Abstract: There is provided a process for reducing the free fatty acid content of natural oils by contacting the crude natural oil with a solvent to produce an oil product phase substantially depleted in free fatty acids and a free fatty acid rich solvent phase containing the extracted free fatty acids and some of the glycerides, and processing the free fatty acid rich solvent phase with a membrane to recover the glycerides from the solvent phase, comprising the steps of: (a) contacting the crude natural oil with an immiscible solvent; (b) separating the deacidifed natural oil phase from the solvent phase; (c) providing a selectively permeable membrane having a first surface and a second surface; (d) transferring a portion of the solvent and a portion of the free fatty acids and a lesser portion of the glycerides from the first surface to the second surface across the membrane by contacting the free fatty acid rich solvent phase with the first surface, wherein the pressure at the first surface is greater than the press

Abstract: For distributing a sequence of symbols, an emitter station transmits to a receiver station quantum systems through a quantum channel. Each of the quantum systems belongs to a set of at least two non-orthogonal quantum states and comprises a group of at least two weak coherent states of an electromagnetic field. Each weak coherent state is in a time bin of duration t. Centers of neighboring weak coherent states in a group are separated by a time T1, with T1 greater than t. Centers of neighboring weak coherent states in adjacent quantum systems are separated by a time T2, with T2 greater than t. In addition, any two weak coherent states separated by T1+T2 are phase coherent. The receiver station comprises an optical subsystem configured to check, for received quantum systems, phase coherence of two weak coherent states of time bins separated by T1+T2.

Abstract: The present invention relates to a method for curing adhesives used in the manufacture of membrane modules containing polymeric membranes, particularly polyimide based membranes used for the nanofiltration or ultrafiltration of solutes dissolved in organic solvents using microwaves. To maximise the chemical resistance of the adhesive used in these organic solvent applications, it must be as fully reacted and crosslinked (“cured”) as possible. Typically, thermal processing (heating) of the entire membrane module is used to cure the adhesives. However, the time and temperature required to achieve this high degree of completion of reaction may damage the separation performance of the membrane contained within the membrane module. In one particular aspect, this process utilises microwaves to preferentially promote the curing of epoxy adhesives over the general heating of the membrane module.
