摘要： Provided are a device and method for predicting product properties of a naphtha splitting unit (NSU). The method includes training a prediction model for predicting the product properties of the NSU, inputting an input variable to the trained prediction model to acquire a prediction value for each output variable, and outputting the acquired prediction values for the output variables.

摘要： Disclosed are a method and apparatus for controlling a reactor in a reformer. According to an embodiment, a method of controlling a reactor in a reformer includes training a first prediction model for predicting properties of feed in a reformer and a second prediction model for predicting properties of products in the reformer; predicting the properties of feed being currently supplied to a reactor set in real time by allowing a first prediction unit including the trained first prediction model to receive a current operating condition of the reactor set in the reformer; predicting the properties of products being produced in the reactor set in real time by allowing a second prediction unit including the trained second prediction model to receive the current operating condition and the predicted properties of feed; calculating a amount of temperature fluctuation to be applied to each reactor as a control signal for controlling each of the reactors of the reactor set based on the predicted properties of products; and controlling an operating temperature of each of the reactors based on the calculated amount of temperature fluctuation.
