December, 1999. A BP
refinery in The Netherlands has licensed Tai-Ji ID.
November, 1999. Exxon has
carried out a multivariable and partial closed-loop identification on one of
their units using Tai-Ji ID technology. The model quality is very good. Both
test time and the time of data analysis are cut considerably when compared with
a conventional method. Based on this result and the result at Mobil Oil,
ExxonMobil is interested to license additional Tai-Ji ID copies.
August, 1999. Mobil Oil has
used Tai-Ji ID for the identification of an FCC unit. When compared to a
previous identification using traditional approach, Tai-Ji ID technology has
cut test time considerably and model quality is very good.
August, 1999. Dow Benelux in
The Netherlands has carried out a partial closed-loop identification of a
deethanizer. Tai-Ji ID technology was used. The test lasted few days. The model
