Description
In oil refineries, the final composition of a
product is achieved by a special process
known as -inline blending-. The end product
is obtained by mixing various oil
qualities and additives continuously and
in precisely defined quantities. Due to
certain variables during this process,
such as reaction times in the control
loop, changed mechanical settings, contamination
of the control valves, or similar
disturbances, deviations from the
intended result can occur. These deviations
can be detected by integrating the
actual flow values, thus enabling the
set-values to be corrected by a corresponding
factor during the blending process.
As a result, the final product that
reaches the storage tank will have the
exact required composition.
The inline blending process is not limited
to oil refineries, but is also used in the
chemical and pharmaceutical industries,
foodstuffs and animal feed industries,
and in any other process where different
ingredients are mixed according to a defined
recipe.
