| titleOfInvention | Method and system for producing sodium carbonate, sodium bicarbonate and sodium chloride by evaporating natural alkali liquor |
| abstract | The invention relates to the technical field of clean production, and provides a method and a system for producing sodium carbonate, sodium bicarbonate and sodium chloride by evaporating natural alkali liquor. The method provided by the invention adopts a steam mechanical recompression technology to replace a multi-effect evaporation technology in the traditional method, designs a recycling process of waste gas and waste water, and can fully recover CO discharged in the process 2 The method is used for separating the saline and alkali, byproducts of sodium bicarbonate and sodium chloride products are produced, and the problem of discharge of a large amount of high-salt water is solved. The method provided by the invention is reliable and reasonable in design, can realize full component recycling in the production of the trona at low cost, realizes multiple effects of energy conservation, emission reduction, synergy and clean production, has demonstration significance for the alkali nitrate industry, and has obvious economic and environmental benefits; the invention has the advantages of low system operation cost, low energy consumption, small equipment investment and easy industrialization. |
