摘要
通过对国内现有连续重整装置设计能耗的分析,比较连续重整装置各单元的能耗分布及采用不同连续重整专利技术对装置能耗的影响,并对其生产成本进行了简要分析。连续重整装置的主要能耗在于原料预处理和重整反应及产物分离部分的燃料消耗,催化剂再生部分的能耗占总能耗的比例较小。若原料性质、产品方案、装置规模相同,采用不同专利技术的连续重整装置,其能耗差别主要在于催化剂再生部分。采用冷循环催化剂再生流程的能耗指标和生产成本高于热循环再生流程,其中以用电的消耗差别较大,但从总体而言,催化剂再生部分的能耗差别对整个装置的能耗影响不大。
This article analyzed the energy consumption within the continuous catalytic reforming unit（CURE）and discussed the effect of the catalyst regeneration technology on the energy consumption and overall capital cost. It was found that in the CURE, the heating requirement for feed pretreatment,reforming reaction and product separation had more energy consumption than other parts of the system. When comparing the energy consumption of CURE using different catalyst regeneration technologies designed for similar feedstock composion, products and capacity, the difference mainly resulted from the catalyst regeneration section. Process with hot circulation had an edge in energy saving than that of process with cold circulation. However, the energy consumption from this section had little impact to the overall energy consumption of the CURE.
