A smaller reactor mean lower capacity

There was a time when mobile phones were large because technology gave us no smaller alternative.
Then innovation changed what was possible.
Phones became smaller while their capacity, intelligence and functionality continued to grow.

The same principle applies to reactor design.
A compact reactor can simply mean that more of the space inside it is filled with organic material that produces biogas – instead of added water.
Every cubic metre inside a biogas reactor has a purpose.
In many biogas processes, water is added to make pumping and mixing easier – or even possible.
But added water does not produce biogas.
The plant still has to be built and operated to carry it through the entire process.
That means:
✔️ more reactor volume to build
✔️ more mass to heat
✔️ more material to move and manage
✔️ larger digestate storage requirements
✔️ more volume to transport or separate afterwards

When more organic material is processed per cubic metre, the reactor volume becomes more productive.
But productive reactor volume is not only about what goes inside.
It is also about how the material moves through the process.
In Arciplug®’s PLUG FLOW Multi Feed Digester, the material moves progressively through the reactor. This controlled forward movement keeps fresh feedstock from taking a shortcut to the outlet and helps ensure that the material remains in the reactor for the intended retention time.
By preventing short-circuiting and giving the biological process sufficient time, the reactor is designed to maximise the biogas potential of each feedstock.
The result is more than a smaller footprint.
