Abstract: By taking the hydrogen composition measurement in reactant of polypropylene plant as the example and combing the practical application with the applied experience, this paper aims to introduce briefly the lectotype of industrial chromatograph, the sampling of analysis process, and the design and application characteristics of pretreatment system. The paper also describes the lectotype of industrial chromatograph and design ideas, and proposes the design and installation considerations of a typical process analysis system. In addition, it provides a reference for the design, upgrade and modification of process analysis system for other projects in the future.

Key words: Process analysis; Industrial chromatograph; Sampling ystem; Pretreatment system; Measurement principle; Lectotype;Installation
