Performance characteristics

Our degassing tower is designed with high-performance packing to provide optimal mass transfer, and ensuring precise degassing results with low carbon dioxide gas consumption.

The deoxidation unit incorporates a flow detection balance system, a mass transfer tower, a flow distributor within the tower, and high-efficiency packing. The entire deoxygenation system pipelines and valves are integrated on one platform. All process pipelines are welded using argon arc welding to guarantee optimal hygiene. In addition, the tower interior is polished to eliminate potential sanitation dead corners.

Configuration features:

• Front balance unit: Maintaining a stable water supply flow rate ensures that the water film and carbon dioxide gas flow form convection when passing through the mass transfer tower to achieve a stable mass transfer effect. To achieve a stable deoxygenation effect, the relative constant flow rate of both is one of the necessary conditions.
• Deoxygenation unit: The good flow distribution effect combined with the efficient packed tower design enables the water entering the tower to be instantly distributed on the packing, forming a large surface area, thereby effectively transferring carbon dioxide and producing high-quality deoxygenated water.
• Level control unit: According to specific liquid level requirements at different stages of the system operation, the controller automatically detects and regulates the level in accordance with the established procedures. The system mainly consists of a liquid level detection system, a frequency conversion control system and corresponding control programs.
• Cooling unit: It is mainly composed of plate heat exchanger, constant temperature control of refrigerant, and a temperature control system for degassing water.
• CO2 replacement unit: The system consists of a pressure stabilizing device, flow meters, and pneumatic valves, and is controlled by a PLC controller. The evacuation and replacement process is is performed according to a predefined protocol, thereby minimizing both deoxidation time and oxygen content.
• CO2 addition and mixing unit: The system consists of a pressure stabilizing device, flow meters, and pneumatic valves, and is controlled by a PLC controller. The addition is performed according to a set schedule and sequence, with the aim of increasing the carbon dioxide content and decreasing the oxygen content in the deoxygenated water.
• CIP control unit: The unique design of the packing tower makes it challenging for traditional cleaning techniques to adequately address equipment maintenance issues. In mild cases, scaling may impair the functionality of the mass transfer column, while in severe cases, it could lead to contamination issues and unpleasant odors. The automated CIP procedure ensures the tower remains clean throughout the process, avoiding the buildup of carbonate-induced sediments. In addition, the biological indicators in the dilution water meet the standards for pure draft beer.
