Dear all,

I have a reactor in which 643kg/h of 4% acetone in 30 % HCL, ( ie 26kg/hr acetone and 617kg/hr of 30%HCL ) is fed along with 2010kg/hr of another organic mass. The organic mass contains 1162kg/hr Ethylene Dichloride and other high boiling components. the reaction takes place at 75oC under atmospheric pressure. my doubt here is how to calculate the HCL vapor loss as this HCL vapor quantity is required to design a HCL scrubber.

Hi,

 

 Kindly furnish details for HCL Reaction & function of HCL in your reaction.

 

 

Also mention phases of each reactants / products with Stoichiometric Coefficient.

 

 

This will help to estimate HCL Vapor loss quantity & help to design HCL Scrubber.

 

 

Regards,

 

SP

Hi,

 

Thank you for showing interest in my problem.

 

I cannot disclose the name of the main component as its confidential. I will just call it by name A, B , C, D. its a high boiling component and doesn't have interaction with any others i hope we can continue even without its name. Main components of vapor are EDC, HCl, acetone and air.

 

Here A + HCl  --->  B+ C and

C+acetone ----> HCl+ D. 

 

A, C are high boiling and D is a solid. All other components are in liquid phase only.

 

Thanks and Regards

Divya

hi ,

a)Just curious why don't you consider to recover the HCL vapor ?

 

 B) if you perform a mass balance on HCL   , you should be able to know what is needed for the reactions .

What you need to add is to compensate the losses !

 

my view
