ABSTRACT:
The present invention is for a method of regenerating diluted brine containing hardness from a water softening process. The process includes the steps of contacting the diluted brine with a weak acid ion exchange resin to remove the hardness from the brine and evaporating part of the water from the brine using heat from a production casing gas. The production casing gas comes from a producing oil well of a steam injection secondary oil recovery process. The regenerated brine can then be used to regenerate further quantities of strong acid resin which are used to soften water. The softened water can be used for making steam for use in a steam injection secondary oil recovery process.
