I. Overview

With the requirements of environmental protection, comprehensive and efficient use of high-purity CO2 has become a goal of everyone's attention. Our company adopts high-efficiency and low-energy consumption food-grade liquid CO2 production technology, which provides the possibility for the reuse of CO2.

Limekiln gas, flue gas, fermentation gas and other gas sources rich in carbon dioxide usually have lower pressures. Using Dakot’s low partial pressure swing adsorption (PSA) carbon dioxide recovery technology, carbon dioxide can be concentrated and further purified/liquefied. Industrial-grade or food-grade carbon dioxide products.

Our company also provides technology, engineering and equipment for enriching carbon dioxide by liquid phase method (MDEA/MEA, etc.).

2. Technical indicators:

Device scale: 1000-1000000Nm3/h

CO2 purity: ≥98% (can reach Coca-Cola standard)

CO2 pressure: 0.03-1.0MpaG

Continuous running time: ≥8000h

3. Technical features:

The PSA process is simple, the operating pressure is low: 0.03-1.0MpaG, and the product purity can reach 80-99.9%.

The device is fully automatic operation, with self-diagnosis, worry-free cutting tower and online maintenance functions.

The device runs stably, and the continuous running time is more than 8000h.

Adopt special adsorbent, advanced index;

The process is short, the process is simple, and fully automatic control can be realized.

The use of special adsorbents realizes the recovery of CO2 with high efficiency, high purity and low energy consumption, and reduces production costs.

Large operating load, effectively coping with fluctuations in raw materials.
