Specialized system designed to produce carbon dioxide (CO₂) through chemical reaction between acid and base. Utilizes reaction between citric acid (C₆H₈O₇) and sodium bicarbonate (NaHCO₃), resulting in generation of CO₂ gas, water, and salt. The produced CO₂ is then purified and compressed for various industrial applications. Particularly useful in remote or industrially underdeveloped areas.

Technical Features

• High CO₂ Recovery Rate: Achieves CO₂ recovery rate up to 90%, effectively utilizing CO₂ generated from chemical reaction

• Multi-Stage Purification: Employs equipment such as refrigeration dryers, adsorption towers, and drying towers to ensure CO₂ purity reaches 99.97%-99.99%

• Liquid Storage: CO₂ is condensed into liquid form at -18°C for easy long-term storage and on-demand gas supply

• Stable Gas Supply: Provides consistent CO₂ output pressure (0.5-0.7 MPa) to meet needs of various industries

Industrial Applications

• Beverage Manufacturing: Widely used in production of soft drinks and sparkling wines, ensuring CO₂ meets food-grade standards

• Laboratory and Industrial Gas: Supplies high-purity CO₂ for laboratories and factories, fulfilling gas needs of industrial production

• Gas Supply in Remote Areas: Offers stable and reliable CO₂ production method in regions with weak industrial infrastructure

Chemical Reaction Process

Main Reaction: C₆H₈O₇ + 3NaHCO₃ → 3CO₂ + 3H₂O + Na₃C₆H₅O₇
