  • Combined solid waste, carbon dioxide quicklime sparging, brine water, and reverse osmosis/ion exchange processes for the production of soda chemicals
    Patent number: 8623316
    Abstract: The proposed invention uses a classical chemical equation where carbon dioxide CO2 is reacted with quick lime Ca(OH)2 to produce soda carb NaHCO3 and concentrating it to 6% using advanced membrane and resin technology. The invention requires three chemicals CO2, Ca(OH)2, and sodium chloride NaCl to produce NaHCO3. The output of many industrial processes lacks waste heat and in many instances CO2 and the present invention combines a solid waste processing unit to the above processes which allows the production of solid products or high % liquors. Availability of waste heat sources can lead to high efficiency in NaHCO3, Na2CO3, and NaOH production. The process is not chloro-alkali electrochemical or Solvay column ammonia processing technique. Advanced membrane uses technologies of reverse osmosis and nanofiltration systems while resin technology uses ion exchange systems. Therefore, we conveniently call it the solid waste-quicklime membrane SWQM process.
