The general ways of improvement the primary petroleum refining rigs have been described in this article. It has been proposed to consider the operational control of primary petroleum refining processes as the most perspective branch of petroleum industry due to its comparatively cheap implementation. Operational control has a significant influence on the safe operation of equipment, products quality and amount of harmful emissions. Electrical conductivity and relative permittivity have been defined as the specific parameters for effective operational control.Primary oil refining rigs are the most important part of any petroleum refinery. Despite the Nelson complexity index which is only 1,0 for refineries it should be considered that they have a strong impact on the secondary refining rigs. That’s why one of the most important task in the petroleum refining industry worldwide is improvement of primary oil refining rigs.
