Feasibility Study on the Replacement of Traditional Heat Exchanger by ALFA LAVAL COMP ABLOC in PETRONAS OPUs.

Selection of a heat exchanger for a certain application is a considerable decision
making. The performance of the selected heat exchanger should meet the maximum
demand of the operation unit involving the heat exchanger and also the cost factor is
of high importance since it consist the maintenance and the running cost.
In the present work, analysis had been carried out to investigate the possibility of
replacing existing traditional heat exchanger with compact types. The study is based
on the performance analysis to meet the operational requirement of PETRONAS
OPU. Also a cost analysis has been conducted to compare between the traditional
and the compact heat exchanger.
The results obtained have shown that COMPABLOC require less heat transfer area
than the STHE at the same thermal duty. On the cost analysis part, the analysis
reveals that the replacement is feasible and justified.
