Hi all,
For my job I’d like to compare two methods for disposing of Ammonia in an aqueous solution (26 Baume, 29.4 wt % Ammonia @ 65°F) as to achieve an ideal pH of 7. One method, which I have already modeled, is neutralization with Acetic Acid; another method may be to allow the ammonia in the 26 Baume to simply evaporate away by leaving a carefully positioned barrel exposed to atmosphere for some amount of time (possibly with the understanding that a modest amount of acid will need to be added to finish the job).
I have access to what appears like all the relevant data (Vapor pressure, density, etc.) but I’m not sure exactly how to formulate the governing equations. Before I attempt to derive my own governing equations, I’d like to know if this process (or similar ones) have already been modeled. If so, I’d love a link to the corresponding equations. If not, perhaps some of you more experienced Dopers can give me recommendations on how to model the process. Specifically, I’d like to derive an equation for the rate of ammonia evaporation as a function of time / environmental conditions (ambient temperature, wind velocity, etc.).
I am fairly certain that straight up neutralization of the ammonia with Acetic Acid will end up being the more practical / faster procedure, but I’d still like to learn how to model the evaporation rate (I’m a co-op student, still eager to learn shit).
Thank you all, and please let me know if there are any questions.
