Basics
- A Device that "Upgrades" Biogas to the same quality and roughly the same standards as Natural Gas, thus allowing it to be used with the existing infastructure such as CNG
- May reduce damage caused by H2S if present in the biogas\
- This could also produce dilute sulphuric acid
- Supposedly steel wool works well as a scrubber (or more likely in our case as a failsafe) for hydrogen sulfide)
Industry Standards
Existing Open Source Designs
- This Wet Scrubber + Electostatic Precipitator Combo
- An Indian Design Utilizing Rotary Contactors (Don't entirely understand it yet, need to look into it)
Minimum Viable Product
- Modular
- Removes H2S and CO2
- Has a low pressure out feed with quick disconnects to connect to other devices such as a Natural Gas Compressor
Design Research
- From Wikipedia:
Water washing The most prevalent method is water washing whereby high pressure gas flows into a column in which the carbon dioxide and other trace elements are scrubbed by cascading water running counter-flow to the gas. This arrangement can deliver 98% methane with manufacturers guaranteeing maximum 2% methane loss in the system. It takes roughly between 3% and 6% of the total energy output in gas to run a biogas upgrading system
So essentially a simple wet scrubber
