用工业色谱仪对石油裂解气进行线上分析的关键问题在于采样装置。有的文献报导,工业气体分析中的问题,大约有85％出在采样装置上。一个好的采样装置,必须满足以下要求: (1) 采集的样品能代表过程中混合物的组成。
The key issue with the industrial chromatograph on-line analysis of pyrolysis gas is the sampling device. It has been reported in the literature that about 85% of the problems in industrial gas analysis are on samplers. A good sampling device, you must meet the following requirements: (1) collected samples can represent the composition of the mixture in the process.
