DeCarbonator

The DeCarbonator is designed for continuous adjustment and especially reduction of the CO₂ content of the product. CO₂ is used e. g. for neutralization of alkaline wastewater, pH adjustment and various chemical reactions.

The system is designed to continuously adjust the CO₂ content in a product to the required level. Highly efficient membrane modules allow the CO₂ concentration to be increased and decreased with extraordinary accuracy. At the same time the oxygen content is reduced. Each module contains thousands of hydrophobic, gas permeable hollow fibre membranes resulting in a large surface. This large surface maximizes the transfer area and the contact time between product and gas. While CO₂ is applied on the inside of the hollow fibres, the product flows in counter current between them on the outside. Depending on the CO₂ partial pressure difference between the product and the gas, the CO₂ permeates through the membranes either out of the membranes into the product or out of the product into the membranes. This fundamental scientific principle is described by “Henry’s Law”. The CO₂ content of the carbonated product is permanently monitored. Therefore, the system is equipped with a high precision CARBOTEC sensor made by Centec. Centec have decades of experience in the development and manufacturing of own precision instruments for CO₂ control. Based on this accurate in-line measurement, the carbon dioxide flow is instantly and fully automatically adjusted. The O₂ content is measured with proven Centec optical OXYTRANS sensor technology.
