摘要： A control system for a continuous liquid phase hydroprocessing reactor having an upper zone of gases and a substantially larger lower zone of liquids surrounding a catalyst, comprising: (a) an indicator located on said reactor, (b) means for sensing the quantity of liquid in said reactor; (c) an indicator reading obtained from said sensing means; (d) means for converting said indicator reading to an indicator signal; (e) a computer to receive said indicator signal; (f) means for transmitting the indicator signal to said computer; (g) a software program to interpret said indicator signal and make adjustments based on said indicator signal; (h) means for converting said adjustments to an adjustment signal; (i) means for transmitting said adjustment signal; (j) a hydrogen control valve, located upstream from said reactor, which adjusts the amount of hydrogen going into a reactor feed; (k) means for interpreting the adjustment signal at said hydrogen control valve; and (l) means for adjusting said hydrogen control valve based on said interpreting means.

摘要： A continuous liquid phase hydroprocessing process, apparatus and process control systems, where the need to circulate hydrogen gas through the catalyst is eliminated. By mixing and/or flashing the hydrogen and the oil to be treated in the presence of a solvent or diluent in which the hydrogen solubility is high relative to the oil feed, all of the hydrogen required in the hydroprocessing reactions may be available in solution. The oil/diluent/hydrogen solution can then be fed to a plug flow reactor packed with catalyst where the oil and hydrogen react. No additional hydrogen is required; therefore, the large trickle bed reactors can be replaced by much smaller tubular reactors. The amount of hydrogen added to the reactor can be used to control the liquid level in the reactor or the pressure in the reactor.
