In the second place, based on the asu of buggenum igcc plant in netherlands, both static and dynamical model for distillation tower of the asu are created and some valuable conclusions are gained as well. finally, a compartmental simplified model is created for distillation tower of the asu, in order to reduce the simulation time and increase the simulation efficiency. the new model will be helpful to the further simulation and on - line optimal control for the asu of the igcc plant

餾塔的半圖形化
動、靜態數學模型,並通過模擬,得出了一些有價值的結論:當空分系統的壓力變化時,氧氣產品濃度的響應時間常數為兩小時左右,說明空分系統是igcc電站最大延遲環節;而且雖然氧氣濃度最後會穩定在igcc電站所要求的范圍之內,但在過渡過程中會超出限制,這些都為igcc電站的安全運行及控制系統設計提供了有價值的信息。

Through analyzing the effect of temperature and nitrogen on crude oil viscosity the influences of different nitrogen injection volume and injection modes on steam displacement are contrasted, the mechanism of nitrogen - assisted steam stimulation is clarified, which includes : heat carrying capacity is raised, the saturation of remaining oil is reduced after nitrogen - assisted injection is made ; crude oil flow is enhanced because of nitrogen compression and dispersion and the change of oil flow shape ; water back - production rate is improved by expanding the steam sweep volume and compensating in - situ energy ; steam distillation effect is enhanced
通過分析溫度、氮氣對原油粘度的影響,對比不同注氮量、不同注入方式等對蒸汽驅油效果的影響,弄清了氮氣輔助蒸汽增產的機理主要表現在:氮氣輔助后增加攜熱能力,降低殘余油飽和度,氮氣的壓縮膨脹作用分散和改變了原油流
