To investigate the safety and environmental issues related to the process INTRODUCTION Textile industries utilize a huge amount of water within its processes. It also produce a massive quantities of wastewater which are classified into four categories namely; hard to treat, dispersible, hazardous or toxic wastes and high volume wastes. JORDAN has one of the most stringent environmental regulations, especially those related to discharge limits. Wastewater is usually treated using different technologies such as chemical coagulation in which Alum and other chemicals are added to water to form tiny sticky particles called "flocs" which attract the dirt particles. The combined weight of the dirt and the flocs become heavy enough to sink to the bottom during sedimentation. On the other hand, chemical coagulation needs to additional chemicals and produce large amount of sludge which needs to be disposed or have a special treatment. One of promising methods for treating textile waste effluents is electrocoagulation. Electrocoagulation utilizes Aluminum or Iron anodes to produce hydroxides flocs which can effectively remove different types of pollutants. The process can be described as follow: OUTLINES General Equation: M input + M generation – M output – M consumption =M accumulation For the continuous-steady state process : accumulation= 0. (no build-up of anything in the system , generation and consumption= 0. (no chemical reaction occurs. The general equation becomes: M input = M output OBJECTIVES

Combustion Zone: CFB Column: Fluidization Calculations: ΔPbed=100 kpa Ut=6.96 m/s r = 7.02 m H.E ( steam condenser ) : Total Income (T.I) = 365 + 50 = 415 MM Dollar Profit Indicators: From the study on oil shale in Jordan that has been discussed in this project, oil shale forms a large source of energy that has not been used yet. The process that had been selected depends on the wanted product, as we look for a source of electricity; we decided that best process to achieve this objective of our project is ATP technology. As a development country that does not have natural resources (i.e. water) as well as energy resources (i.e. crude oil), oil shale plant extraction is promising, with (T.C.I) = 3 billion dollars and 9 years Payback-Period. We conclude that producing oil shale is very effective since 1000 kg of oil shale is enough to generate 36 gal of oil (138 L of oil). Increasing the capacity of production to become more feasibility production. Environmental emissions should be controlled during processing to meet the standard international conventions that promote environmental protection and sustainable development and carefully consider the Equator Principles in structuring environmental management programs for oil shale projects.
