The project comprises three main phases. The first deals with the data gathering from desalting units all over the country, in either case of operational or design situations. Based on the observed and determined deviations between those situations regarding the energy consumption, 12 desalting units is supposed to be selected in the 2nd phase to be studied concerning the energy audit, utilizing the analytical tools of exergy analysis and pinch hypothesis. Some advices, thereafter, are to be proposed for the selected units while the energy and exergy analysis would prove the energy and exergy efficiencies. Furthermore, compilation of a set of standards for energy consumption in desalting units, together with the preparation of some educational notebooks is the main obligations for the 3rd phase. Project was finished in February 2015.
