ABSTRACT:

The use of the UOP/BP Cyclar(reg sign) process for upgrading Fischer-Tropsch (F-T) liquefied petroleum gas (LPG) was studied at UOP(reg sign). The Cyclar process converts LPG into aromatics. The LPG derived from F-T is highly olefinic. Two routes for upgrading F-T LPG were investigated. In one route, olefinic LPG was fed directly to a Cyclar unit (Direct Cyclar). The alternative flow scheme used the Huels CSP process to saturate LPG olefins upstream of the Cyclar unit (Indirect Cyclar). An18-run pilot plant study verified that each route is technically feasible.  An economic evaluation procedure was designed to choose between the Direct and Indirect Cyclar options for upgrading LPG. Four situations involving three different F-T reactor technologies were defined. The main distinction between the cases was the degree of olefinicity, which ranged between 32 and 84 wt % of the fresh feed. 8 refs., 80 figs., 44 tabs.
