Control of higher alkynes in purification process of acetylene in natural gas to acetylene plant

The purification process of acetylene and the principle of removing methyl acetylene, 1,3-butadiene, allene and other higher alkynes from acetylene were introduced, and the factors influencing the purification process were analyzed. Based on the analysis, the measures for controlling the level of higher alkynes in acetylene were proposed and implemented, which ensured that the acetylene purification unit could run in high load, long period and stable operation.
