Integrated membrane/adsorption process for gas separation

Natural Gas Purification Technologies - Major Advances for CO2 Separation and Future Directions

“…The integration of membranes with other separation processes such as PSA are also wellestablished in the chemical and petrochemical industries (Choe, Auvil et al 1987;Doshi 1987;Doshi, Werner et al 1989;Doshi and Dolan 1995;Feng, Pan et al 1998). Membrane permeation can be an effective aid in the pressurization and high-pressure adsorption steps of a typical PSA process; the pressure difference available from the PSA can be used for operating the membrane incorporated into the blowdown step of the PSA cycle (Esteves and Mota 2007).…”

Simulation of binary gas separation with asymmetric hollow fibre membranes and case studies of air separation

“…Significant contributions have been provided by Agrawal and Xu (1996), Agrawal (1997), Bhide and Stern (1991a,b), Ettouney et al (1998), Feng et al (1998a,b, 2000, Pan (1986) and Sengupta and Sirkar (1983, 1987 to address some of the important aspects in producing a given product purity with membranes. A number of possible module configurations have been proposed, including single permeation stage, recycle, and multi-stage cascades.…”

Comparative study between a CMS membrane and a CMS adsorbent: Part I—Morphology, adsorption equilibrium and kinetics

“…The main benefit of this technology is its simplicity and easy scale-up; it can be also easily combined with other processes such as PSA (PSA-M) [4,5]. In 1980 membrane-based processes for gas separation found industrial large scale application by Permea (USA), for hydrogen separation [6].…”
