Acid–Base Neutralization CO2 Production System

Product Overview

The acid–base neutralization CO₂ production system generates carbon dioxide through the reaction of citric acid and sodium bicarbonate. Combined with multi-stage purification and liquefaction processes, the system converts the gas into high-purity liquid CO₂.

With a compact structure, it is especially suitable for remote areas or regions with limited industrial infrastructure. The system provides a stable supply of high-quality CO₂, widely used in carbonated beverages and various industrial applications.

Working Principle

The system produces CO₂ through the neutralization reaction between citric acid and sodium bicarbonate, generating CO₂, citrate, and water.

The produced CO₂ gas is first pretreated and then enters a purification system, where moisture and impurities are removed step by step using a refrigerated dryer, adsorption towers, and drying units to improve gas purity.

After purification, the CO₂ is compressed and liquefied through a low-temperature condensation process, forming liquid CO₂ at approximately -18°C for storage, ensuring stable supply and efficient utilization.

Key Features

• High Recovery Efficiency: CO₂ recovery rate up to 90%, ensuring high resource utilization.
• High Purity Output: Multi-stage purification achieves CO₂ purity of 99.97%–99.99%.
• Liquid Storage Advantage: Liquefied at around -18°C for convenient transport and long-term storage.
• Stable Gas Supply: Output pressure maintained at 0.5–0.7 MPa, suitable for continuous use.
• Strong Adaptability: Performs reliably under various environmental conditions, especially in areas with limited infrastructure.

Applications

• Beverage Production: Supplies food-grade CO₂ for carbonated drinks such as soft drinks and sparkling beverages.
• Laboratory & Industrial Gas: Provides high-purity CO₂ for laboratory use and industrial processes.
• Remote Gas Supply: Enables on-site CO₂ generation in remote or underdeveloped areas, ensuring a stable gas supply.
