为了适应我厂尿素装置的技术改造,测量尿素合成塔气相出口气体组份浓度,引入控制在线分析,我厂采用了一台日本的Gc6工业色谱仪。这种型号的色谱仪操作方便、重复性好、数字显示,而且有微机处理及贮存,可根据指令自动打印组份浓度及保留时间;它可进行线性化处理、多项式计算、比值计算、总和补偿,递推滤波等。
In order to adapt to the technological transformation of urea plant in our factory and measure the concentration of gas components in the gas phase of urea synthesis tower, an on-line control analysis was introduced. Our factory adopted a Japanese Gc6 industrial chromatograph. This model of the chromatograph easy to operate, reproducible, digital display, and computer processing and storage, according to instructions automatically print component concentration and retention time; it can be linearized polynomial calculation, the ratio calculation, the sum of compensation , Recursive filtering and so on.
