Can the liquid chlorine in storage tanks or cylinders be directly fed into the absorption tower to react with the slurry?
Thread Content
I’ve run into a problem recently: the absorption tower used in my facility needs to use chlorine for absorption, and the operation takes place at atmospheric pressure. Is it possible to send the liquid chlorine stored in tanks through pipes to the bottom of the tower, where it can vaporize and then come into direct contact with the slurry for absorption? Initially, a coil-type vaporizer was considered, with hot water being used to vaporize liquid chlorine. Later, the owners wanted to save on equipment or for some other reason; they decided to feed liquid chlorine directly into the absorption tower (there is a distance of over 80 meters from the storage tank to the absorption tower). They thought that the liquid chlorine would vaporize there and then react with the slurry. It seems that this approach would be difficult to implement. Is there anyone who can explain how to perform this operation: handshake
A pressure reducing valve needs to be installed just before entry into the tower; at the same time, it is necessary to determine to what temperature the chlorine will cool down as a result of adiabatic pressure reduction by this valve, and whether the material can withstand such conditions
Have you actually applied this process where you are?
It must be chemical absorption; this approach is not feasible.
The owner wants to save trouble and is wondering if there are any measures that can be taken to achieve this:dizzy:
The direct use of liquid chlorine in reactions is prohibited; liquid chlorine contains nitrogen trichloride, and if this substance cannot be removed along with the reaction materials or decomposed, it may accumulate； Furthermore, liquid chlorine is far more reactive than chlorine gas ； The material may also be difficult to choose.
You must have practical applications in this area: for handshakes, what’s the appropriate way to respond? It would be good to have some guidelines or examples that outline what’s acceptable.
There are various regulations regarding the use of chlorine, set by national standards, safety associations, and chlor-alkali associations; there are several of them, so take a look.
I looked up information on several industries and found no details regarding the direct use of liquid chlorine. I asked other people, and some said that this liquid chlorine does not vaporize completely in the absorption tower; most of it remains in liquid form and flows to the bottom of the tower where it reacts with the liquid slurry there. This situation represents a change in the process, and it may require validation regarding the chemical reactions involved.
