Pneumatic Capsule Pipeline, Purdue Ect Team Jan 2007

Pneumatic Capsule Pipeline, Purdue Ect Team

ECT Fact Sheets Archive

Pneumatic capsule pipeline (PCP) uses wheeled capsules (vehicles) to carry cargoes through a pipeline filled with air. Modern large diameter PCP systems utilize through flow booster pumps, also known as jet pump injectors. These create the pressure differentials required to propel multiple capsules through a pipeline, while allowing both terminals at atmospheric pressure. This is done by placing a booster pump midway along the pipeline, and designing it in such a way that capsules can bypass the pump.

Dma™: Digestion Material For Asbestos, Purdue Ect Team Jan 2007

Dma™: Digestion Material For Asbestos, Purdue Ect Team

ECT Fact Sheets Archive

Current techniques for removing asbestos- containing fireproofing require the construction of air-tight barriers, labor- intensive scraping of the fireproofing, and the installation of new asbestos-free fireproofing. The DMATM product is the result of a joint development by W.R. Grace & Co. and Department of Energy's Brookhaven National Laboratory. The new technology uses a foamy solution sprayed directly onto asbestos-containing fireproofing. After absorbing into the fireproofing, the foam chemically digests asbestos fibers and dissolves them into harmless minerals. The process is the first to chemically destroy asbestos without first removing the fireproofing.
