  • Method of recovering components from coke oven gases using predictive techniques
    Patent number: 5443693
    Abstract: A method for recovering a component from gas that is produced by a coke oven battery. The total amount of gas that will be produced by the coke oven battery is predicted by determining a quantity of coal charged, and determining variations of a production rate of the gas. Therefore, a prediction value of gas to be produced is made based on the quantity of coal and the determined variations. An error is determined between the actually-measured value of gas and a prediction value. The prediction value for that and other times is corrected. Based on this prediction value, gas recovery conditions for the coke oven gas are controlled.
