Process for controlling the energy performance of an industrial unit, in which process: the value of a set (V) of variables relating to the industrial unit and to the environment are measured, as is the value of a quantity representing the energy performance (W), an estimate (W) of the quantity representing the energy performance is calculated, the value of an energy performance indicator (TE, TE) is determined and the value of this indicator is compared with at least one threshold value (S) determined so as to detect a drift in the energy performance. The invention proposes the learning of a model based on the best energy performance (W) observed for each value of a set (V) of input variables and in the proposing in real time to the operator of a best configuration and of best settings (CR) of the equipment based on those associated with this best energy performance (W) observed in the past for the current value of the set (V) of input variables.

Process for controlling the energy performance of an industrial unit

Method of tracking the performance of an industrial appliance (E), in which an estimate (W) of the quantity representing the electrical power consumed is calculated, in real-time, using the model (M), based on the values of the set (F) of operating parameters of the industrial appliance (E), the difference between the measured value (W) of the electrical power consumed (W) and the estimated value (W) provided by the model (M) is calculated, to obtain the overconsumption value, based on a statistical test on the overconsumption variable, using the distribution of this variable, an overconsumption score is deduced from this corresponding to a probability of overconsumption (p) and an alarm is triggered if the probability of overconsumption (p) exceeds a given overconsumption probability threshold (s), so constituting an overconsumption indicator.

Method of tracking the performance of an industrial appliance

The invention relates to a method of adjusting a unit that is used to control an installation for the adsorption treatment of a gas, comprising: at least a first member and a second member (, R, . . . , R) which receive a gas; a connection conduit () which connects the first and second members to one another; and a valve on the connection conduit, which is closed and opened selectively in accordance with a variable valve-opening parameter. The control unit controls the opening of the valve according to the opening parameter on the basis of: an earlier opening parameter for the valve, a provisional valve opening parameter and at least one correction parameter. The inventive method comprises a step (a) in which the correction parameter is adjusted as a function of the installation and flow parameters.

Method of adjusting an installation for the adsorption treatment of a gas

A method and an apparatus for automatically monitoring the performance of industrial equipment during its operation. During this monitoring, various operating parameters of the equipment are measured, a performance factor representative of the equipments operation is calculated, and information is indicated to a user as a function of the performance factor. Automatic calibration of the performance factor calculation may be performed at the request of a user.
