Modelling of high performance electrocoalescer based on experimental data

Modern approaches to automatic control of crude oil dewatering and desalting are predominantly model-free, described model-based systems lack precise mathematical description. Not a single research provides dynamic input-output model for electric dehydrator, suitable system development. As far as which is the main plant in process, non-linear with distributed parameters, need linearization arises. The aim present study compare different methods obtaining approximate transfer function an dehydrator from graphical experimental data.
