A vertical cylindrical settler separator is to be designed for separating a mixture flowing at Q=30m/h and a containing equal volumes of a light hydrocarbon liquid (pb=875 kg/m) and a dilute solution of wash water (PA= 1000 kg/m). Ideal laboratory experiments indicate a settling time of 20min is needed to adequately separate the two phases. Assume that the tank is a cylindrical vessel with a diameter equals 1.5times its height, and that 1/4" of the vessel volume is vapor space vented to the atmosphere. Use the notation given in accompanying Figure. feed licht Dates liquid (a) For design purposes use a 30min settling time and calculate the 2-phase liquid volume ! (b) What is the vessel volume and the dimensions (D and H)! (c) What is the height of the vapor hvap in this case ? (d) Based on hydrostatic principle give the relationship between the liquid levels of the light and heavy liquids he, hal, and the adjustable height hA2 of the heavy liquid overflow. (e) At what level haz the decanter is operated if the light liquid Liquid height is to be maintained at 30% of H ? (f) In case the light liquid stream reveals the presence of significant amounts of heavy phase what conclusion would you draw ? (Bonus !) heavy liquid overflow F2.36 Chuperiyarrible
