Separation and purification are an integral part and a major cost factor in the chemical industry. Distillation is a very commonly used for solvent separation and purification process. It is neither cost effective nor process efficient when dealing with close-boiling and azeotropic solvent mixtures without modifying the relative volatility of the solvent components with an extraneous solvent or...

This study presents the analysis of exergy load distribution in a separation process by extractive distillation for ethanol dehydration. The methodology carried out is divided into three parts: calculation flow considering physical and chemical exergies process; primary transformed contributions consumed exergy; finally, overall efficiency, which shows real percentage energy being used process....

The dehydration of isopropanol (IPA) is a crucial process in numerous industries, and the optimization its efficiency economic viability essential. This review provides comprehensive analysis comparison various distillation processes, heat integration (HI) strategies, intensification (PI) techniques employed for IPA dehydration. advantages, limitations, applicability such as extractive distilla...

Given the extent of tropical forest deforestation and as a number of conservation programmes and local communities rely on forest fragments, it has become important to understand how fragment exploitation by local communities affects forest structure and function. The effects of forest exploitation on forest structure and status of forest fragments were investigated in 20 nonreserved forest fra...
