Many of us are using the citric acid and soda co2 reactor. I am also also running a setup for past 2-3 days and observed some points from which I concluded that the output is controllable but not constant. I may be wrong but I need other's observations and advices to make this setup even better.
My logic as well was practical observations:
1. Bottle A is mixed with 200gms citric acid and 600ml water. Bottle B is mixed with 200gms soda and 200ml water.
2. After adding all the equipments and keeping the needle valve or ball valve closed, we need to squeeze the bottle A and citric acid flows into bottle B containing soda. As soon as both of them react co2 is produced and some amount of co2 or soda mixture(CORRECT ME HERE,WHETHER IS IT CO2 OR SODA THAT BACKFLOWS) flows back to bottle A. Pressure in both the bottles increases and i think pressure in bottle A is a bit higher than that of bottle B(CORRECT AGAIN IF ITS INCORRECT). Now we can open the needle or ball valve when the pressure reaches 15-20 PSI or 1-1.5 kg/cm3.
3. As soon as we open the co2 flows from bottle B to tank and we can adjust the bps with needle valve.
4. Now after some time when co2 production slowly depletes in bottle B(CORRECT WHETHER CO2 PRODUCTIONS GRADUALLY DECREASES WITH TIME) the output will keep on decreasing and due to this decrease in pressure in bottle B citric acid flows from bottle A to B to make adjustments in pressures. And as soon as the citric again reacts with soda, co2 produces and the output slowly increases.
Now here's my point. At some point of time output starts decreasing and then again it will increase. Therefore a fluctuation on co2 output and thereby not consistent.
What you guys think of this?
