ON-LINE ANALYSIS OF ETHYLENE FURNACE LIQUID FEEDSTOCK

摘要

Ethylene furnace liquid feedstocks typically consist of naphtha range petroleum fractions. These petroleum fractions are complex solutions of n-paraffins, iso-paraffins, olefins, naphthenes and aromatics. Analyses that provide detailed data regarding types and concentrations of each compound present can be used to optimize furnace operations. Typically, liquid feedstock analyses are performed off-line in the laboratory. In order to provide more frequent analyses thus maximizing the opportunity for furnace optimization the laboratory analysis was placed on-line.
