MY149722A - Method of removing and solidifying carbon dioxide from a fluid stream and fluid separation assembly - Google Patents

Abstract

THE INVENTION RELATES TO A METHOD OF REMOVING CARBON DIOXIDE FROM A FLUID STREAM BY A FLUID SEPARATION ASSEMBLY. THE FLUID SEPARATION ASSEMBLY HAS A CYCLONIC FLUID SEPARATOR (1) WITH A TUBULAR THROAT PORTION (4) ARRANGED BETWEEN A CONVERGING FLUID INLET SECTION (3) AND A DIVERGING FLUID OUTLET SECTION (5) AND A SWIRL CREATING DEVICE (2). THE SEPARATION VESSEL (21) HAS A TUBULAR SECTION POSITIONED ON AND IN CONNECTION WITH A COLLECTING TANK (23). IN THE METHOD, A FLUID STREAM WITH CARBON DIOXIDE IS PROVIDED. SUBSEQUENTLY, A SWIRLING MOTION IS IMPARTED TO THE FLUID STREAM SO AS TO INDUCE OUTWARD MOVEMENT. THE SWIRLING FLUID STREAM IS THEN EXPANDED SUCH THAT COMPONENTS OF CARBON DIOXIDE IN A META-STABLE STATE WITHIN THE FLUID STREAM ARE FORMED. SUBSEQUENTLY, THE OUTWARD FLUID STREAM WITH THE COMPONENTS OF CARBON DIOXIDE IS EXTRACTED FROM THE CYCLONIC FLUID SEPARATOR (1) AND PROVIDED AS A MIXTURE TO THE SEPARATION VESSEL (21). THE MIXTURE IS THEN GUIDED THROUGH THE TUBULAR SECTION TOWARDS THE COLLECTING TANK (23) WHILE PROVIDING PROCESSING CONDITIONS SUCH THAT SOLID CARBON DIOXIDE IS FORMED. FINALLY, SOLIDIFIED CARBON DIOXIDE IS EXTRACTED.
