Where does carbon dioxide gas come from in acetylene plants?
Thread Content
Dear teachers and experts, regarding the neutralization tower in the acetylene plant, the relevant instructions state that it is used to neutralize carbon dioxide in that plant. However, I don’t see any formation of carbon dioxide in the reaction equations provided earlier. Could you all give me a detailed explanation?
During the calcium carbide feeding process, air is also introduced, and one of the components of air is carbon dioxide.
During the charging process of calcium carbide, we use a two-stage hopper replacement method; it can be assumed that the carbon dioxide content in the hopper after replacement is negligible This part should be minimal, right? Does Teacher Du know of any other ways?
You’re right, it’s very rare. Additionally, there are also extremely trace amounts of carbon dioxide in nitrogen.
During the production of calcium carbide, a large amount of carbon dioxide gas is trapped within it; this is the main issue. Additionally, carbon dioxide may be generated in the acetylene system (there is no relevant literature on this matter, and this issue should be addressed with the PVC department)
