Production of acetylene from natural gas: the issue of online oxygen measurement
Thread Content
In the process of producing acetylene from natural gas, it is necessary to measure the oxygen content in higher alkynes online. How is this done? The oxygen concentration is around 0.5%; the mixture contains 50% hydrogen, 5.7% nitrogen plus argon, 24% carbon monoxide, 3% carbon dioxide, 2.1% methane, 0.7% acetylene, 5.8% saturated water vapor, 5% 1,3-butadiene, 1.8% vinyl acetylene, and 7.3% diacetylene. The problem is that the higher-order alkynes in the subsequent reactions are very unstable, and sampling for analysis can easily cause blockages in the sampling pipes. Seeking experts to suggest a solution

It’s a top-laser through-type design, without a sampling probe. It won’t get clogged. What are your temperature and pressure?
