The report gives results of continuous compositional monitoring by process gas chromatography (GC) for three gas streams associated with the Selexol acid gas removal system at the Bi-Gas pilot plant in Homer City, PA. Data were obtained from the inlet and outlet streams of the Selexol system during tests in April and May 1982. Product gas composition data were logged for 55 hours of plant operation. The Bi-Gas pilot plant, utilizing a two-stage, entrained-bed, high-pressure slagging gasifier, produces a product gas that is low in tars and heavy oils. This gas stream required very little cleanup prior to instrumental analysis. However, some problems were encountered in the analysis of the Selexol acid gas stream due to the presence of high levels of naphthalene. The process gas chromatographs performed well and remained very stable during the tests. Material balances based on GC analyses and process flow rate data show a high degree of material accountability. The H2S removal efficiency of the Selexol absorber was about 99% during the tests.
