Hcl Vapour Through Saline Solution
#1
Posted 27 June 2016 - 05:25 PM
A 7200L tank containing 16% HCl has an overflow which goes through a seal pot containing approximately 9L of Saline solution.
I've been asked to calculate the % of Saline required to strip the HCl vapour so none is released to atmosphere.
As there is no reaction I'm a bit stumpedulate the percentage of NaCl in water needed.
Can anyone advise?
Kind regards,
Ryan

Ryan,
Normally you need to use lime milk (calcium hydroxide) or soda ash (calcium carbonate), but if you storage temperatura is low the HCl (16%) is low (minimal evaporation).
In extreme you can use sodium hydroxide.
I attached information.

Can I assume that you have had some coursework and computational resources to deal with electrolyte thermodynamics? The basic approach to the scenario that I would expect would be to use your favorite thermodynamic model for electrolytes (Debye-Huckel is the one I am most familiar with, but there are others) to compute the impact of NaCl on the activity coefficient (and partial pressure) of HCl. Are you already familiar with (or have access to a computer program or colleague who is familiar with) these computational models and schemes?
