Method for operating a production plant of modular design

A production plant for producing a chemical and/or pharmaceutical product, the production plant comprising:

• at least two transportable process modules (P1 . . . Pn),
• at least one reversible connection between each of the at least two process modules (P1 . . . Pn),
• wherein each said at least two process modules (P1 . . . Pn) includes at least one respective electronic device (E1 . . . En),
• wherein each said at least two process modules (P1 . . . Pn) further includes at least one material quantity sensor detecting the filling level of the material in the respective at least two process module (P1 . . . Pn) and connected for communication purposes to the at least one electronic device (E1 . . . En) of the respective at least two process modules (P1 . . . Pn), and,
• at least one electronically activated flow valve positioned between each of the at least two process modules (P1 . . . Pn),
• wherein each said electronic device (E1 . . . En) is a control and/or regulating device configured to detect an amount of material that is respectively present in one or more of the respective at least two process modules (P1 . . . Pn) and to be processed by the one or more modules (P1 . . . Pn) to compare the amount of material with a prescribed limit value for the amount of material and,
• wherein each electronic device (E1 . . . En) is additionally configured to actuate the at least one electronically activated control valve to initiate a flow of the material into or out of the respective at least two process modules (P1 . . . Pn) to increase or decrease a mass flow between the respective at least two process modules (P1 . . . Pn) and an adjacent process module (P1 . . . Pn) of the at least two process modules (P1 . . . Pn)
• wherein if the amount of material that is respectively present in the respective process module (P1 . . . Pn) and is to be processed by the respective process module (P1 . . . Pn) is less than the limit value for the amount as detected by the fill sensor, an inflow into the respective process module (P1 . . . Pn) is at the same time an outflow of a further at least two process module (P1 . . . Pn) connected directly upstream of the respective process module (P1 . . . Pn) for production purposes, and,
• wherein if the amount of material that is respectively present in the respective process module (P1 . . . Pn) and is to be processed by the respective process module (P1 . . . Pn) is greater than the limit value for the amount as detected by the fill sensor, to actuate an outflow out of the respective at least two process module (P1 . . . Pn) the outflow at the same time being an inflow of a further process module (P1 . . . Pn) connected directly downstream of this process module for production purposes.
