以某石化公司炼油厂(原油加工能力10.0Mt/a)为例,全厂的低温热源和热阱进行了分析。分析表明,按照“温度对口,梯级利用”的科学用能原则,热源和热阱按照温位高低进行优化组合,在全厂范围内构建低温热大系统,实现能量的综合利用。最终达到节能降耗的目地。 Take a petrochemical company refinery (crude oil processing capacity of 10.0Mt / a), for example, the whole plant of low temperature heat source and heat traps were analyzed. The analysis shows that in accordance with the principle of scientific energy use of “temperature counterparts and cascade utilization”, heat sources and heat traps are optimally combined according to the temperature level to construct a low-temperature thermal large-scale system in the whole plant to realize the comprehensive utilization of energy. Eventually achieve the purpose of energy saving.
