Abstract
The properties of a dedicated infrared analyzer for
on-line measurement of the
oil content of water, the Oili analyzer, are evaluated
theoretically and with
laboratory measurements. The analyzer was originally
developed for controlling
the discharge of ballast and bilge water from oil tankers
and more than 200
such instruments have now been supplied for that purpose,
representing about 10
% of the total market. Some technical improvements are
suggested, and the
improved instrument is shown to be capable of measuring
oil in water to an
accuracy of__+20 % down to a detection limit of _+5 -
10 ppm in the presence
of high concentrations of interfering components and
under varying
environmental conditions. This opens up new potential
applications for the
instrument, e.g. the monitoring of water discharges from
oil and gas production
platforms. The infrared analyzer responds only to the
dispersed oil fraction,
and if the dissolved fraction is of interest as well, the
instrument must be
equipped with a UV option, as suggested here.
