Solvent-refined-coal (SRC) process. Determination of trace hydrocarbon, sulfur, and nitrogen compounds in SRC-II process development Unit P-99 gas streams. [Impure hydrogen in recycle gas and low pressure gas processing]
A knowledge of the identity and concentration of trace hydrocarbon, sulfur, and nitrogen compounds in the various gas streams of the SRC-II Coal Liquefaction Process is needed in order to design the recycle gas purification and low pressure gas processing systems in large-scale plants. This report discusses the results of an experimental study to identify and quantify trace compounds in the various high and low pressure gas streams of SRC-II Process Development Unit P-99. A capillary column trace hydrocarbon analysis has been developed which can quantify 41 hydrocarbons from methane to xylenes in SRC-II gas streams. With more work a number of other hydrocarbons could be quantified. A fixed gas analysis was also developed which can be integrated with the hydrocarbon analysis to yield a complete stream analysis. A gas chromatographic procedure using a flame photometric detector was developed for trace sulfur compounds, and six sulfur compounds were identified and quantified. A chemiluminescence method was developed for determination of NO and NO/sub 2/ down to 10 ppB in concentration. A gas chromatographic procedure using an electron capture detector was developed for HCN analysis down to 5 ppM. Drager tube analyses gave semiquantitative data on HCl and NH/sub 3/ content of the gas streams.
