PROCESS FOR THE EXTRACTION OF AN ORGANIC LIQUID COMPRISING AN ORGANIC NITROGEN BASE, OUTSIDE AN AQUEOUS MOUTH OF PARTICLES OF MINERAL MATERIAL AND PROCESS FOR THE PRODUCTION OF ALKALI METAL BICARBONATE

摘要

Extraction of an organic liquid containing a water-insoluble nitrogenous organic base from an aqueous slurry of particles of inorganic material (20), according to which an inert gas (23) is circulated through the slurry. The process applies to the extraction of an amine present in an aqueous calcium chloride solution containing particles of inorganic material. IMAGE
