Over the past several years field trials have been conducted by MTR of membrane-based CO 2 capture technology at the National Carbon Capture Center (NCCC) in Wilsonville, Alabama. Prior results from 2012 to 2014 have demonstrated successful operation

Composite membranes typically consist of a nonporous layer on top of a porous support. The porous support restricts diffusion in the top layer because molecules can exit the layer only where a pore is present and this reduces the permeance of the mem

A membrane-based pilot plant for carbon dioxide capture from the flue gas of a coal-fired power plant has been installed and operated at the National Carbon Capture Center in Wilsonville, Alabama, USA. The membrane system is sized to treat flue gas c

This paper describes ideas together with preliminary experimental results for applying solvent nanofiltration to liquid phase organic synthesis reactions. Membranes for organic solvent nanofiltration have only recently (during the 1990s) become avail

The separation of reaction products from catalysts is a major problem existing in many forms of homogeneous catalysis, including phase transfer catalysis and transition metal catalysed reactions. This study describes a new and generic approach to sol

A series of solvent resistant polyimide membranes, with nominal molecular weight cut-offs (MWCO) between 230–700 Da, are evaluated through high pressure filtration of six solutes dissolved in toluene. These solutes range in MW from 142 to 311 Da, a

This paper explores the use of nanofiltration (NF) membranes in phase transfer catalysis for separating the catalyst and product present in the post-reaction mixture and recycling the catalyst. The conversion of bromoheptane into iodoheptane with tol

The recycle of homogeneous Heck catalysts from post-reaction mixtures using solvent resistant nanofiltration (SRNF) membranes is known to increase catalytic productivity. However, the technique is sensitive to catalyst stability when applied to conve

Substantial increase in homogeneous catalyst productivity for a well known Heck coupling was achieved by nanofiltration-coupled catalysis. The use of nanofiltration membranes enabled catalyst separation and allowed subsequent catalyst recycle and reu
