Abstract

A system and method for controlling the solvent refining of a charge oil to obtain refined waxy oil of a specific quality which is subsequently dewaxed to provide refined oil. During a predetermined time period, the characteristics of the charge oil are sensed and corresponding signals provided. After the predetermined time period, characteristics of the charge oil, the refined waxy oil, extract oil and solvent are sensed and corresponding signals provided. Analog computers provide signals in accordance with equations, hereinafter disclosed, for controlling the charge oil flow rate and the temperature of the extract-mix in accordance with the condition signals and other signals corresponding to the current economic values of the charge oil, the refined oil and the extract oil.
