A method for obtaining one or more air products, wherein an air separation system having a rectification column system is used, in which pressurized air is processed in an adjustable total air volume, wherein the total air volume is set to a first value during a first operating period and set to a second value that is different from the first value during a second operating period, and wherein the setting of the total air volume is changed from the first value to the second value in a third operating period from a first time to a second time. The second operating period is after the first operating period, the third operating period is between the first operating period and the second operating period. In the third operating period, a setting of a volume of a fluid, is changed from a third time up to a fourth time.
A method for obtaining one or more air products, wherein an air separation system having a rectification column system is used in which pressurized air is processed in an adjustable total air volume, wherein the total air volume is set to a first value during a first operating period and set to a second value that is different from the first value during a second operating period, wherein the setting of the total air volume is changed from the first value to the second value in a third operating period from a first time and to a second time, and wherein the second operating period is after the first operating period, and the third operating period is between the first operating period and the second operating period, characterized in that, in the third operating period, a setting of a volume of a fluid, which is formed via rectification using the pressurized air and transported into or out of the rectification column system, is changed from a third time and up to a fourth time, wherein the third time is before or after the first time and before the second time, and the fourth time is after the first time and the third time and before or after the second time, and a time period between the first time and the second time is set to not differ by more than 20% from a time period between the third time and the fourth time.
An air separation system which is configured for obtaining one or more air products and has a rectification column system, wherein the air separation system is configured to process pressurized air in an adjustable total air volume in the rectification column system and to set the total air volume to a first value during a first operating time period and to a second value different from the first value during a second operating time period, and to change the setting of the total air volume from the first value to the second value in a third operating period from a first time and up to a second time, wherein the second operating period is after the first operating period, and the third operating period is between the first operating period and the second operating period, characterized in that the air separation system has a control unit that, in the third operating period, is programmed to change a setting of a volume of a fluid which is formed via rectification using the pressurized air and transported into or out of the rectification column system from a third time and up to a fourth time, wherein the third time is before or after the first time and before the second time, and the fourth time is after the first time and the third time and before or after the second time, and to set a time period between the first time and the second time such that it does not differ by more than 20% from a time period between the third time and the fourth time.
