| dc.description.abstract | The aim of this thesis is to develop a simulator for a combined separation system of oil in water with control purposes. It is part of the research program SUBPRO where two separation units that have been built independently will be merged into one separation system. The main research purposes of theses experimental units is to study sub sea processing of oil and gas extracted in order to move the stream processing to the seabed instead of the usual topside processes. The simulator discussed in this thesis is for both units placed in series, it is the followup of the work done in a specialization project where a simulator for the first unit had been developed, time dynamics has been added and it has been merged with the simulator of the second unit. The model developed for the first unit has also been evaluated with respect to experimental data. Furthermore an optimal control structure has been implemented with promising results, nevertheless issues concerning the time dynamics have been encountered that might be solved using more a more advanced control structure. | |
