Abstract
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.
Claims23
A fractionation process for producing at least two concentration fractions of a fluid comprising a solute, suspended or dissolved content using at least two fluidly connected evaporator units, the process comprising the steps of:
- feeding a feed fluid comprising 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;
- evaporating a second amount of fluid from the first concentrated fluid in at least the second evaporator unit to produce a second concentrated fluid, and controlling the concentration of the suspended or dissolved content of one or more of the first, second or a further concentrated fluid within a predetermined concentration range.
A fractionation system for producing at least two concentration fractions of a fluid comprising a solute, suspended or dissolved content, the system comprising:
- a first evaporator unit for evaporating a first amount of fluid from a first feed fluid to produce a first concentrated fluid;
- and
- a second evaporator unit for evaporating a second amount of fluid from a second feed fluid to produce a second concentrated fluid;
- wherein the second evaporator unit is fluidly connected to the first evaporator unit such that the first concentrated fluid is the second feed fluid;
- and
- a controller for controlling the concentration of the suspended or dissolved content of one or more of the first, second or a further concentrated fluid within a predetermined concentration range.
