AspenTech Software and Services Implementation Also Helps Korea’s Largest Chemical Company Achieve Operational Excellence Goals

BURLINGTON, Mass. – January 5, 2010

Aspen Technology, Inc. (OTC: AZPN.PK) today announced that LG Chem’s deployment of aspenONE Advanced Process Control has resulted in $4 million of annual operational savings, while also helping the chemical
company achieve its operational excellence goals.

In a single plant – the Daesan ethylene facility – the AspenTech Services team’s implementation of aspenONE APC delivered a 2 percent increase in ethylene and propylene production, and reduced total NCC energy consumption 1.5 percent while meeting plant constraints.

LG Chem also realized operational excellence goals with reduced loss of ethylene and propylene, and more stabilized operations compared to previous issues of frequent flooding and product off-specifications.

As a result of the initial project’s success, AspenTech is implementing a Real Time Optimization (RTO) project to further improve operational excellence at LG Chem.
