    Abstract: In a distillation control system, a nuclear magnetic resonance (NMR) sensor identifies the composition of petroleum distillates from a distillation tower, and preferably also identifies the composition of the input feed method. This information is processed to obtain estimates of values of selected properties of the distillates and the feed. These values are provided to a multivariate controller, together with a setpoint of desired quality factors selected on the basis of competitive market forces, environmental regulations and economic factors including feed and product prices and operating cost. On the basis of the NMR measured values of selected quality properties, the multivariate controller generates values of manipulated operating variables that, when applied to the distillation system, adjust the distillation operation to reduce differences between the controlled variables and their respective setpoints. The ultimate values of the operating variables are determined, preferably in conjunction with an optimizer so that product qualities are maintained and the tower is operated in an economically optimum manner subject to specific characteristics of the refinery.

    Abstract: A novel reaction vessel apparatus (110) is provided. The reaction vessel (110) includes internally placed temperature controlling thermal probes (400) in which liquid is boiled. The energy of vaporization is supplied by the reaction vessel contents. The vapor produced by the boiling may be directed to channel coils (100) which surround the outside of the reaction vessel wall (120). The channel coils (100) contact the outside wall (120) of the reaction vessel (110) perpendicularly, and provide mechanical support for the reaction vessel. The mechanical support from the channel coils (100) allows for a decrease in the thickness of the reaction vessel wall (120) and corresponding increased heat transfer efficiency between the channel coil contents and the reaction vessel contents. The entire above described apparatus is enclosed within an evacuated shell (300) which provides additional insulation.

    Abstract: A tube heat exchanger intended to be used for the production of carbon black, comprises a cylindrical chamber (16) which is enclosed by a cylindrically shaped outer shell wall (14') and two end walls (17, 18), and a plurality of tubes (13') which extend through the entire cylindrically shaped chamber (16), from one end wall to the other. To the heat exchanger are provided an inlet (1') and an outlet (25) for gas intended to flow on the outside of the tubes (13'). Moreover, the heat exchanger comprises a further shell wall (23), which is cylindrical and placed inside and concentrically with the outer shell wall (14'), so that a cylindrically shaped gap space (29), which is open at both ends, is formed between the two shell walls. The gas entering through the inlet (1') passes this gap space (29) before it comes into contact with the tubes (13'). The advantage of this is that the outer shell wall is cooled and that the amount of carbon precipitations within the tubes diminishes.

    Abstract: A method for controlling a process for synthesising at least one chemical in a plant including at least one reactor (R) that may be considered as a perfectly mixed reactor, wherein control variables (GC) enable the process to be controlled so that a number of variables known as controlled variables (GR) and related to the properties of the product and/or the operation of the process match corresponding set values (CGR). Said method comprises the steps of (a) inputting set values for the controlled variables (CGR); (b) using a prediction unit (OP) to calculate predictions of the controlled variables (PGR) on the basis of measurements of the process control variables (MGC); (c) using a control unit (OC) to calculate set values for the process control variables (CGC) on the basis of the set values (CGR) and predictions (PGR) of the controlled variables; and (d) transmitting set values for the process control variables (CGC) to process control actuators. The prediction unit (OP) is based on a mathematical process model known as a direct model (M), and designed in such a way that the mass MXR of at least one component (X) in the reactor (R) is predicted by means of the equation MXR = LAG (FXRin . tau X, tau X), wherein FXRin is the mass flow rate of component X at the inlet of the reactor R, tau X is the dwell time of x in the reactor, and the function y = LAG (u, tau ) is the solution of the differential equation tau . dy/dt + y, calculated with the instantaneous value of u and tau as well as with the last calculated value of y.
