Abstract

Abstract Many of the modern refineries are founded on converting/upgrading the heavy bases of low value to lighter products by higher added value like gasoline, jet fuel and diesel fuel. In this work, some process configurations in heavy refinery cracking, converting and treating are technically and economically evaluated. In this purpose, four process configurations for refinery plants are suggested. These processes are evaluated and analyzed to obtain the most optimal configurations with the aim of achieving the most valuable refinery products. The difference of the processes is in heavy residue conversion and processing. These processes are included the Asphalt Air Blowing Unit (AABU, Type 1), Delayed Coker Unit (DCU, Type 2), Heavy Residue Hydro-Conversion (HRH, Type 3) and Solvent De-Asphalting (SDA, Type 4). The units are common in mentioned refineries cases and just ABU, HCU, DCU, HRH and SDA are different. In economic consideration, the payout period is considered as one of the standard methods of assessing the economic projects and economically estimating them. As results, the highest rate of gasoline is recorded in the refinery type of DCU unit and the highest amount of LPG/C4/C3, kerosene and gasoline production observed in refinery type of HRH unit. The construction of refinery with ABU unit has minimum investment (980 million $) and highest rate of return (19.4).

重油馏分加工转化为有价炼油产品的技术经济分析

许多现代炼油厂是建立在用汽油、喷气燃料和柴油等高附加值的低价值重基转化/升级为较轻产品的基础上的。本文对重质炼油厂裂化、转化和处理的几种工艺配置进行了技术经济评价。为此，提出了炼油厂的四种工艺配置。对这些过程进行评估和分析，以获得最优配置，以获得最有价值的炼油产品。两种工艺的区别在于重渣油的转化和处理。这些工艺包括沥青吹气装置(AABU, 1型)、延迟焦化装置(DCU, 2型)、重渣油加氢转化装置(HRH, 3型)和溶剂脱沥青装置(SDA, 4型)。这些装置在上述炼油厂案例中是常见的，只有ABU、HCU、DCU、HRH和SDA不同。在经济考虑中，支付期被认为是评估经济项目并对其进行经济估计的标准方法之一。结果表明，炼油厂型DCU装置的汽油产出率最高，炼油厂型HRH装置的LPG/C4/C3、煤油和汽油产出率最高。采用ABU装置的炼油厂投资最少(9.8亿美元)，回报率最高(19.4美元)。
