BRINE CONCENTRATION

Underground salt formations are well suited to natural gas and natural gas liquids storage because the salt caverns, once formed, allow little injected natural gas to escape unless specifically extracted. The walls of a salt cavern also have the structural strength of steel, which makes them very resilient against reservoir degradation over the life of the storage facility.

Saturated brine is injected into the cavern to drive the stored gas or liquid to the surface. The excess brine is kept in storage pits on the surface. In regions where the rainfall is greater than evaporation, the brine often becomes diluted, causing damage to the salt formation when injected. A concentration process is required to return the brine to saturation.

Aqua-Pure, Fountain Quail’s parent company, operates an MVR evaporator at a Liquid Petroleum Gas (LPG) storage cavern facility in Sarnia, Ontario, Canada, that concentrates diluted salt brine to saturation. The evaporator produces saturated brine for cavern injection along with pure distilled water for use as process water at an adjacent facility.
