chlorine; the salt-sulfuric acid production process; and, as a co-product in the manufacture of silica. Most hydrochloric acid is produced from the chlorination of organic chemicals with much smaller amounts from the other processes. OxyChem produces its hydrochloric acid by combining hydrogen and chlorine in "acid burners".
The as-prepared superhydrophobic quartz sand was used as a high performance filter to separate the mixture of oil and water. The experimental device is shown in Fig. 5(a). The quartz sand was placed into a sand core funnel to form a filter medium by supporting with metal mesh (300 mesh per inch).

Filters capture particles through the mechanisms of impaction, interception and diffusion. Additionally, these filters are enhanced with electrostatically charged fibers to help trap particulates within the filter media. As particulate filters load up with the contaminant, they typically become more efficient; however, they also become harder to
