Sodium Bisulfate - NaHSO4 Reactor Design

[erdyne]

Dear Colleagues,

I would like to design a continuous reactor for the production of Sodium Bisulfate melt with immersion burner which will keep the reactor temperature over 240 C, continuously agitated and sulfuric acid (1700 kg/hr 98% conc. 1.8 gr/cm3 density) and sodium chlorine (1000 kg/h) fed and also would like to be adding some bleaching additive to the discharging Sodium Bisulfate melt. I was more specialized in sulfuric and phosphoric acid production, so, could you please advise me a starting point or any useful reference document? Many thanks in advance

I recommend start with H2SO4 corrosion chart at elevated temperature. What do you consider this vessel&internals will be made of?
Looks like a rocket science.

It looks like we will brick line both acid preheating vessel and reactor.
I need to find out what kind of heat exchanger we need to use for preheating H2SO4 up tp 190 C while cooling the NaHSO4 melt down.

Advice - have a look to materials suitable for such combination of temperature+concentration. It looks like equipment cost will be overpowered. You should doublecheck if NaHSO4 price will justify such high capex.

Update
Beware of engineering this kind of

Erdyne,

Not sure who you work for, if full plant, but generally, just contact Chemetics for the acid preheater. That is their thing.
