Key Engineering Factors in BioCNG Plants

If everyone talks about economics, someone needs to talk about engineering. It is part of our responsibility being a technology provider for CBG/BioCNG Plants.

A quick list of critical engineering parameters related to Biogas. BioCNG, Compressed Biogas plant. This article has nothing about economics.

Raw Material

The raw material, the mix, the solids in it, proteins and carbohydrate in it, dry weight, cellulose, lignin, oil content - decides the size of a digester. This makes every plant different by itself. Some rule of thumbs work, which all of us tend to make it look simple. Using gravity to our advantage is also a prime consideration.

Layout

Layout eats away space, makes pipelines longer, strains workmen unnecessarily. A good and logical flow of the process, no criss-cross, enough space for the vehicle movements, storage spaces, buffer spaces per the safety norms, and blending the layout with existing buildings in case of an industrial captive plant is a key thing to keep in mind. A bad layout would look like patched jeans.

Piping

Gas has an abrasion value too. Too fast will erode the thickness of the piping, creating noise and vibrations. Every bend in the pipeline drops the efficiency of movement.…
