Abstract
The use of Carbon Adsorption Technology for the development of a Prototype Portable Carbon Adsorption Unit was investigated. Carbon adsorption is a well-established treatment process. It is much safer and more economical in comparison with other conventional neutralisation techniques used for toxic chemical spill clean up. This thesis begins by examining the nature of toxic chemical spills, the effects on the environment and the economy, and the currently available response methods and treatment technologies. The discussion then continues into the use of Carbon Adsorption Technology for the treatment of toxic chemical spills. This is further developed by the conceptual design of a portable adsorption unit. Small scale column experiments were carried out in order to determine the flow configuration to be adopted by the unit. These experiments showed that an upflow configuration had greater potential to increase adsorption efficiency. From the conceptual design stage a full detailed design of the unit was done from which the unit was constructed. The constructed prototype portable adsorption unit was then evaluated by performing a series of adsorption experiments on a single column. The conclusion reached is that Carbon Adsorption Technology can be successfully applied on a small scale for the treatment of toxic chemical spills.
