Techno-economic analysis of heat pumping technology for oleochemical fatty acid fractionation

Distillation unit is often known as a major energy consumer in chemical refineries. Recent researches have shown an increased interest in heat pumping technology. So far, previous studies of heat pump integrated column have not dealt with industrial oleochemical separation. The aim of this research...

description Distillation unit is often known as a major energy consumer in chemical refineries. Recent researches have shown an increased interest in heat pumping technology. So far, previous studies of heat pump integrated column have not dealt with industrial oleochemical separation. The aim of this research paper has therefore been to investigate the implications of using heat pumping technology on oleochemical fractionation. This work takes the form of an industrial case-study of palm kernel oil (PKO) fatty acid fractional distillation. Two different arrangements of mechanical vapour recompression (MVR); namely direct vapour recompression (VRC) and bottom flashing heat pump (BFHP), were introduced to the process and their performances were assessed for technological efficacy as well as cost effectiveness.
