I have been reading about the advent of cavitation as a technique. It claims to offer a number of advantages to biogas plants, but at the moment there is very little independent research material.
The claims range from reducing viscosity and therefore reducing the parasitic load of the plant by cutting back the amount of stirring, to breaking down the cellulose structure of rye silage and even straw. The claim is that as a result the gas yield per tonne of feedstock increases by up to 15%, and the retention time is reduced, presumably as a result of the surface area increasing.
The catch is that the cavitator uses a fair amount of power, and it also produces heat. In the summer months this is a concern as we don't want the temperature getting much over 40-42 degrees in the tanks.
Has anyone installed one yet.
Our second challenge is that we want to find a way of increasing our CH4 in the biogas. Our Feedstock is 65% maize silage and 35% rye silage, the resulting gas is anywhere from 51.5 to 52.5% CH4. Our aim is to increase this to 60%, which will enable our gas upgrade plant to process more and so inject more bio-methane into the grid. One option is to install some kind of pre treatment of the feedstock to drive off some of the CO2. Has anyone installed a hydrolyser, and what are the advantages and drawbacks. Can anyone recommend someone to speak to. Many thanks.
