Title: Hydrocarbon content of the vapor phase and light-oil fraction in the output stream of the METC gasifier. [Tenax GC for adsorption of higher molecular weight hydrocarbons]

Abstract

The higher molecular weight hydrocarbons contained in the clean low-Btu gas are primarily benzenes and naphthalenes with some furans and thiophenes. While analysis of the data shows that loadings range from 1-10 g/scm, the data are subject to variability introduced both in the process itself and in the sampling methods. Qualitatively, for the higher molecular weight hydrocarbons, collection on Tenax at atmospheric or gas stream pressure gives similar compounds, although the distribution is different. Comparison of the pressurized Tenax, atmospheric Tenax, and the drip leg sample shows a decreasing amount of lower molecular weight components. This is due primarily to the collection method. In the latter two samples the pressure reduction can result in the loss of the lighter weight hydrocarbons that could be retained in the pressurized sample. It appears that, qualitatively, typical compounds in the gasifier stream have been identified. Quantitatively, additional studies need to be conducted to evaluate Tenax as a collection medium for pressure applications including the pressure dependency of its collection efficiency. It does appear that the pressurized collection of material using Tenax and the subsequent analysis by capillary GC/MS and headspace gas chromatography of the collected samples is a viable approach to acquisition ofmore » base line data for in situ hydrocarbon measurement system development.« less
