Abstract
Equipment, systems, processes and techniques for conducting processing of solutions are described. The techniques can be applied to provide diluted solution (i.e. purified solvent), concentrate solution or each. A variety of specific equipment, example systems and processes are depicted and described.
Claims9
A process for processing a solution;
- the process comprising:
- with a reverse osmosis system including:
- (a) a first solvent-generating reverse osmosis unit including:
- a high pressure side inlet;
- a high pressure side outlet;
- and, a low pressure side outlet;
- and,
- (b) an intermediate reverse osmosis unit system including at least a first intermediate reverse osmosis unit having:
- a high pressure side inlet;
- a low pressure side inlet;
- a high pressure side outlet;
- and, a low pressure side outlet;
- operating the reverse osmosis system such that:
- (i) solution is directed into the high pressure side inlet of the first solvent-generating reverse osmosis unit;
- (ii) solvent is removed from the low pressure side outlet of the first solvent-generating reverse osmosis unit;
- (iii) there is no low pressure side inlet flow into the first solvent-generating reverse osmosis unit;
- (iv) outlet flow from the high pressure side outlet of the first solvent-generating reverse osmosis unit is directed into the high pressure side inlet of the first intermediate reverse osmosis unit;
- (v) the first intermediate reverse osmosis unit is operated with:
- a high pressure side inlet flow;
- a low pressure side inlet flow;
- a high pressure side outlet flow;
- and, a low pressure side outlet flow;
- (vi) flow into the high pressure side inlet of the first solvent-generating reverse osmosis unit comprises the low pressure side outlet flow from the first intermediate reverse osmosis unit;
- and
- (vii) at least a portion of the high pressure side outlet flow of the first solvent-generating reverse osmosis unit is fed to the low pressure side inlet flow of the first intermediate reverse osmosis unit.
