ABSTRACT:
Managing crude oil fouling has been a challenge in
PETRONAS refineries. Over the past several years,
numerous initiatives have been conducted in order to have
better control of the situation [1][2][3][4]. The control
strategy currently implemented is to periodically clean the
heat exchanger based on the heat exchanger monitoring
parameter and supported by antifouling chemical injection
program. A review was conducted in one of PETRONAS’
refineries in order to come up with a better fouling control
strategy. The review is separated into two parts.
Firstly, the plant operational data for two selected hot
pre-heat exchanger trains was analyzed. From the analysis,
deposition build-up is apparent for only one exchanger train
despite both trains receiving the same crude blend. It seems
that there are several significant parameters which caused
one of the exchanger to fall into fouling threshold region.
EXPRESS [5] software was used to evaluate the fouling
threshold region for the heat exchanger.
Secondly, foulant sample obtained from the heat
exchangers were subjected to analytical testing to
investigate the constituent of the foulant. The analyses show
that it is mainly organic in nature with a minor portion of
the inorganic content made up of mostly corrosion products,
salt and sand.
