Abstract:
1. A method for adjusting a control unit of an installation for treating gases by adsorption, said installation being suitable for implementing a method for producing gas during which a feed gas laden with impurities is supplied to the installation, for producing at least one gas issuing from the purification of the feed gas, said production method comprising a plurality of steps, during which a gas is subjected to a flow in said installation, said flow having a number of characteristic flow parameters, said installation comprising a plurality of members: said installation further comprising: a system being defined by two members connected together by a connecting line equipped with a valve, said installation having a number of characteristic installation parameters, and said control unit being suitable for calculating, for each system, a forecasting parameter for opening the valve, a setpoint for said physical flow parameter, an error between a function of said setpoint and the function of said measured value, said control unit being suitable for ordering the opening of the valve according to said opening parameter for each system, for each step, on the basis of at least said forecasting parameter for opening the valve, and at least one correction parameter applied to said error, said adjustment method comprising a step (a) in which said correction parameter is adjusted according to said characteristic installation and flow parameters.
