Abstract [en]

The purpose of this paper is to discuss how a fundamental mathematical model for prediction of hydrogen and sulphur refining during vacuum degassing can be used to develop on-line process control models. It has first been shown how predictions of sulphur and hydrogen using fundamental mathematical models agree well with measured values from plant trials. These models and analytical equations have thereafter been used to predict hydrogen and sulphur refining for new heats. Here, it was shown that these analytical predictions give very similar results as the fundamental predictions. Thus, it is possible to use the analytical equations in production. It is also discussed how the analytical process models can be used both as on-line or off-line tools in industry.
