Evaluation of Emission Pattern of Compression Ignition Engines Fuelled With Blends of Orange Peel Oil Based Biodiesel Using Artificial Neural Network Model

  Abstract It is well established that Orange peeled oil biodiesel (OPOB) is a suitable fuel in Compression Ignition (CI) engines because of its compatible physicochemical properties with diesel. Literature is however sparse on its emission characteristics in CI engines majorly because few investigations have been done due to seemingly difficult and time-consuming experiments. On this strength, this work first carried out experimental investigations on carbon monoxide (CO), unburned hydrocarbon (UHC), oxides of nitrogen (NOX) and smoke of orange peel oil based biodiesel in single cylinder, four stroke CI engine; and afterwards applied the power of artificial neural networks (ANNs) prediction model to predict to the full-scale CO, UHC, NOX, and SMOKE values of the CI engine. Brake load, orange oil-diesel mixture percentages and engine speed were the inputs of the ANN while Levenberg Marquardt (trainlm) and scaled conjugate gradient (trainscg) were the training algor...

  Juniper Publishers-Open Access Journal of Environmental Sciences & Natural Resources Microbial and Enzymatic Treatment for Decolorization of Distillery Spent-Wash (DSW) Authored by Shivam Kapoor Mini Review Being rich in sugarcane yield, all the ethanol, in India, is produced by the way of fermentation of molasses and its subsequent distillation. Sugarcane juice containing sucrose is used by the sugar industry for making sugar. The residue from the sugar-making process, referred as molasses, contains high concentrations of sucrose. Molasses is used as the substrate in fermentors for producing alcohol. The liquor after fermentation contains 8-10 percent ethanol, which is further concentrated and purified in a series of distillation columns. The dark brown opaque liquid remaining after removal of alcohol is disposable and called by various names such as spent-wash, slops, stillage, still bottom, mosto, vinasse and dunder. The distillery spent wash is characterized as one of th...
