I. Technical Principle 

Varieties of source gases rich in CO₂ are pressed and purified after pressure swing adsorption and concentration to obtain food grade liquid dioxide after condensation, flashing and purification process. The high-purity food-grade carbon dioxide up to standards is filled into tank and bottle.

II. Technical Indicators 

Device scale: 1000~300000t/a

Purity: 98%~99.95% (v/v)

Pressure: ≥2.5MPa (G)

CO₂ yield:

III. Characteristics and Advantages 

1. A wide range of raw materials;

2. The device covers a small footprint, with high security and reliability;

3. Low energy consumption, low costs of CO₂;

4. High degree of automation, unmanned operation, without starting and stopping losses;

5. High utilization of raw materials, without environmental pollution.

IV. Application Fields 

Fermentation gas, shift gas, decarbonization regeneration gas, natural mine gas, and other gas sources containing CO₂.
