  • Method of and apparatus for controlling rate of material air supply to air separation plant
    Patent number: 4261719
    Abstract: A method of and apparatus for optimizing the rate of material air supply to an air separation plant, for preserving a stable operation of the plant, through stabilizing heat balance and material balance in the plant irrespective of variation in the flow rate of a gas through an expansion turbine incorporated in the plant and the flow rate of product gases so as to optimize the purity and amount of produced gas. The control for the optimization is performed making a ratio of the difference between the flow rate of the material air and the flow rate of the gas through the expansion turbine to the flow rate of the product gases, as an essential factor for the control.
