Improved Process Control Helps Leading Eastern European Petrochemical Company Realize Greater-Than-Expected Benefits

Aspen Technology, Inc., (Nasdaq: AZPN) today announced it has enabled Chemopetrol, a leading petrochemical company in Eastern Europe, to realize significant economic benefits from the implementation of a production optimization solution. Just six months after completion of the project, Chemopetrol has already increased its ethylene production by 2.5 percent, resulting in a significant increase in revenues for the company.

Chemopetrol implemented the solution at its plant in Litvinov, which is part of the Czech Republic, to meet increasing customer demand for ethylene products. Advanced process control and information management technology from AspenTech enabled Chemopetrol to operate the plant closer to its optimum conditions, resulting in increased output, as well as safer operations. The implementation has also reduced the burden on the operators of routine monitoring of plant constraints and changes of plant feed targets, allowing them to focus on higher-level plant operation activities.

The project focused on improving processes on the olefins unit, thereby optimizing the front-end process train, including the furnaces and compressor area. Key benefits for Chemopetrol include optimum utilization of its existing manufacturing assets and a better ability to make more profitable operating decisions. AspenTech's technology will also support Chemopetrol's plans to gain increased returns in the future as it expands its plant operations to include polymer production.

"This project is part of Chemopetrol's continued strategy to improve plant efficiency and, through increased production, enhance its position in a very competitive Eastern European marketplace," explains Vladimir Zemanek, Investment Director of Chemopetrol. "AspenTech's expertise in state-of-the-art solutions for ethylene units was key when we chose a supplier, and the immediate improvement in plant performance has made us less dependent on expensive feedstock purchases for our downstream production units."

"Production optimization technology can generate significant value for chemical manufacturers through increased throughput and improved responsiveness," says Larry Evans, Chairman and CEO of AspenTech. "The substantial increase in production capacity achieved by Chemopetrol demonstrates the outstanding return on investment that is possible by applying AspenTech's manufacturing solutions."
