Reactive Separation for Biodiesel Purification Using Hybrid Membrane Systems
Abstract: Biodiesel produced through transesterification typically contains several impurities, including residual glycerol, unreacted methanol, soaps, water and homogeneous catalysts, all of which reduce fuel quality and hinder compliance with EN 14214 and ASTM D6751 standards. Conventional purification techniques such as water washing, centrifugation and vacuum distillation are energy-intensive, generate large volumes of wastewater and often fail to efficiently remove polar contaminants. To overcome these limitations, this study examines a reactive separation …

Separation of p-xylene from xylene isomer mixtures within a single stage porous batch cooling crystallizer
Abstract: Crystallization based separation of p-xylene from its isomer mixtures were mostly accomplished in stirring crystallizers, suspension crystallizer and scrapping crystallizer followed by centrifugation. In this work, separation process for p-xylene, where both crystallization and separation of p-xylene in a single batch crystallizer, was performed. Upon cooling, p-xylene, which has the higher melting point than other xylene isomers (o-xylene and m-xylene), crystallizes first. Xylene mixture samples were crystallized at a lower …
