Aspen
Technology, Inc.
(NASDAQ: AZPN), the asset optimization™
software company, today announced that Zeeland Refinery, a joint
venture between Total and Lukoil in Western Europe, will deploy Aspen
GDOT™ dynamic optimization software.

Aspen GDOT will initially be deployed on the middle distillate
production units across the refinery and will help Zeeland Refinery to
drive more consistent product quality, increasing middle distillate
production and advancing energy efficiency.

The dynamic coordination of APC (advanced process control) for multiple
process units by Aspen GDOT can help optimize all planning and
scheduling opportunities to drive higher than previously expected
profitability in operations.

Nathalie de Muynck, general manager at Zeeland Refinery said: “By
implementing Aspen GDOT with our existing AspenTech APC platform we can
realize additional optimization capabilities that will further improve
profit generation, therefore delivering significant value to our
shareholders.”

John Koumoutsakis, senior vice president of sales at Aspen Technology
added, “We look forward to helping Zeeland Refinery further improve its
operational efficiency by deploying Aspen GDOT. With changes to
regulations such as the IMO
2020 Marine Fuel Specifications
that demand lower sulphur emissions
from marine fuel, the need to align planned performance with actual
performance is key to improving productivity levels.”

About Aspen GDOT
Aspen GDOT™ dynamic optimization technology
is a key part of AspenTech’s Unified Production Optimization solution
that enables customers to improve refinery margins by integrating
planning, scheduling objectives and economics with actual operations in
a closed loop. Aspen GDOT optimizes broad envelopes of refineries like
the middle distillate system, naphtha processing, residue processing and
H2 networks by coordinating several APC controllers for multiple process
units in real time. The patented data reconciliation technology
available in Aspen GDOT keeps models aligned with the actual performance
of units.
