Using sulphuric acid as motive fluid in ejector
« on: November 11, 2017, 04:23:45 AM »

I work in fertilizer industry. Sulphuric acid is being used in bulks. In some improvement schemes I want to introduce air into the system using an ejector. The motive fluid available is 98% sulphuric acid. But I have no idea whether such acid has been used in any chemical industry for such purpose.
Your suggestions and information are most awaited..

I want t9 know if i can use sulphuric acid as motive fluid in ejector...
I found relatively more viscosity and density than water it can give better ejecting effect.
Plz comment.
Even if not used in iindustry before.. isn't it going to work?

My gut feeling is that sulphuric acid would suck air... BUT:

Do you really really want to let a strong acid spurt around? Every process or apparatus goes wrong at one time or an other. It this case it sends acid on the workers and the hardware.

Would a more delicate and caring process do what you want? Let fine acid droplets fall gently through air within a protective container, or inject air bubbles in the acid. Let the acid flow on solid surfaces at air contact. Could that do the trick for instance:

Its a sulphuric acid manufacturing unit and air is introduced for final converter to increase performance. In the process there are strong sulphuric acid circulation pumps. I am aiming to utilize this circulation applying ejector to suck air. As per my knowledge, higher density n viscosity of motive fluid will enhance the suction of air
