Questions about activated carbon
Thread Content
I would like to ask everyone: when we install activated carbon inside the reactor, many particles of activated carbon remain floating within it. If an open flame appears inside the tower at that time, could an explosion occur? I’m very worried about dust explosions!
It depends on the particle size and concentration of the activated carbon; if the explosive limit is reached and there is an open flame, a dust explosion may occur. In such cases, measures should be taken during installation to prevent the spread of activated carbon or to avoid open flames.
I agree with what Lou Shai Chuan Mingyue said; appropriate measures can be considered to avoid this situation. Possible measures include: 1. Preventing the generation of dust, for example, by installing temporary ventilation and filtration systems to remove dust suspended within the equipment; 2. Strictly controlling sources that could lead to sparks, such as ensuring that all operators wear protective clothing that meets safety standards, using anti-static tools, and implementing anti-static measures like proper grounding of adjacent equipment
Hehe, thank you all. After we installed activated carbon in the container, the client suddenly asked us to weld one of their own devices onto the reactor! To account for the possibility of dust explosions! I’d like to ask everyone for advice
It is possible to consider removing the part that is to be welded, welding it, and then putting it back in place. Generally, it is not allowed to perform welding work on the reactor when there is a catalyst present!
It is necessary to check the oxygen level inside the reactor; this level should be kept below 5%
It is strongly required that the manufacturer remove the equipment after emptying the reactor, or implement on-site isolation and protection measures. Under normal circumstances, no changes to the process or equipment are permitted after the reactor has been filled.
Activated carbon can be so scary; I never thought of that before. We only have activated carbon filters, so we should also consider this aspect.
