Multi Column Distillation Plant Multiple Effect Stills The Neelam multiple effect stills consist of a series of pressure vessels in the form of columns, called distillation columns or effects, that are interconnected, communicating vessels. Each column is divided into two parts: a double tube sheet (DTS) heat exchanger that acts as an evaporator, and an upper chamber used to separate pyrogens preventing the drops carrying impurities from reaching the end of the column. Multi Column Distillation Plant is supplied as a compact unit on a skid with all components readily accessible.
