Acid gas scrubber with wash solution recycle
Acid gas scrubber with wash solution recycle
(OP)
Greetings everyone.
This is my first post here, but let's go straight to business.
I am starting to work for an engineering company and my first project is to design a scrubber to remove HCl and SO2 from tail gas.
The customer wants to use 10% NaOH in water with recycle of the wash solution; liquid flow will be something like 30 times bigger of the stoichometric minimum.
How can I calculate the steady-state concentration of sodium chloride and sodium sulphite in the wash solution?

Do you have aspen plus process simulator? Look the document.

But I found a solution in the meantime.

Would you care to share with us, the forum members you asked for help, what is the solution you found? Perhaps it could be useful to someone else.

Thus, steady-state concentration is controlled by the recirculation ratio.
