摘要
针对中国石油化工股份有限公司洛阳分公司第Ⅱ套重油催化裂化装置主分馏塔出现的在塔顶冷回流用量和顶循环流量都很大的情况下塔顶产品粗汽油干点高、质量不容易控制、顶循环抽出温度低、低温热利用率低等问题,利用AspenPlus流程模拟软件对主分馏塔进行模拟计算,找出存在问题的原因,提出优化和改造方案,实施后主分馏塔的操作弹性增加,产品质量容易控制。
Problems, such as unstable product quality, high end point of naphtha, low outlet temperature of top pump-around reflux and poor utilization of low temperature heat, occurred at the main fractionator of the RFCCU II of SINOPEC Luoyang Company. A process simulation model of said main fractionator was set up with Aspen Plus software to study the causes of problems and to propose suggestions for troubleshooting and process optimization. After adopting these suggestions, the product quality was easy to be controlled,the operation was more flexible and energy consumption was reduced.
