Chemical storage of wind energy by renewable methanol production: Feasibility analysis using a multi-criteria decision matrix

open access: yesEnergy, 2015
Abstract This study is for the technoeconomic analysis of an integral facility consisting of wind energy-based electrolytic hydrogen production, bioethanol-based carbon dioxide capture and compression, and direct methanol synthesis. ASPEN Plus was used to simulate the facility producing 97.01 mt (metric tons) methanol/day using 138.37 mt CO 2 /day ...

Chemical fixation of electroplating sludge and microstructural analysis of stabilised matrix using fly ash and cement

open access: closedMaterials Research Innovations, 2009
AbstractStabilisation and microstructural examination of stabilised electroplating industrial sludge has been studied. Investigations were undertaken to formulate cementitous binder by judicious blending of fly ash, sludge and cement with five mix proportions. The major metallic contaminants were cadmium, chromium, copper, nickel and lead.
