摘要
原油混输调度是炼油厂调度的源头,对生产起重要作用。针对由油轮、泊位、码头罐、管线、厂区罐和蒸馏装置组成的原油混输系统,考虑码头罐单储、蒸馏装置进料质量要求等实际操作因素,建立基于异步时间段表征的原油混输调度模型。以国内某典型沿海炼油厂为例,对模型求解方案的可行性和求解效率进行验证。结果表明,虽然模型规模较大,但模型能在较短求解时间内获得全局最优解,相应调度方案中码头罐和厂区罐收付油操作合理,充分缩短了滞船期和卸油时间,可保证蒸馏装置平稳运行,实现卡边操作。所建原油混输模型具有较好的工业应用价值。
Scheduling of crude oil operations is the first step of the refinery operations, which decides the subsequence process management. Based on the information of vessels, berths, terminal storage tanks, pipelines, factory tanks and crude distillation units of the refinery system and the consid- eration of the actual operation, like terminal tanks of single store, the feed quality requirements for the distillation units, et al, a blended crude transportation scheduling model was established based on asynchronous time characterization. Taking a typical domestic coastal oil refinery as an example, the feasibility of the model and solution efficiency was validated. The proposed model can obtain the optimal scheme in a short time despite the large scale of the model, which ensures the reasonable operations of terminal storage tanks, pipelines, factory tanks, fully shorten the delay shipping date and unloading time, and satisfies the requirements for smooth running of the crude distillation units, and realizes criti- cal operation. The practical values of this scheduling model are worthy of being appreciated.
