148 PROCESS FOR PREPARING ULTRA-FINE SODIUM BICARBONATE POWDER EP07719419.9 2007-03-26 EP2007681A1 2008-12-31 TINSON, Art; D'UVA, Salvatore; HU, Jianzhong; LEFAS, John
Ultra-fine sodium bicarbonate powder (mean particle size less than 5 microns) is produced by the mixing and reaction under agitation at control temperatures of solutions of ammonium bicarbonate and sodium chloride. Precipitated sodium bicarbonate is separated by filtration as a slurry which is dried to produce ultra-fine sodium bicarbonate. Ultra-fine sodium bicarbonate produced by this method also exhibits a narrow particle size distribution which is advantageous in blowing agents for thermoplastic resins, to produce a foamed resin with small cells of a narrow size distribution.

152 PROCESS FOR DESALINATION OF SEAWATER EP00975010.0 2000-09-27 EP1335881B1 2004-06-02 Rongved, Paul
The invention relates to desalination of Seawater and of brackish water and removal of harmful CO2 gas in exhaust from combustion apparatuses. The exhaust, rich in carbon dioxide (CO2) is diverted to a process chamber, where Seawater, after being mixed with ammonia, as a catalyst to weaken the salt molecules, is pumped into the chamber and dispersed at many points near the top as a fine spray, exposing the salt to the CO2 gas there. The internal bonds of the salt molecules (NACl) are weaker by the ammonia in the water attaching and pulling on their Cl atom. The CO2 in the chamber is attaching and pulling on the Na atom of the salt molecules and further reduces the bond, breaking them apart. Two heavy solids are formed and are removed in a clarifier below. Desalinated seawater in large quantities per ton of salt, over flows from the clarifier, for use in communities and for agriculture. Therewith is also harmful CO2 in the exhaust removed, before being discharged from the process chamber to the environment. The solid NH4Cl can be recycled for ammonia and the second solid NH2CO3 is a saleable product, which may more than pay for the process.

158 Verfahren zum Entfernen von Schwefeloxiden aus chloridhaltigen Verbrennungsabgasen EP79200210.7 1979-05-04 EP0005301A1 1979-11-14 Voeste, Theodor, Dipl.-Chem.

Verfahren zum Entfernen von Schwefeloxiden aus Verbrennungsabgas, insbesondere Kraftwerksabgas, wobei das Abgas durch eine Reaktionszone strömt, die nach der Art eines Sprühtrockners arbeitet. In die Reaktionszone wird eine Reinigungsflüssigkeit eingesprüht, die aus einer wässrigen Lösung von Soda und/oder Natriumbicarbonat besteht. In der Reaktionszone wird der Wassergehalt der Reinigungsflüssigkeit durch den Wärmeinhalt des Abgases praktisch vollständig verdampft und das Abgas anschliessend durch ein Filter geleitet. Aus der Reaktionszone und dem Filter werden wasserfreie Feststoffprodukte abgezogen, die zu mindestens 75 Gew.% aus Natriumsulfit, Natriumsulfat und Natriumchlorid bestehen. Diese Feststoffprodukte werden wieder zu Soda aufgearbeitet. Zu diesem Zweck werden die Feststoffprodukte gelöst, Sulfit zu Sulfat oxidiert, so dass eine Natriumsulfat und Natriumchlorid enthaltende Lösung entsteht. Aus dieser Lösung wird das Sulfat abgetrennt und die verbleibende Lösung durch das Solvay-Verfahren zu Soda aufgearbeitet.

160 Method and apparatus on halting global warming US15618031 2017-06-08 US20170275173A1 2017-09-28 Hsiao-Yuan Li
We have described herein a method and associated apparatus that can halt global warming with significant economic benefits. They include (1), re-scrub half the carbon dioxide emitted from calcining baking soda into soda ash to produce twice as much soda ash and twice as much ammonium chloride as comparing with the standard Solvay ammonia soda ash process; Use the ammonium chloride as sugarcane fertilizer producing fuel ethanol, and bagasse, a photosynthesized bio-fuel from carbon dioxide already presented in the earth atmosphere for power generation, and (2), expand the sugarcane plantation areas into desert oasis using desert heat to produce distilled water for irrigation, pumped by solar heated hydraulic press pumps to supplement insufficient rain forest resources on earth's continents to accelerate reaching “carbon neutral” on capture annually twenty five billion tons of anthropogenic carbon dioxide from earth atmosphere economically.
