4. A case study to consider most of the distillation unit (DU) product streams (5.0 marks) into more process down streams such as reformer, fluid catalytic cracking, delayed coker, and alkylation. The capacity of a DU is 100,000 barrels per stream day. The unit produces raw products, which have to be processed in the downstream unit to produce products of a certain specification. This involves the removal of undesirable components like sulfur, nitrogen, and metal compounds, and limiting the aromatic content. In the case study, 100,000 BPD crude oil is introduced to a distillation column. The produced naphtha cut (190-380°F) is hydrotreated to remove sulfur and then fed to a reformer to produce liquid hydrocarbons. Find the API, classify the type and density of liquid hydrocarbons in lb / cubic feet crude oil having molecular weight of 180.1 kg/kgmole. Given Kw = 12.8
