Acetylene outlet pipeline: phosphine detected; severe dust accumulation, which has a significant impact. Where lies the problem?
Thread Content
At present, we have a pipe for detecting phosmet connected to the first floor in the main outlet pipe; the problem is that the output color is grayish-black. Upon comparison tests, using water for blowing yields the same result. 1. When measuring the purity of acetylene gas routinely, will the purity be affected if phosphine is present? It’s usually around 99.50%; what I mean is that the level of purity can indirectly indicate whether phosphine is present.2. There is dust in the acetylene gas, and it turned out that it wasn’t very pure even after passing through the neutralization tower. I thought there might be moisture in the acetylene gas, but I’m still confused as to whether the dust comes from the inner lining of the pipes or from the acetylene gas itself
I would like to ask whether phosphine is one of the factors that affect the purity of acetylene gas?
