1. Process route

    Synthesize soda ash using carbon sequestration agents and flue gas as the main raw materials. In the neutralization tower, the carbon fixing agent reacts with carbon dioxide to generate soda ash. After the reaction is completed, the soda ash product is obtained through four effect evaporation, centrifugation, and drying.

2. Process flow

Carbon fixing agent+flue gas → carbon neutralization → evaporation → centrifugal drying → packaging → soda ash

3. Technical advantages

The scale conforms to industrial policies, the selected process technology scheme is practical and feasible, the equipment technology is mature, the product scheme is reasonable, the market prospects are broad, and it has strong market competitiveness. And the production wastewater, domestic wastewater, and cleaning wastewater of this project can all be discharged up to standard without causing significant impact on the surrounding environment.

4. Downstream direction

(1) The glass industry is the largest consumer of soda ash, consuming 0.2 tons of soda ash per ton of glass. Mainly used for float glass, picture tube glass shells, optical glass, etc.

(2) Used in chemical engineering, metallurgy, etc. The use of heavy soda ash can reduce the flying of alkali dust, reduce raw material consumption, improve working conditions, and also improve product quality. At the same time, it can reduce the erosion effect of alkali powder on refractory materials and extend the service life of kilns.

(3) As a buffering agent, neutralizing agent, and dough improver, it can be used in pastries and noodle products, and used in moderation according to production needs.

(4) As a detergent used for wool rinsing, bath salt, medicine, and as an alkaline agent in tanning.

(5) It is used in food industry as neutralizer and leavening agent, such as manufacturing amino acid, soy sauce and flour food such as Mantou and bread. It can also be mixed with alkaline water to add to pasta, increasing elasticity and extensibility.

(6) Sodium carbonate can also be used to produce monosodium glutamate and specialized reagents for color televisions.

(7) Used in the pharmaceutical industry as an antacid and a penetrating laxative.

(8) Used for chemical and electrochemical oil removal, etching of copper and aluminum, electrolytic polishing of aluminum and alloys, chemical oxidation of aluminum, sealing after phosphating, rust prevention between processes, electrolytic removal of chromium coatings and oxide films, etc. It is also used in pre plating copper, steel plating, and steel alloy plating electrolytes.

(9) The metallurgical industry is used as a smelting flux, a flotation agent for ore dressing, and a desulfurizer for steelmaking and antimony smelting.

(10) Used as a softening agent in the printing and dyeing industry.

(11) The leather industry is used for degreasing raw leather, neutralizing chrome tanned leather, and improving the alkalinity of chrome tanning liquids.

(12) Quantitative analysis is used as a benchmark for determining acidic solutions. Measure aluminum, sulfur, copper, lead, and zinc. Test urine and whole blood glucose. Analyze the co solvents of silica in cement. Metal metallographic analysis, etc.
