Life Cycle Assessment Study For Two Different Phenol Production Processes
Phenol is an important raw material in many branches of industry (petrochemical pharmaceutical plastic and pesticidal chemical industry ). This research study on phenol production processes by using two different phenol production processes which are cumene oxidation (the Hock process) and toluene oxidation (the Dow process). In order to study in environmental impacts Life Cycle Assessment (LCA) is applied to evaluate environmental impacts of phenol production processes. Environmental impacts are evaluated according to cradle-to-gate approach by using SimaPro 7.1 software for Life Cycle Assessment . Approach by IMPACT 2002+ . The result shows that cumene process is more environmentally favorable than toluene process.
Life Cycle Assessment for the Activated Carbon Production by Coconut Shells and Palm-Oil Shells
Activated carbon also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. In this research studies environmental impacts of activated carbon production processes which produced from two types of agricultural by-products namely : coconut shells and palm-oil shells . SimaPro software is applied to evaluate the environmental impacts of both processes. The results have shown that the environmental impacts for the process using coconut shells as raw material is higher than that using palm –oil shells as raw material.
Life Cycle Assessment of Brown Sugar
The sugarcane and sugar industry had been an important part of economy of Thailand. As of the year 2006 Thailand was the 3rd world๛s exporter of brown sugar. The cultivation in year 2006-2007 of sugarcane was estimated at 63.8 million tons and the production of sugar was at 6.7 million tons (Office of the Cane and Sugar Board 2006). The environment impact of the sugarcane and sugar industry was taken into the research of life cycle assessment of 1 ton brown sugar Using the method of SimaPro version 7.1 the results found the crystallization causing high environmental damage was global warming 81% ozone depletion 56% acidification and eutrophication 78%.
