Our gas purification systems were already used in industry at the earliest years of foundation: this CO2 purification system with a capacity of 600 Nm³/h went into operation in 1983. After removal of ethylene oxide CO2 in food grade quality was produced. Nowadays ReiCat’s CO2 purification units with larger scales produce carbon dioxide for e.g. mineral water. This system has a capacity of 3000 Nm³/h, beside methane, ethylene and ethylene oxide are removed. Curious? Gas Purification - Englisch (reicat.de)
