Abstract:
A method for removing a relatively heavy liquid from a container having a plurality of liquids of differing specific gravities, the method including the steps, not necessarily in the order presented, of:(a) providing a sealable access to the container;(b) placing a conduit within the container such that an opening adjacent to a first end of said conduit is located within the relatively heavy liquid to be removed;(c) operably connecting a second portion of said conduit at a distance from said first end to said sealable access;(d) sealing the container such that a pressure can be generated between a portion of the container and a surface of a relatively light liquid located within the container; and(e) introducing a superatmospheric medium into the container from an exterior source to generate said pressure such that said relatively light liquid acts as a plunger to transfer said pressure to said relatively heavy liquid and force at least a portion of said heavy liquid through said conduit to a location exterior of the container via said sealable access.
