基于能量集成的CO_2减排量的确定

CO_2 emission reduction through energy integration

能源活动引起的排放占CO2排放量的绝大多数。因此,对企业的能量系统进行集成,不仅可以提高能源的利用效率,也可以减少CO2的排放。本文给出了由于节能所引起的CO2减排量的计算方法,并以某石化公司对苯二甲酸装置的能量集成项目为工程实例,计算出能量集成形成的CO2减排量。计算结果表明能量集成对CO2减排有显著的作用。

The CO2 emissions are mostly from energy utilization. Energy integration not only improves energy utilization efficiency, but also reduces CO2 emission. This paper introduces a calculation method for the reduction capacity of CO2 emission through saving energy. In this paper, a case study based on a project of energy integration on a purified terephthalic acid （PTA） plant is presented. The results of the case study indicate that energy integration has significant effect on CO2 emission reduction.
