Abstract:

Crude distillation unit, hydrotreating unit, olefin plant and polymer plant are usually installed in refinery and petrochemical complex. Central laboratory is responsible for the analysis of feedstock, intermediate efflux, products and by-products. Gas Chromatography (GC) is one of the most important means of analyzing the composition of streams in petrochemical industry. GC is the equipment with the largest number in the central laboratory. In the engineering design stage, it is particularly important to configure GCs correctly and reasonably. Based on the experience of engineering design, this paper takes a refinery and petrochemical complex as an example to give some suggestions on the configurations of GC in central laboratory.

Key words:  , refining and chemical integration, central laboratory, gas chromatography/GC, configuration
