Plastics wastes from a municipal solid waste plant have a high energy content which make it an interesting option for co-processing with coal. The potential for adding plastic waste to a coal fired Texaco IGCC (Integrated Gasification Combined Cycle) power station is examined. The resulting efficiency increases due to the improved gasification qualities of(More)
The suitability of passive capillary samplers (PCAPS) for collection of representative colloid samples under partially saturated conditions was evaluated by investigating the transport of negatively and positively charged colloids in fiberglass wicks. A synthetic pore water solution was used to suspend silica microspheres (330 nm in diameter) and(More)
