Résumé:
The present work has the objetive to study the economic viability of the
ethylbenzene-etyrene separation through the one heat-pump connected to a conventional
distillation column. The work is divided in three parts: optimization of the conventional
distillation column, when payback period is adopted as the criterion; heat recoved from the
top of the condensation column through heat-pumps with vapor recompression and
intermediate fluids like water (R718) and methane trichloro (R20), and the analysis between
the operational and capital costs of the conventional and heat-pumps systems was
compared. It was done to obtain the optimal economics conditions for a destination with
heat-pump. The optimal operational parameters obtained from the conventional system are
the same for all distillation with heating pump systems studied. The results showed that,
both the heating pumps systems are economic alternatives to susbstitute the conventional
distillation system. Among the systems with heating pumps the vapor recompression has
showed the most suitable technic to heating recovery.
