• Majority of applications (67%) are in refining and petrochemicals. Chemical and pulp and paper are the next areas. • Many vendors specializing in the technology – Early Players: DMCC, Setpoint, Profimatics – Today’s Players: Aspen Technology, Honeywell, Invensys, ABB • Models used are predominantly empirical models developed
