Biogas Upgrading by Pressure Swing Adsorption

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...

Hazardous dichloromethane recovery in combined temperature and vacuum pressure swing adsorption process.

Organic vapors emitted from solvents used in chemical and pharmaceutical processes, or from hydrocarbon fuel storage stations at oil terminals, can be efficiently captured by adsorption onto activated carbon beds. To recover vapors after the adsorption step, two modes of regeneration were selected and could be possibly combined: thermal desorption by hot nitrogen flow and vacuum depressurizatio...

BK1064-ch68_R2_250706 PRESSURE SWING BATCH DISTILLATION FOR HOMOGENOUS AZEOTROPIC SEPARATION

The separation of the homogeneous azeotropic mixture acetonitrile/water by pressure swing distillation (PSD) is considered. The PSD is operated as a discontinuous (batch) process and two batch modes, regular and inverted, are considered. The processes are analysed, aspects as to which batch mode should be preferred are discussed, and a dynamic model for both batch PSD processes is formulated. T...

Separation of tetrahydrofuran and water using pressure swing distillation: Modeling and optimization

−Computer simulations were performed to obtain highly pure tetrahydrofuran (THF) with over 99.9 mole% from the mixture of THF and water. Pressure swing distillation (PSD) was used since the azeotropic point between tetrahydrofuran and water can be varied with pressure. A commercial process simulator, PRO/II with PROVISION release 8.3, was used for the simulation studies. The Wilson liquid activ...
