    摘要: The present invention provides method and system for operating reactor units (102) in a process plant. In one embodiment, the process control system (100) comprises a reactor unit (102) provided with an enclosure (104) capable of producing a solute (126) and a residue (130), and automatic control valves (106, 108). The system (100) comprises a first sensor (116) disposed in the enclosure (104) and a second sensor (118) positioned in the discharge pipe (112). The system (100) comprises a control unit (120) which determines formation of a phase (128) between the layer of the solute (126) and the layer of the residue (130) based on process status inputs from the first sensor (116). The control unit (120, 602) operates the automatic control valves (106, 108) based on process status inputs from the second sensor (118) such that the solute (126) and the residue (130) are separately discharged.

    摘要: Devices and methods for determining the cumulative distribution of a polymer property in a reactor without physical separation of reaction subcomponents. The device includes a means of measuring an instantaneous property of the polymers being produced in a reaction vessel a plurality of times during a polymerization reaction as well as a means of determining the corresponding change in polymer concentration in the reaction vessel between measurements of the instantaneous polymer property The device also includes a means of computing a statistical distribution appropriate to the polymer characteristic and applying the statistical distribution to a recently measured instantaneous value of the polymer property so as to have an instantaneous distribution of the polymer property and a means of adding together the instantaneous distributions of the polymer property in order to obtain the cumulative distribution of the polymer property in the reactor.

    摘要: A method is disclosed for controlling retention time in a reactor, such as an autoclave, having a plurality of compartments separated by dividers with underflow openings. A retention time of the reaction mixture is calculated and compared with an optimal retention time, and the volumes of the reaction mixture in the compartments are adjusted while maintaining the flow rate of the reaction mixture, so as to change the retention time to a value which is closer to the optimal retention time. The reactor may include a level sensor in the last compartment for generating volume data; a control valve for controlling the liquid level in the last compartment; and a controller which receives volume data from the level sensor and controls operation of the control valve.
