Abstract
A method for obtaining an air product in an air separating system in which a liquid fraction is obtained from feed air and used to provide the air product and in which the liquid fraction is temporarily stored in a tank arrangement. A tank arrangement with at least two tanks is used, and the liquid fraction is fed to at least one of the tanks and/or is removed from at least one of the tanks in order to provide the air product. In the process, the liquid fraction is not fed to and removed from any one of the tanks at the same time, and the composition of the liquid fraction in a tank is ascertained prior to each removal of the liquid fraction from the tank. An air separating system is also described.

A method for obtaining an air product in an air separating plant, said method comprising:
- obtaining a liquid fraction from feed air and said liquid fraction is used at least in part for providing said air product,
- introducing said liquid fraction is into a tank arrangement having at least two tanks,
- wherein said liquid fraction is fed to one or more of said tanks of the tank arrangement and is withdrawn from one or more of said tanks of the tank arrangement to provide said air product and said liquid fraction is not simultaneously fed to and withdrawn from any of said tanks, and
- wherein, prior to withdrawing liquid fraction from said one of the tanks, the composition of the liquid fraction within said one of the tanks is determined.
An air separating plant comprising:
- a separation system for obtaining a liquid fraction from feed air, and said separation system having a discharge system wherein at least part of the liquid fraction is used to provide an air product,
- said discharge system comprising a tank arrangement with at least two tanks set up to store the liquid fraction, and means for feeding the liquid fraction to at least one of the tanks and means for withdrawing the liquid fraction from one or more of the tanks to provide the air product and said means for feeding and said means for withdrawing cannot simultaneously feed and withdraw the liquid fraction from any of the tanks of the tank arrangement, and, and
- a control device for determining the composition of the liquid fraction prior to the liquid fraction being withdrawn from a tank of the tank arrangement to provide the air product.
