An Approach towards the Design of a Petlyuk Column Using Hysys

Mustafa M.Abbas, Wilson J.A.


Distillation is considered one of the oldest unit operations. Throughout the years, chemical engineering designers have been working hard to reduce the energy consumption of columns which has led to the development of many non-conventional methods. Of particular importance are thermally coupled distillation columns (TCDC) which offer large savings in capital and operating cost. The main concern, when contemplating the use of TCDC, is the unavailability of easy and well established design procedures. Furthermore, some steady-state simulators have given convergence problems particularly to establish the first solution. Thus, this paper presents an approach for the design of the more complex Petlyuk column based on dynamic simulation using HYSYS.
