Patent ID: 7736417

Claim:
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: a feed line conveying a feed gas to be purified by adsorption, a production line conveying a purified gas, a removal line conveying an offgas, containing the impurities of the feed gas, a plurality of cylinders (R 1 , . . . , R 0 ) containing at least one adsorbent material, said installation further comprising: a plurality of connecting lines, each connecting two of said members together, a valve on each of said connecting lines, each valve being suitable for being selectively closed to prevent a flow of gas in the connecting line, or opened according to a variable opening parameter, to allow a flow of gas in the connecting line, 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, suitable for ordering the opening of the valve according to an opening parameter for each system, for each step, for each system, a detection device suitable for measuring a measured value of a physical parameter of the gas flow for the system, 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.
