Level measurement of Sulphuric acid tank
Level measurement of Sulphuric acid tank
(OP)
We a operating a 400 ton/day Urea manufacturing facility. At our water treatment section we are experiecing difficulity in maintaing level glasses and level switches of sulphuric acid(98%) tanks.
There sensing lines get chocked by sluge and we have to mesure the level by dipstick. One of our tanks overflowed due to overfilling caused by wrong level.
We would appreciate help on maintaing sulphuric acid tankks, Altrnates for reliable level measurements & standard arrangement for level measurement / tank protection.

An excellent guidleine for the delivery, storage and transfer of Sulfuric acid is on the internet. It was developed by "General Chemical":
See this link:http://www.genchemcorp.com/pdf/tsr5078.pdf
Generally speaking, either a manometer (bubbler) system, or a "weigh cell" system or an top of the tank mounted "ultrasonic" device are most often used. ( I recall that the company "Milltronics" has such devices.
You did not tell us about the concentration of acid and the tank material. Please post a response...
Your sludge may be from the acid consuming the tank walls ?!! ( a small amount of sludge is OK in a new tank)
Do you have a tank maintenance program and have you measured the wall thickness at the shell midpoint ??!!
Other sulfuric acid tanks have collapsed without warning....
Is your engineering field office downhill from the tank !!
Do you have a dessicant vent dryer installed ? These are highly recomended in order to prevent water ingress.
More details ....please
Good Luck..........

Try radar level sensor. We are using it for corrosive service. Great stuff.
