As part of an overall facility upgrade this
major oil refinery decided to seek ways of
reducing its heavy oil pre-heating costs.  A
proposal was submitted that would
enable waste heat from the refinery to be
used as the source to safely pre-heat the
stored heavy oil. The solution proposed
the use of a gas to water recovery unit
coupled to two superconductor-based oil
pre-heaters connected directly to the exit
points of the heavy oil storage tanks.

The solution offered 2 significant benefits
over traditional direct fire burners:

1.  Safety – The oil pre-heaters are heated
by hot water and offer no possibility of
ignition as in the case of traditional direct
fire burners.

2.  Cost Saving – As the heat source is
waste heat the oil is pre-heated at no fuel
cost.  Also the design of the oil pre-heater
itself is optimized so that only the oil
exiting the tank is heated thus avoiding the
need to pre-heat the static content of the
storage tank.

The proposed solution was implemented
in phases and with minimum disruption to
the plant and has fulfilled all the objectives
set for it and more.

A significant additional benefit is the low
maintenance requirement of the oil pre-
heater.  Its simple structure and passive
nature allow it to operate with minimum
ongoing maintenance thus further
reducing ongoing operating costs.
