天然气裂解乙炔,乙炔裂解反应在1 500℃,1~3 ms内发生,在此过程中副产物高级炔极易析出堵塞提浓系统管道、设备,如果不及时排出,聚合物在系统内逐步累积会造成系统堵死的严重后果。本文详细介绍了天然气裂解制乙炔副产物高级炔的处理工艺。经过对高级炔的及时处理,不仅解决了装置长周期稳定运行的问题,同时节约了管道、设备清理成本。
Natural gas cracking acetylene, acetylene cracking reaction at 1 500 ℃, 1 ~ 3 ms occurred in this process by-product of high grade alkyne easily precipitate plugging system piping, equipment, if not discharged in time, the gradual accumulation of polymer in the system Will cause the system to block the serious consequences. This article describes in detail the treatment of acetylene byproduct higher alkyne produced by natural gas pyrolysis. After the timely treatment of high-grade alkyne, not only solved the problem of long-term stable operation of the device, while saving pipes, equipment clean-up costs.
