The system has the advantages of (1), sufficiently utilizing carbon dioxide in purified waste gas of coal chemical synthesis gas, greatly reducing the quantity of the carbon dioxide discharged to the atmosphere and reducing environmental pollution, (2), extensively utilizing caustic soda unsalable in markets and reducing caustic soda storage and transport costs, and (3), greatly reducing cost for producing sodium carbonate and baking soda products and increasing grade of the sodium carbonate and baking soda products.
Description
Technical field
The utility model relates to a kind of system that produces soda ash and sodium bicarbonate, particularly relate to a kind of utilize in the chlor-alkali production white liquor with reclaim carbonic acid gas in the Coal Chemical Industry purified synthesis gas waste gas and produce the system of soda ash and sodium bicarbonate.
Background technology
The method of industrial production soda ash is more, as: natural alkaline process, solvay soda process, connection alkaline process etc., urao is less at China's reserves, and the calcium chloride of solvay soda process by-product can cause environmental pollution, and the ammonium chloride fertilizer market capacity that the connection alkaline process is produced is limited, can't enlarge scale.Industrial sodium bicarbonate is mainly produced by the soda ash carbonization.
At present, domestic polyvinyl chloride project is numerous, this project mainly be by Coal Chemical Industry prepare ethene, chemical industry for making chlorine and alkali prepares chlorine, then by the two the preparation polyvinyl chloride.Wherein Coal Chemical Industry prepares in the ethylene process, and the cleaning section of synthetic gas has a large amount of high-pureness carbon dioxides (its volumetric concentration is greater than 82%) to efflux, and atmospheric layer is caused bigger influence, has increased the weight of " Greenhouse effect " of the earth; And the white liquor (its mass concentration is 30%) that produces when producing chlorine in the chlorine industry stagnates on market and sells, because white liquor has stronger corrosion and pungency, its storing cost is higher.
