Application of the Self-Heat Recuperation Technology to Deisobutanizer Column

Abstract

Abstract-An innovative self-heat recuperation technology, in which not only latent heat but also sensible heat is circulated in the thermal process, was studied and applied to the deisobutanizer column. To determine the amount of energy required for this technology, ASPEN HYSYS was used. According to the simulation of the proposed sequence, the condenser duty and reboiler duty were saved up to 73.43 and 83.48%, respectively as compared to conventional column.
