Experts, Executives and Users in Dialogue    The congress programme, consisting of 925 lectures attended by some 27,000 visitors, is the second cornerstone of ACHEMA next to the exhibition itself. Numerous special and guest events, podium discussions, expert talks and plenary lectures provide a multi-faceted, highly topical and high level congress programme reflecting the great diversity of process engineering. Podium discussions with leading personalities from the fields of science, business and politics as well as many guest events, among others those organised by the International Association for Social Security (IVSS), the VDI-GVC Association for Process and Chemical Engineering and the GDCh Association of German Chemists, will round off the ACHEMA 2009 lecture programme. Focus on Automation Technology: NAMUR Experts’ Round Tables After its successful debut in 2006, the round table sessions organised by NAMUR (International User Association of Automation Technology in Process Industries) addressing topical issues in instrumentation, control and automation techniques will again be a focal point at ACHEMA 2009, which emphasises the NAMUR acknowledgement of the ACHEMA as a leading event in this field. The paper submission is closed. Additional papers may only be accepted if free lecture time are available.
