APPARATUS FOR SEPARATING LIQUIDS

摘要

A separator for liq. mixts. comprising liqs. of different densities such as oil and water, comprises a settling vessel where the different liqs. separate into layers according to their density, an outlet at the top end of the inclined roof of the vessel for the lightest liq., and outlet for the next heaviest liq. and an inlet pipe for the mixt. The inlet pipe, the heaviest liq. outlet pipe and the lightest liq. outlet pipe are all constructed as open-topped standpipes so that their interior is open to atmos. In normal operating conditions, the level of the incoming liq. mixt., the level of the liq. constituent having the second lightest (in the present case the heaviest) liq. and the level of the boundary layer between these two liqs. all lie in the region of these associated standpipes.
