    摘要： A solvent refining unit treats medium sour charge oil with an N-methyl-2-pyrrolidone solvent, hereafter referred to as MP, in an extractor to yield raffinate and extract mix. The MP is recovered from the and from the extract mix and returned to the refining extractor. A system controlling the refining unit includes a gravity analyzer, a sulfur analyzer, a refractometer and viscosity analyzers; all analyzing the medium sour charge oil and providing corresponding signals, sensors sense the flow rates of the charge oil and the MP flowing into the extractor and the temperature of the extract mix and provide corresponding signals. One of the flow rates of the medium sour charge oil and the MP flow rates is controlled in accordance with the signals from all the analyzers, the refractometer and all the sensors, while the other flow rate of the medium sour charge oil and the MP flow rates is constant.

    摘要： A system controls a furfural refining unit in which the furfural refining unit includes an extractor receiving furfural and charge oil, one of which is at a predetermined flow rate while the other flow rate is to be controlled and providing raffinate and extract mix. The control system includes sensors sensing the flow rate, the gravity, the viscosity, the flash point temperature, the refractive index and the sulfur content of the charge oil. Other sensors sense the flow rate of the furfural and the temperature of the extract mix. The signals from the sensors are provided to control apparatus which controls the other flow rate of the charge oil and the furfural flow rates in accordance with the signals from the sensors.

    摘要： A solvent refining unit is controlled so that it has a maximum allowable solvent flow rate or a maximum allowable extract oil flow rate. The temperature of the extract-mix in the refining tower, the flow rate of the charge oil, the flow rate of the solvent and the flow rate of the extract oil are sensed by sensors which provide corresponding signals. A circuit provides signals corresponding to desired flow rates for the charge oil and the solvent and for a desired temperature for the extract-mix in the refining tower. The refining unit is operated in accordance with the desired signals so as to achieve either a maximum allowable flow rate for the solvent or a maximum allowable flow rate for the extract oil, or a maximum allowable flow rate for the refined oil, or a reduced charge oil flow rate for a fixed refined oil flow rate.

    摘要： A system for controlling a solvent refining unit so as to operate the refining unit at the maximum limit of its operating parameters. Three such operating parameters are the refining temperature which is limited by the miscibility of charge oil and the solvent, the flow rates of extract oil and refined oil, which are limited by the mechanical design of the refining unit, obtained from the refining of the charge oil. A plurality of computers determine the values of constants from equations, hereinafter disclosed, so that the operating parameter that is limiting may be determined. A plurality of analog computers generate control signals for the different limiting operating parameters. Switching means apply the proper control signals to the refining unit in accordance with the determination of which operating parameter is limiting.
