The article presents results of experimental analysis of alkylaromatics composition in paraffins dehydrogenation process feed flow. It was shown that during the technological stages, as a result of dealkylation and polymerization processes, these substances adversely affect the equipment. At the HF-catalyst regeneration stage their presence leads to compression of inter-draining period, as heavy aromatics accumulate mainly in the column bottom. In sulphonation reactor it manifests itself as viscous component formation, sulphonation uniformity disfunction and compression of inter-washing period. Recommendations concerning the processes optimization depending on alkylaromatics composition in the feed flow are provided.
