Issues with feeding flammable and explosive organic solvents in barrels
Thread Content
The reaction process currently involves the feeding of solvent in barrels; substances like hydrazine hydrate are flammable and explosive and cannot come into contact with air. So how can they be added to the reactor? We are considering using quick connectors, but the manager says that would require opening the lid to replace the connectors, and we need to ensure safety and a good seal. Does anyone have any suggestions?~~
A barrel pump or diaphragm pump can be used for feeding, but absolute sealing cannot be achieved.
When using hydrazine hydrate, one needs to be careful. Consider using nitrogen pressure to feed the material into the reactor; generally, there is a surge tank available for this purpose. You can feed the material from buckets directly into the reactor. It’s recommended that the person performing the manual operation stay away from it. . . :lol
The main issue is how to open the lid and connect the pump; this process must be carried out under nitrogen protection. I recommend purchasing a nitrogen tank, gloves, a transition chamber, as well as an oxygen detector. When opening the cover and connecting pipes, etc., all operations are carried out inside a nitrogen cabinet under nitrogen protection, mainly to ensure greater safety.
Because the amount of material used at one time is relatively small – only a few dozen liters – the manager felt it was unnecessary to use a high-level tank; the material comes in barrels~
It’s exactly this issue; I think the same way, but the manager believes that this approach doesn’t guarantee safety~~
I’ve also thought about nitrogen cabinets, but they’re not commonly used in industry, right? Is there anyone who specializes in making them?
The amount used per time is relatively small; if production is to be carried out on a long-term basis, it becomes important to design a feed system using a sump. Unloading from the barrel every time is very dangerous; the unloading and loading processes should have been considered during the design phase. The lack of a systematic approach in fine chemical design is also a problem; in many cases, only a rough design is done, making it impossible to carry out batch operations.
This product is manufactured for only a few months each year, so the management felt it wasn’t necessary to use many measuring tanks or anything similar. At first, I planned to use measuring tanks for feeding the material; however, the management decided to use barrels instead, as the raw material already comes in barrels. Even if there were a surge tank, pouring the material from barrels into that tank would still present the same problem
I’m not sure what kind of bucket you mean – how many liters is it? Such devices do exist and can be customized.
It’s the common type of solvent tank with a capacity of 200 Kg
