Solvent-Refined-Coal (SRC) Process. Identification and Quantification of Trace Hydrocarbons in SRC-II PDU P-99 Gas Streams

摘要

Qualitative and quantitative determination of trace components in the key gas streams of the SCR-II Process is needed in order to design the gas purification and recovery systems in the Demonstration Plant. The objectives of the work described in this report were to develop an analytical procedure for trace hydrocarbon analysis and then to identify and quantify the trace hydrocarbons in selected gas streams of Process Development Unit P-99. A single column chromatographic method was developed which could detect compounds present at levels as low as 5 ppM (mole). Twenty-eight hydrocarbons have been positively identified and quantified, and a number of other hydrocarbons have been tentatively identified.
