… in Terms of absorption rate with the Unique RITTER Dip Pipe System:
Better than 99% absorption capability and you don’t even need any absorption indicator!
Ordinary systems for CO2 absorption lead the biogas into the inside upper part of the absorption bottle, the gas thus wetting the absorption liquid surface. The achievable CO2 absorption rate is therefore much lower than the optimum of 100%, especially with higher flow rates and/or higher fractions of CO2. Advanced systems are operating with a dip pipe leading the gas into the absorption liquid. By bubbling the gas through the liquid, higher absorption rates can be obtained by the larger surface of the gas bubbles in contact with the liquid.
The ultimate advancement of dip pipe systems results in the unique RITTER dip pipe system
The biogas generated in the fermentation bottles flows through a dip pipe into the absorption bottle (»bubbler«) containing the absorption solution. The world-wide unique design of the dip pipe with a bell-shaped “absorption chamber” enables previously unachievable high CO2 absorption rates up to reaching the absorption limit through …
Another outstanding effect is the fact that the RITTER absorption system can operate without any absorption liquid indicator showing the limit of the absorption capacity. It is a general problem of such indicators that the colour doesn’t change abruptly but continuously. Therefore, it is difficult for the user to recognize the true limit of the absorption capacity. In contrast to indicator systems the RITTER system guarantees an absorption rate of at least 99% up to reaching the absorption capacity limit. This capacity limit will be indicated by the MilliGascounter by measuring of the volume of methane remaining in the gas stream after absorbing the CO2.
