Abstract: A method of detecting E-line loss in a disc stack centrifuge is provided, comprising: collecting data from at least one instrument associated with the centrifuge over a specific time period; calculating one or more indicators by comparing the collected data with expected values from a normally operating centrifuge, the indicators being indicative of a start of an E-line loss event; calculating the probability of E-line loss by applying weighted voting to the indicators to yield a probability value; and activating an alert upon determination that the probability value exceeds a threshold value.

Abstract: A computer-implemented method and a system for optimizing diluent recovery of a diluent recovery unit (DRU) used to recover a diluent from a tailings generated by a bitumen froth treatment process (BFTP). A regression model is determined from data points for operating conditions and corresponding diluent recovery, generated during operation of the DRU. The regression model is used to predict diluent recovery under a particular operating condition and determine a recommended value of the operating condition to achieve a target diluent recovery. The system may graphically display the regression model, the predicted diluent recovery and the recommended value, or cause the DRU to vary the operating conditions towards the recommended value.
