Leading producer of acrylic products to use AspenTech's economic evaluation tools to help identify optimal process designs and to make better investment decisions

CAMBRIDGE, Mass., Sep 8, 2003 (BUSINESS WIRE) -- Aspen Technology, Inc. (Nasdaq: AZPN) today announced that Mitsubishi Rayon Co., Ltd, a leading producer of acrylic products, is expanding its use of Aspen Engineering Suite (AES)(TM) solutions with a new multi-year license agreement. Under the terms of the agreement, Mitsubishi Rayon is adopting AspenTech's tools for economic evaluation to help identify optimal process designs and to make better capital investment decisions.

Mitsubishi Rayon will use the economic evaluation solutions, based on Aspen Icarus Process Evaluator(TM), to provide accurate estimates of the capital investment and operational costs associated with new or updated manufacturing processes. According to the company, the solution could shorten process cost estimation time from one month to one day, enabling its process engineers to study a much greater number of alternatives processes, and to select the process design with the lowest overall lifecycle costs.

"AspenTech's process simulation and optimization solutions are established as a clear technology leader in the chemicals industry," said Mr. Tajiri, Director of Mitsubishi Rayon. "Over the past nine years, Mitsubishi Rayon has realized significant benefits from using the Aspen Engineering Suite as a standard tool within our process development group. This new agreement will enable our process engineers to generate even greater value using a broader range of AES technologies."

Mitsubishi Rayon has used AspenTech's engineering solutions since 1994, and has used AES simulation and optimization technologies to improve the quality and efficiency of its manufacturing processes producing a range of chemicals and plastics, fibers and high-performance materials. In addition to optimizing existing processes, the company has also applied AES tools to support new process start-ups such as its methyl methacrylate (MMA) plant in Thailand and for new facilities under construction in China.

"Making the right process design and investment decisions is critical for process manufacturers," said David McQuillin, President and CEO of AspenTech. "AspenTech's economic evaluation solutions allow process engineers to develop full conceptual cost estimates quickly and accurately. This enables companies to achieve significant cost savings by ensuring the design they select provides the greatest returns on their capital investment."
