The refinery process when you have completed the section you should be
familiar with simple refining semi complex refining complex refining
in this section the refining of residual fuel oils will be described the
particular emphasis on the origin of both residual and Dilli whant components
we will begin by briefly describing the configuration of Noida finally and
highlight the main process units to utilize fully the potential of crude oil
it is necessary to separate this constituents into a number of fractions
this is the objective of oil refining refinery's can be divided into three
different categories
simple refinement
the foundation of the refinery is the atmospheric distillation unit
the fractions obtained through atmospheric distillation are gases such
as ethane propane butane
light distillates such as gasoline NAFTA chemical feedstocks kerosene for
domestic and aviation fuel gas oils for diesel engines domestic and industrial
use
long residue for fewer lawyers loves feedstocks waxes bitumen conversion
simple refining is also called primary refining and are used for physical
separation of different crude oil fractions separation pressure is
atmospheric the separation temperature is below 350 degrees Celsius semi
complex refining
the semi complex refining process is characterized by the thermal gas oil
unit which is similar to this breaking
residue from the first stage is vacuum flashed heavy distillate from the first
stage is cracked in a second furnace at a temperature 500 degrees Celsius and a
pressure of 20 to 25 bar viscosity of the residue varies
a complex refinery uses a combination of physical separation and chemical
conversion processes
hydro treatment is used to reduce the sulfur content
simply refinery long residue from the atmospheric
distillation unit is diluted with gas oil semi complex refinery the fuel oil
would generally comprised residue from the thermal gas soil unit debuted with
thermally cracked gas oil generally some residue and diluents from the
atmospheric distiller will also be incorporated complex refineries a fully
complex refinery include all the processes there's a wide range of
residues and diluents are available
