摘要
根据某石化总厂生产过程控制23套在线气相色谱仪中柱切系统国产化的实际需要，在气相色谱专家系统研究的基础上，通过选择正确的柱系统，并采用基于反吹、前吹、中心切割等基本柱切方法为基础的组合式柱切技术，配以往长、流量、流动方向和柱温的调节，取得了圆满成功。实际使用证明，所研制柱子的性能达到日本原装柱的水平，寿命为1～3年不等。
According to the home-made requirement of column switching systems in 23 industrial gas chromatographs in 300 000 Tons of olefin plant, based on the research work of the expert system on gas chromatography and movement laws of compounds of interest in columns, the suitable stationary phases were defined, and the column switching systems were designed by using combined cutting techniques which consist of backflushing, fore-flushing and heart cutting, and by controlling column lengths, flows, now directions and temperatures. The practical applications showed the column systems satisfy the on-line monitoring requirement of the production process and can be used continually for 1～3 years.
