Abstract
Disclosed herein is a method for recovering water from a salt solution. The method can include mixing the salt solution with a salting out solution that includes at least one enolizable ketone and at least one alcohol. The salting out solution can absorb the water from the salt solution and the water can be released using a regenerant solution. A base solution can also be added to fully regenerate the salting out solution so that it can be reused.
Claims30
A method for recovering water from a salt solution, comprising:
- mixing a salt solution and a salting out solution in a first container to form solid salt and a water-absorbed salting out solution, wherein the salting out solution comprises an enolizable ketone and an alcohol;
- removing the water-absorbed salting out solution from the first container;
- mixing the water-absorbed salting out solution with a regenerant solution in a second container to release absorbed water from the water-absorbed salting out solution and form an organic phase and an aqueous phase in the second container;
- removing the aqueous phase from the second container;
- desalinating the aqueous phase to produce purified water.
A method for recovering water from a salt solution, comprising:
- mixing a salt solution and a salting out solution in a first container to form solid salt and a water-absorbed salting out solution, wherein the salting out solution comprises a ketone, an alcohol, an amphiphilic oxygenate, and a demulsifier;
- removing the water-absorbed salting out solution from the first container;
- mixing the water-absorbed salting out solution with a regenerant solution in a second container to release absorbed water from the water-absorbed salting out solution and form an organic phase and an aqueous phase in the second container;
- removing the aqueous phase from the second container;
- desalinating the aqueous phase to produce purified water.
A method, comprising
- mixing a salt solution and a salting out solution to form solid salt and a water-absorbed salting out solution, wherein the salting out solution comprises an enolizable ketone and an alcohol;
- mixing the water-absorbed salting out solution with a regenerant solution to release absorbed water from the water-absorbed salting out solution and to regenerate the enolizable ketone;
- and
- regenerating the alcohol using a base solution.
