1. A system for capturing a constituent gas from a gas supply comprising:
a capture reaction vessel;
a reaction media configured to extract the constituent gas from gas flowing through the capture reaction vessel and to capture the constituent gas, and wherein the reaction media consists of a solid composition;
a housing inlet configured to receive a gas stream from the gas supply and feed the gas stream toward the capture reaction vessel;
a housing outlet configured to return the gas stream exiting the capture reaction vessel back to the gas supply, wherein a volume of the capture reaction vessel in which the reaction media resides directly connects to the housing outlet;
a first gas sensor proximal the housing inlet and configured to output a first signal corresponding to a first concentration of the constituent gas from the gas stream entering the housing inlet;
a second gas sensor proximal the housing outlet and configured to output a second signal corresponding to a second concentration of the constituent gas from the gas stream exiting the housing outlet;
a first gas flow sensor proximal the housing inlet and configured to output a third signal corresponding to a first gas flow rate of gas from the gas stream entering the housing inlet;
a second gas flow sensor proximal the housing outlet and configured to output a fourth signal corresponding to a second gas flow rate of gas from the gas stream exiting the housing outlet;
a controller including a processor to execute computer-readable instructions to perform functions of:
estimating a constituent gas absorption rate by the reaction media based on a difference between the first signal corresponding to the first concentration of the constituent gas and the second signal corresponding to the second concentration of the constituent gas;
estimating a gas flow rate based on the third signal and the fourth signal;
estimating a total mass of constituent gas absorbed by the reaction media during a period of time based on the constituent gas absorption rate and the gas flow rate; and
generating and transmitting a notification to replace the reaction media based on the total constituent gas absorbed by the reaction media approaching a constituent gas capacity of the reaction media, and
a fan configured to influence the gas stream from the housing inlet, over the capture reaction vessel, and through the housing outlet.
