合成气净化单元能耗计算方法

为了对某煤制烯烃全厂能量系统进行优化研究,提出基于单元、子系统和全局分段递进协同优化的策略,首先对全厂各个单元进行能耗计算和节能分析。在对合成气净化单元进行能耗分析和计算时,发现目前合成气净化单元粗合成气中夹带水蒸气的折标系数没有统一的基准,因此对合成气净化单元能耗计算方法进行了探索研究,提出了合成气净化单元能耗计算方法,规定了粗合成气中夹带水蒸气的折标系数选取方法以及单位能耗计算的基准。结果表明:提出的方法能较好地反映合成气净化单元的能效水平,并为合成气净化单元对标分析提供统一计算基准,为合成气净化单元能耗计算标准制定提供参考。

Calculation method of energy consumption in synthesis gas purification unit

In order to optimize the energy system of a coal to olefin plant,a segmented progressive and collaborative optimization strategy was proposed based on unit,subsystem and globally.It was found that the standard coal coefficient of water vapor in crude synthesis gas was no unified benchmark with the synthesis gas purification unit energy consumption analysis and calculation.Thus the calculation method of unit energy consumption in synthesis gas purification unit was studied.The calculation method of energy consumption in synthesis gas purification unit was proposed.The method provided how to select the standard coal coefficient of water vapor in the crude synthesis gas and the calculation base of unit energy consumption.It provides a standard calculation for benchmarking analysis of synthesis gas purification unit and provides reference for the calculation standard draft of energy consumption of synthetic gas purification unit.
