Abstract
A method, system, and device for separating components is described. A vessel is provided. A first volume of a process liquid, containing a first component and a second component, is passed into an inner chamber. The piston retracts to a first position. The fluid inlet is closed. The piston is retracted to a second position, causing the first component and a first portion of the second component to flash to form a vapor stream while a second portion of the second component freezes to form a solid product stream. The fluid outlet is then opened. The piston is advanced to a third position that results in a third volume, smaller than the first volume, such that the vapor stream is expelled. The fluid outlet is closed. The piston is fully closed such that the solid product stream is pressed into and extruded through the solids outlet.
