Till date the carbon filtration was adequate to protect the soldiers from the threats of CWA. With the advent of further advancements in the CWA a new threat is looming large that is known as the carbon breakers. pressure swing...

Simulation of Pressure Swing Adsorption Process of Butane/Air Separation in Carbon-Coated Ceramic Monolithic Adsorber

The new shaped structured adsorber, carbon monolithic adsorber, are characterized by straight parallel channels separated by thin wall, high void fraction and large geometric surface area, resulting in a low pressure drop under high flow rate and large contact area. These properties make it have the advantage on adsorption application. This study simulates the adsorption separation of 30% butan...
