Processing light naphtha. the last virgin
Methods for improving the octane number of light straight-run naphtha, necessitated by the lead phase-down, involve either the conversion of straight-chain molecules to their higher octane branched isomers or their removal from the stream. Isomerization can be achieved by Shell Research B.V.'s Hysomer process which is a once-through process that can be adapted to an existing idle hydrotreater, catalytic reformer, or other hydrotreating unit, and which yields a 79-82 clear research octane at a C/sub 5/+ liquid yield of 97-98%, dependent on feedstock type; or by Union Carbide Corp.'s TIP (Total Isomerization Process), which yields an 88-92 clear Research octane at a C/sub 5/+ liquid yield of 95-97%. Normal paraffins can be removed by Union Carbide Corp.'s IsoSiv process, which can increase the octane of the C/sub 5/-C/sub 8/ stream by 15 numbers and yields normal paraffins for petrochemical feedstocks. The technology, performance, operating experience, and costs of these processes are discussed in detail.
