FLUID FRACTIONATION PROCESS AND APPARATUS

摘要

The present invention relates to a fractionation process for producing at least two concentration fractions of a fluid including a solute, suspended or dissolved content using at least two fluidly connected evaporator units. The process includes the steps of: feeding a feed fluid including a solute, suspended or dissolved content into at least a first evaporator unit; evaporating a first amount of fluid from the feed fluid in at least the first evaporator unit to produce a first concentrated fluid; feeding at least a portion of the first concentrated fluid into at least a second evaporator unit; and evaporating a second amount of fluid from the first concentrated fluid in at least the second evaporator unit to produce a second concentrated fluid.
