炼油过程碳排放量化模型构建及汽油质量升级碳排放测算

采用作业成本法将各装置生产过程中的能耗折合成碳排放量，分配到该装置的产品中，成为产品携带的碳排放，逐级向下游装置传递，并建立便于推广应用的传递计算模型，可用于准确计算各中间组分、各产品的碳排放量。作为模型应用实例，测算了汽油质量升级对炼油生产过程碳排放的影响。随着质量升级，炼油厂总碳排放增加，高标号汽油碳排放显著提升。综合考虑汽油生产和使用环节，低标号乙醇汽油碳排放减少，但高标号乙醇汽油碳排放增加。

MODELING OF CARBON EMISSION IN REFINING PROCESS AND ESTIMATION OF CARBON EMISSION FROM GASOLINE QUALITY UPGRADING

The energy consumption in the production process of each unit was converted into carbon emission by activity-based costing method, and then distributed to the products of the unit as the carbon emission carried by the products, and transmitted to the downstream unit step by step. The transfer calculation model was established to calculate the carbon emission of each intermediate component and each product accurately. As an application example, the effect of gasoline quality upgrading on the carbon emission of refining process was calculated. With the quality upgrading, the total carbon emission increased, and the carbon emission of high-grade gasoline increased significantly. Considering the production and use of gasoline, the carbon emission from low-grade ethanol gasoline was reduced, but that from high-grade ethanol gasoline was increased.
