Regarding the issue of adding concentrated sulfuric acid
Thread Content
Hello everyone, I need help with a problem related to adding concentrated sulfuric acid. I need to add between ten and twenty kilograms of concentrated sulfuric acid into a reaction vessel – how should I measure and add it? How can it be made simpler and easier to implement? We want to add the material manually each time we weigh it and pour it directly into the tank (a certain amount of water is already in the tank; will pouring the material in cause splashing?). But isn’t such a method very dangerous? Also, can’t the emptied bucket be rinsed with clean water? Could some expert give me some advice? Thank you!
There are safety concerns, so I’d like to hear any good and proven suggestions from everyone
Sulfuric acid is added to the high-level tank and the reaction is carried out drop by drop; try to avoid manual operation
Indicate it based on the volume of the sulfuric acid tank. The tank should be equipped with a level gauge, and it’s necessary to calculate the mass corresponding to each scale. It’s best to carry out automatic feeding through a control valve. What is the concentration of your sulfuric acid?
Why isn’t there a high-level measurement tank for this? Carbon steel as the pipe material will suffice.
Adding risk manually is very dangerous; no matter how strict the penalty systems are, there is no guarantee that workers won’t suffer sudden setbacks. Peristaltic pumps or metering pumps can be used to add the substance in small amounts. Don’t rinse the empty buckets with water after use; they’re not worth much, and the money saved over a year isn’t even enough to cover the costs of treating an occupational injury
Measurement is carried out through a sump; during the dripping process, stirring and cooling are recommended
