Method for producing an alkali metal carbonate
Abstract
Abstract IN ONE EMBODIMENT OF THE INVENTION, AN ALKALI METAL CARBONATE IS OBTAINED BY REACTING A GAS CONTAINING CARBON DIOXIDE, SUCH AS FLUE GAS, WITH AN AQUEOUS SOLUTION CONTAINING AN ALKALI METAL HYDROXIDE, SUCH AS SODIUM HYDROXIDE. THE CARBONATE APPARATUS COMPRISES BASICALLY A HORIZONTALLY-POSITIONED ENCLOSED ELONGATED CONDUIT WHICH CONTAINS A PACKING MATERIAL. THE FLUE GAS IS DIRECTED INTO THE CARBONATOR UNIT AND MOVED HORIZONTALLY THROUGH THE PACKING MATERIAL, SIMULTANEOUSLY, THE AQUEOUS ALKALI SOLUTION IS ALSO MOVED HORIZONTALLY THROUGH THE CARBONATOR UNIT AND A PORTION OF THE LIQUID STREAM IS CONTINUOUSLY RECIRCULATED VERTICALLY DOWNWARDLY THROUGH THE PACKING MATERIAL. THE REACTION OF THE FLUE GAS WITH THE AQUEOUS ALKALI SOLUTION PRODUCES AN ALKALI METAL CARBONATE SOLUTION, A PORTION OF WHICH IS CONTINUOUSLY WITHDRAWN AT ONE END OF THE CARBONATOR UNIT FOR RECOVERY OF THE SOLID PRODUCT.
