Evaluación técnico económica para convertir una unidad de isomerización de butanos a isomerización de pentanos y hexanos

This paper describes the development of a simulation analysis of the transformation process and the changes in operating conditions required to convert a process unit that isomerizes n-butane to a unit that can also isomerize light naphtha (C5/C6). In order to it was necessary to evaluate the reaction kinetics of both processes, and the conditions to favor the isomerization of both n-butane and the paraffin of C5 and C6. The construction of the reactor’s simulation considering the kinetics, was fundamental for defining the performance of the unit under current conditions and opportunities for optimization, as well as the performance of the unit comparing with light naphtha (C5/C6) processing. In addition, the optimal operating conditions of the unit, the configuration of the reactors and determination of the use of recirculation was obtained to benefit the increase in the conversion, seeking an increase in the octane number RON (Research Octane Number) above 80. The simulation level allowed evaluating reactor capacity and space velocity (LHSV), hydraulics and heat transfer in heat exchange equipment, as well as the entire hydraulics and distillation profile of the stabilizer column, considering the top and bottom of the circuit. All this made it possible to identify bottlenecks and solve problems associated with raw material changes; It also allowed defining the optimum operating range without exceeding the unit's integrity windows, allowing a reliable and safe operation
