Environmental Experiments in Chemical Engineering Laboratory

9451126 Dural该项目将通过增加实验室实验来补充化学工程课程，这将使学生接触两个主要领域：空气污染控制和工业废水净化。第一个实验将演示通过活性炭吸附从污染空气中去除挥发性有机化合物。目前用于演示氦/氮分离的固定床吸附装置将被空气污染实验所取代，并进行修改，以便能够去除多组分污染物混合物。第二个实验将演示通过反渗透对工业废水流的改造。将设计中试规模的反渗透系统，并将其用于净化含有污染物混合物的模拟含水工艺流。该系统将允许学生检查过程变量，如施加的压力，进料浓度，温度和进料流速对溶质排斥和水回收，同时他们获得了广泛使用的废物处理方法的实践经验。

9451126 Dural This project will supplement the chemical engineering curriculum by adding laboratory experiments which will expose the students to two major areas: air pollution control and industrial waste water purification. The first experiment will demonstrate removal of volatile organic compounds from contaminated air by activated carbon adsorption. A fixed bed adsorption unit currently being used to demonstrate helium/nitrogen separation will be replaced with the air pollution experiment, and modified to enable the removal of multi component pollutant mixtures. The second experiment will demonstrate renovation of industrial waste streams by reverse osmosis. A pilot scale reverse osmosis system will be designed and used to purify a simulated aqueous process stream containing a mixture of contaminants. The system will permit the students to examine the process variables such as applied pressure, feed concentration, temperature, and feed flow rate on solute rejection and water recovery while they are gaining hands-on experience with a widely used waste treatment method.
