UOP and AspenTech Partner to Market Refinery-Wide Simulation Product

08/04/03

CAMBRIDGE,Mass.--(BUSINESS WIRE)--Aug. 4, 2003--Aspen Technology, Inc. (Nasdaq: AZPN), today announced an agreement with UOP LLC to market Aspen RefSYS(TM), a jointly developed software product for refinery-wide simulation and optimization. The product is based on a combination of AspenTech's refining industry process simulation flowsheet technologies and the best-in-class refinery reactor models developed by UOP and AspenTech.

UOP and AspenTech have had an ongoing relationship delivering leading-edge software solutions to the oil industry. Aspen RefSYS will provide even greater levels of value to refining clients by enabling them to achieve and capture ongoing improvements in the profitability of their refinery operations.

"UOP is excited to partner with AspenTech on this project. Aspen RefSYS offers UOP's clients a software solution that enables them to identify refinery process constraints and improve operational bottlenecks," said Frank Whitsura, Vice President and General Manager of UOP. "Aspen RefSYS will help increase operating margins, support effective capital expenditures, and provide a platform for continuous improvement in our clients' operations."

While traditional modeling solutions can only simulate individual process units, Aspen RefSYS enables companies to optimize refinery-wide performance using an integrated model of their facilities. The combination of flowsheet simulation with accurate kinetic reactor models enables refiners to make improved economic decisions throughout the refinery, from crude feed to final product blending. Additional benefits are derived from leveraging the data generated from Aspen RefSYS to enhance planning and scheduling decisions, leading to increased refinery margins.

"Rigorous refinery-wide modeling enables companies to identify the most profitable operating strategy for the entire refinery," said David McQuillin, President and CEO of AspenTech. "The combination of AspenTech's software technology expertise and UOP's experience in refinery-wide operations will enable us to deliver a unique array of valuable solutions to our refining clients. Our strong relationship with partners such as UOP is key to our success in providing differentiating solutions to the refining industry."
