Abstract:
The 1989 developed LP model on the refining industry in the Netherlands(SERUM) is used for long term energy scenario's developed at ECN. It is able to calculate the effect of various changes in crudes, feedstocks, product demand, product specification, energy use and SO2-emission standards. The model contains three different refineries which equally fulfill product demand. Each refinery has its own processing units, energy supply and blending facilities. This report describes a set of calculations using the model to illustrate its main features. In the model, and in practice, energy consumption is mainly influenced by throughput and product mix (percentage of heavy products). According to the model there is an optimal balance in the ratio between diesel and gas oil on one hand and both naphtha and gasoline on the other hand. A product ratio, which differs from the balance value, can cause an increase of 10% in energy consumption or meet with production limits. The model contains no separate energy saving measures. Difference between model and practice can be observed in the amount of natural gas firing and the handling of heavy fuel oil. It appears that not all practical restrictions are incorporated in the model. The model is able to calculate the effect of certain changes in product quality or SO2-emission limits. Cost and energy figures of these changes are comparable with literature values. 1 fig., 23 tabs., 6 refs.
