This paper presents a methodology for optimising the exergy efficiency of atmospheric
distillation unit without trading off the products qualities and process throughput. The …

There exists three practicable crude oil vacuum distillation processes and different
processes have a significant impact on material and energy performances, including product …

Energy efficiency has become an important feature in the design of process plants with the
rising cost of energy and the more stringent environmental regulations being implemented …

Stability of crude oil distillation units was analyzed with mathematical models developed
using Aspen Hysys. Parametrical sensitivities of light fractions yields, heat duties and steam …

Engineering projects to increase the capacity of existing heat-integrated crude oil distillation
columns are commonplace. Retrofit projects aim to exploit the processing capacity of …

An energy‐efficient crude distillation unit (CDU) was proposed, and its performance was
evaluated and compared with that of a conventional CDU. The problem of the large energy …

A study of operability and assessment of the safety level of a crude distillation unit in a
Nigerian refinery has been carried out. In a crude distillation unit of a refinery, the desalter …

This paper demonstrates the Retrofit Design Approach (RDA) and Response Surface
Methodology (RSM) for the retrofit of industrial plants in which assessment of design options …

An energy-efficient crude distillation unit (CDU) with a divided wall column was introduced to
evaluate its performance compared to the conventional CDU. The large energy demand of …

In the present study simulation and optimization of a crude oil distillation unit of a refinery by
Aspen HYSYS simulation program has been carried out with the aim of increasing the …
