A study of flow interruptions in the HYL III reactor

Since January 1994, PT Krakatau Steel has been operating a new Direct Reduction plant with the Hyl HI process, a continuous moving bed reactor. During the operation, some problems emerged regarding flow interruptions at the outlet of reactor. It is quite difficult to observe the reason why the flow interruption occurs in actual operation because it requires considerable cost and will certainly disturb the production. Therefore, developing and implementing a model (one tenth of the actual size) representing the actual reactor is a method to simplify the observation.
