Boiling point of kerosene fraction
Boilnig point of diesel fraction
According to the density (API degree)light oil
Equipment is usually used for determining oil gravity in the oil field
When the volume of gas is relatively small compared to the volume of liquid, the method used to separate free water, oil and gas is called
When there is a large volume of gas to be separated from the liquid (oil and water), the vessel is called
It is mainly applied when there is a large amount of gas to be separated from a small amount of the light and heavy fluid (less than 10-20% by weight).
It is most efficient where large volumes of total fluid and large amounts of dissolved gas are present with the liquid.
Breaking up a large molecules
The different substances collected from distillation
What is Petroleum Used For?
It is a portable and suitable fuel for light industrial use and domestic heating (cooking)
uses include application in internal combustion engines, commonly used in private and commercial vehicles
Naphta is used:
Oil-water emulsion can be broken by:
Converts low-octane, straight-run naphtha fractions, particularly heavy naphtha that is rich in naphthenes, into a high-octane, low-sulfur reformate, which is a major blending product for gasoline
The raw material OF CATALYTIC REFORMING
Temperature at the top in a absorber of catalytic reforming process
Pressure in a absorber of catalytic reforming process
Why do we need to hydrotreated naphta material before reforming?
Catalyst of catalytic reforming
Catalyst of catalytic cracking process
The reaction products are separated from the catalyst dust in two-stage cyclones and sent to the bottom of the K-1 distillation column for separation
This units have the same type of fractionation scheme for cracking products and differ mainly in design and the principle of the reaction block
Large hydrocarbons are broken into smaller molecules using heat and a catalyst
Breaking up a large molecules
the different substances collected from distillation
Process flow diagram of a catalytic cracking unit with a once-through lift reactor
Feedstocks of catalytic cracking are typically
in which the water-oil emulsion is destroyed in an electric field with a strength of 1-3 kV / cm
Fresh wash water is supplied by pump 15 to heat exchanger 10' heated to
According to the density (API degree) heavy oil
Naphta is used
The desalinated oil pumped by pump 8 passes through a group of heat exchangers 10, 11, 23, 26, 29 in two parallel flows and heated to a temperature
Distillation column 2 operates at an overpressure reaching at some plants
Vapors of light gasoline the end of boiling of this fraction in some cases is
the main purpose of this process was to obtain an additional amount of gasoline from heavy oil residues, which, compared to straight-run fractions, has increased detonation resistance, but low chemical stability
CATALYST OF THERMAL CRACKING PROCESS

Make the correct judgment: A) oil distillation is a physical process; B) cracking is a physical process
Rectification gases formed during oil distillation mainly contain
As the number of carbon atoms in hydrocarbon molecules increases, the boiling point of these hydrocarbons increases
Specify the oil fraction with the highest boiling point
Specify the fraction of oil with the lowest boiling point
Specify the physical method of oil refining
In thermal cracking, two molecules are formed from onealkane molecule
The detonation stability (octane number) is higher for gasoline produced in the course of
The process of obtaining 2,2,4-trimethylpentane (isooctane) from normal octane: CH3-CH2-CH2-CH2-CH2-CH2-CH2-CH2-CH3 (CH3)3 C-CH2-CH(CH3)-CH3is a process
