Facilities Engineering - Coursework Example here atomic number 18 the CPR results obtained for fossil oil colour and gas exploration Figure 1 CPR results of Gas and fossil oil extracted from Gazelle Well Major products extracted out of the oilfield at Gazelle are liquefied petroleum gas, gasoline, diesel fuel, fuel oils, lubricating oils, alkane wax, sulfur. Question Prepare flow schemes showing the architecture of the layout and of the main components used from the wellhead to the point of export for exclusively option. The architectural layout of the Gazelle offshore oilfield is shown below with all the processing building blocks and their respective processing cycles. This is a very large operating unit with extensively large piping layout with fluid streams running along. Crude oil is first passed through an oil production unit which provides the pre-processed oil to the oil storage tank from where it is delivered to the processing plant through a piping system. Here is th e detailed flow diagram of all the processes taking place along their sequential flows Figure 2 Flow Diagram of Gazelle Oilfield with components used in Oil Production Gazelle oilfield is a field that requires extensive production as well as operational refurbishments but even consequently it is higher up working above case base oil producing offshore refineries. This oil production unit involves a number of operating units that work extensively for long hours to provide flavor product in economical rates with least water cuts. Following is an exhaustive list of components that work as a part of oil refinery at Gazelle(Snow, 2010, Gordon, 2012). De-salter unit is just provided at the inlet of crude oil and is responsible for washing away all the salt from crude oil. Distillator Crude oil from de-salter is then passed through the distillatory unit which distills the crude oil into fractions. Second stage of distillation is also incorporated just after this by making use vacuum cl eaner distillation unit which is responsible for the distillation of the left over components of crude oil which were not fractioned by simple distillatory. Hydrotreater all fractions of the crude oil are then hydrogenated according to their requirements and this process is performed for removing sulfur contents from the oil fractions. catalytic Reformer it is used to reform the low point oil fractions into high grade products like converting gasoline to a higher degree of octane level. While reforming the oil fractions excess amount of hydrogen is produced as a by-product of the process. Fluid Catalytic Cracker this catalytic cracker is specialized in converting only liquid oil fractions to higher grade of oil. The process of converting gasoline to hi-octane is processed there. Hydrocracker hydrocracker then takes the oil fractions and hydrogenizes them in order to upgrade the fractions. Visbreaking the oil fractions that are needed to be degraded to lower order fractions are then passed through visbreaking unit Coking unit this unit is specialized in carbonizing the heavy oil components of the fractions in order to produce gasoline. This helps in converting maximum oil fractions into consumable products. Alkylation this unit is specialized in converting low grade molecules to higher ones and hence improving the quality of gasoline. Dimerization the process of dimerization is performed in order to hydrogenate the gasoline products. Isomerization unit This unit is specia
