Nanofiltration Membranes Assessment for Organic Systems Separations

In this book a unique protocol for selecting, evaluating, characterizing, and modifying potential Solvent Resistant Polymeric Nanofiltration (SRNF) membranes for organic solvent separation as well as elucidating some of the underlying principles are presented. Organic solvent separation systems are encountered in industries including the petroleum, petrochemicals, pharmaceutical, biotechnology and fine chemicals where polymeric membranes and if not selected or modified properly may result in very low performances as results of possible excessive swelling and compaction. Ultrasonic Time Domain Reflectometry (UTDR) is involved for in-situ and real-time chemical (swelling) and mechanical (compaction) analysis as well as characterization while the membrane is permeated with an organic solvent or feed of interest. Performance parameters used to assess the membrane include flux, rejection, separation factor, solute and solvent relative recoveries and relative solute loss. These performance parameters provide an approach to access and monitor the effects of operating conditions on both solute purification and solvent recovery for re-use.

Epoxy Clay Nanocomposites

Development of Epoxy Clay Nanocomposites with fine dispersion and exfoliated morphologies is a challenge, since high shear is always required but epoxy has low viscosity (in general). Direct stirring of organoclay and epoxy with mechanical stirring and sonication is widely used to disperse nanoclay in epoxy. However it is not enough for good dispersion of clay in epoxy. The solvent assistance method can help to improve the dispersion of clay in epoxy. However, a lot of solvent was used and significant time was required for removing the solvent. This research monograph deals with nanocomposite materials of organic epoxy layered silicate. A solvent-free stirring method is used to fabricate the epoxy nanocomposites. The effect of chemistry of clay intercalants, chemistry of hardener and epoxy formulations on processing, curing kinetics, morphology and properties of epoxy nanocomposites is discussed.

The Vapor Extraction (VAPEX) Process in Fractured Heavy Oil Systems

The Vapor Extraction (VAPEX) has been studied theoretically and experimentally. In the first part of this work, the VAPEX process was simulated using a compositional simulator on conventional and fractured systems. Different patterns of solvent flow in fractured model comparing to the conventional model, solvent spread through fractures matrix, formation of solvent chamber, and oil recovery factor under different solvent injection schemes, effects of diffusion and fracture spacing on the process were studied and discussed. A significant finding for the application of the VAPEX process in fractured reservoirs was that fractures of poor connectivity improve the effectiveness of VAPEX process. In the second part of this work, the VAPEX process was studied experimentally using a rectangular physical model. Propane ( pure and mixed with methane) was used as solvent in all experiments. It was found that heavy oil recovery is improved as the approach pressure, defined as the saturation pressure minus operating pressure, decreases regardless of solvent composition or operating pressure. These results provide a better insight into field scale implementation of the VAPEX process.
