Construction and Design
The Wetted Wall Gas Absorption Column ReaktiLabX 16 consists of a wetted wall column made of glass, 900mm in height with a 32mm internal diameter. A deoxygenating column made of clear acrylic is 1570mm in height with a 26mm internal diameter and a range of 600~5,000 ml/min. Water flow is regulated using a flowmeter with a range of 1~7 l/min. Air flow is regulated with a range of 0.1~1m3/h. The deoxygenator feed pump operates at 20 l/min at 2m head. The absorption column feed pump operates at 10 l/min at 1m head. The air feed pump operates at 24 l/min at 1 kg/cm2. The sump tank has a capacity of approximately 40l. An oxygen meter measures saturation, concentration, and temperature. Saturation is measured over a range of 0-199.9% with ± 0.5% accuracy and 0.1% resolution, with automatic temperature compensation from 0-50°C. Concentration is measured over a range of 0~19.9ppm with ± 0.2ppm accuracy and 0.1ppm resolution, with automatic temperature compensation from 0-50°C. Temperature is measured over a range of -100°C to +200°C with ±0.3°C accuracy and 0.1°C resolution. This construction allows the wetted wall gas absorption column to demonstrate controlled liquid film absorption using deoxygenated water and nitrogen sparging.
