Nitric Acid Storage

[doomster]

I have a project regarding nitric acid storage. Attached to this thread is the existing P&ID of our nitric acid storage. We planned to add a new storage tank which is bigger than the existing. Is it okay that we eliminate the intermediate tank?
And is it better to have the storage tank first rather than the intermediate tank?


Thanks!

Dear luffy13,

If there is a leak in the new bigger storage tank, then there is a total shutdown. The intermediate tank can help to run the plant at least for one shift while you repair the storage tank.

Dhurjati Sen,

Thanks for your reply. I planned to removed the intermediate tank and replace it a bigger tank so that there will be no major changes in the P&ID. If there will be three tanks then it will complicate the P&ID and additional cost because it will require new pipes and pumps.
Another question will be, what will be the optimum fluid level of the nitric acid for the level indicator need to be alarm.

Luffy

Dear luffy13,

Normally there is a definite consumption pattern and these tanks are filled regularly by tankers. Alarm is not compulsory.
