Abstract
Fluidized catalytic cracking (FCC) unit has vital role in the process of modern refineries because this unit is used for production of valuable refinery products. The aim of this research is to study different capacities of the feedstock in FCC unit and to find the maximum available capacity with consideration of technical and economic criteria. In this regard, process simulation of this unit is performed in the Aspen HYSYS software. Next, this process simulation is imported to Aspen Capital Cost Estimator (or ICARUS) for operating cost (OPEX) and capital cost (CAPEX) evaluations. Finally, it is tried to optimize the capacity of fluidized bed catalytic cracking process. By investigating the results, it was revealed that the breakeven point (BEP) in this unit is in the capacity of 30 000 barrels per day. It means that total cost (operating and capital costs) and net profit (revenue of products) are equal and at the higher capacities than this BEP, FCC unit has profitability. Based on the economic analysis, it could be found that CAPEX and OPEX in the BEP capacity will be more than 156 618 948 $ and 37 432 199 $/yr, respectively.

通过技术经济分析评价炼油厂实施流化催化裂化的最佳产能
摘要
流化催化裂化 (FCC) 装置在现代炼油厂的过程中起着至关重要的作用,因为该装置用于生产有价值的炼油厂产品。本研究的目的是研究 FCC 装置中原料的不同容量,并在考虑技术和经济标准的情况下找到最大可用容量。在这方面,该单元的过程模拟是在 Aspen HYSYS 软件中进行的。接下来,将此过程模拟导入 Aspen Capital Cost Estimator(或 ICARUS)以进行运营成本 (OPEX) 和资本成本 (CAPEX) 评估。最后,尝试优化流化床催化裂化工艺的产能。通过调查结果,发现该装置的盈亏平衡点 (BEP) 为每天 30 000 桶。这意味着总成本(运营和资本成本)和净利润(产品收入)相等,并且在比此 BEP 更高的容量下,FCC 装置具有盈利能力。根据经济分析,可以发现 BEP 产能中的 CAPEX 和 OPEX 将分别超过 156 618 948 美元和 37 432 199 美元/年。
