This paper describes modeling and on-line optimization of a crude unit heat exchanger network at the Statoil Mongstad refinery. The objective is to minimize the energy input in the gas fired heater by optimally distributing the cold crude oil in the heat exchanger network. The steady state mass and energy balance of the 20 heat exchangers in the network(More)
The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data(More)
