Abstract

Exergy pinch-analysis of the heat exchange system of the furnace of the primary oil refining unit is carried out. Composite curves are created using a mathematical model, and then the optimal structure of the heat exchange with minimal exergy losses is constructed. Exergy pinch analysis allows revealing the magnitude and location of exergy losses. In the heat exchange system of the furnace exergy loss is 9 MW. It is possible to increase the efficiency of the furnace by 18.5%. An additional heat exchanger connecting it to the oil stream is introduced for rational use of residual exergy.

利用夹点分析技术对炼油工艺的能源效率进行评价

对一次炼油装置加热炉换热系统进行了火用压缩分析。利用数学模型建立复合曲线，构造出以最小火用损失为代价的最优换热结构。火用夹点分析可以揭示火用损失的大小和位置。在换热系统中，该炉的火用损失为9mw。有可能使炉的效率提高18.5%。为了合理利用剩余的火用，引入了一个附加的热交换器将其连接到油流。
