Taking a crude capacity of 5 million t/a grassroots refinery for processing a mixed crude of 80% Arabian light and 20% Arabian heavy crudes as an example, 5 processing schemes with ARDS or VRDS were technically and economically compared.

• 以80%25的阿拉伯轻质原油和20%25的阿拉伯重质原油的混合油为例，对一个原油加工能力为500万t/a的新建炼油厂采用ARDS（常压渣油加氢脱硫）和VRDS（减压渣油加氢脱硫）5种不同的加工方案进行了技术经济分析。
