I've been searching the posts here and I think this question may be a little below most of you.
I've cobbled together a homemade biogas generator and I'm wanting to improve the quality of the biogas by removing some of the CO2 (or all of it if I can) which will leave me with a higher calorific value gas (as the remaining gas is predominantly Methane) and possibly something which I could even burn in my standard gas boiler?
I know CO2 will dissolve in water, and I also know that if I add heat to the water it will liberate some of the CO2 dissolved (/reacted)
The questions are
How much heat do I need to input to liberate the CO2?
What temperature do I need to achieve, I'll be using waste gas from a condensing boiler so probably about 60 C is my limit?
What by-products will I produce either with or without releasing the CO2? (so I'll know what materials I can use)
Is it all worth the effort of should I just constantly replenish the water supply? (again by-products above will tell me if I can re-use the waste water for irrigation, or if I'll cause any problems by dumping it in the sewer, albeit as a constant low flow).
Would water saturated with CO2 actually be beneficial in the greenhouse (i.e. tomatoes not day after tomorrow)
I hope this isn't too simple for you guys out there, Chemistry is about twenty five years old for me!
