Hello,

I am building a simulator with Simulink (MATLAB). I need to simulate a photobioreactor and there is carbone dioxyde involved (the phytoplancton culture does photosynthesis in order to grow). It enters in the photobioreactor in gaseous form at 20 mL/minute. I need the mass-balance equation for the CO2 uptake. In this equation there is a therm called the «CO2 saturation concentration» (I don't really know it is). I don't have a huge background in chemistry. I don't know if it's a constant or a variable and I don't know how to find and/or calculate it. It seems to be in relation with the Henry's Law. The liquid in the photobioreactor is mostly a replica of seawater. Hope to hear from someone soon!

Thank You.

Regards,

Pierrest

Hello pierrest,

Here is a CO₂ solubility curve in water.



I hope this helps,
