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.
Claims19
A process for processing a solution;
- the process comprising:
- with a reverse osmosis system including:
- (a) a first solvent outlet-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 outlet-generating unit;
- (iv) outlet flow from the high pressure side outlet of the first solvent-generating osmosis unit is directed into the high pressure side inlet of the first intermediate reverse osmosis unit;
- (v) flow into the high pressure side inlet of the first solvent outlet-generating reverse osmosis unit comprises low pressure side outlet flow from the first intermediate reverse osmosis unit and solution that does not comprise low pressure side outlet flow from the first intermediate reverse osmosis unit;
- and
- (vi) 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.

- (ix) solution directed into the high pressure side inlet of the first solvent outlet-generating reverse osmosis unit partially includes solution that does comprise outlet flow directly from the a low pressure side outlet of the intermediate reverse osmosis unit system;
- (x) at least a portion of high pressure side outlet flow from the first intermediate reverse osmosis unit is directed into the high pressure side inlet of the second intermediate reverse osmosis unit;
- (xi) at least a portion of low pressure side outlet flow from the second intermediate reverse osmosis unit is directed into the low pressure side inlet of the first intermediate reverse osmosis unit;
- and,
- (xii) the operation is such that the solution received from the high pressure side outlet of a selected reverse osmosis unit in the intermediate reverse osmosis unit system is split into:
- (A) a first stream which is directed into a low pressure side inlet of a reverse osmosis unit;
- and,
- (B) a second stream directed into an inlet of a reverse osmosis unit.
