The third series of experiments gave the following results
1. As a
result nonchemical processing crude oil withour industrial machine
there are changes in hydrocarbon composition, which is accompanied
by a significant decrease in viscosity (19%) and the density
total amount of light fractions,
as a result of processing, increased by 3.5%, indicating intensive
degradation of the residual hydrocarbon oil fraction (360 °
C). It should be consider that our tests were carried out with
mixture of crude oil and gas condensate. In this way, the expected
effect on normal or heavy viscous crude oil will be higher.
3. A result
of processing nature oil ( in the selected processing mode ),
the amount of light fractions greatly shifted in the direction
of gasoline. This proves that the process intensive
destruction of hydrocarbon residual fraction 360 ° C.
to form shorter molecules (with the smaller number of carbon
atoms in the molecule) and radicals. As well as facilitating
the fractional composition in the temperature range up to 360
° C, whereby part the diesel fraction of hydrocarbons
goes into gasoline.
As a result
of oil treatment, significantly increased content of hydrocarbons
C5-C6, which are extremely valuable component as a raw material
for the process of isomerization.
the that the amount of the diesel fraction is reduced, low-temperature
properties of future diesel fuels will be much better, by the
significant reduction in the proportion of high-melting paraffins
C20-C24. This greatly influences level of Сloud Point and a
fuel minimum temperature of filterability. At the same time
temperature range of boiling 20% and 90%, determining loyalty
to the action of fuel depressants, it remains unchanged, which
is a very positive result.
is a simultaneous improvement in the low temperature properties
of diesel fuel by reducing the proportion of high melting paraffin
hydrocarbons maintaining high pick-up to the action of depressants
This allows to produce diesel fuel with higher low-temperature
7. If necessary,
the process parameters may be significantly changed, thus intensify
the content of light fractions in the desired temperature range,
to provide individual needs.
Why are we talking about select of individual processing? Example:
a new batch crude oil from "Leninogorskneft" (Tatneft),
obtained the following results:
The density increases, the volume of the gasoline fraction is
not changed, the volume of diesel fraction is increased by 5-7%,
but at the end (340-360 degrees). As a result of the increase
in research of light fractions in the range of up to 360 degrees
increased by 10.2%! The viscosity at 20 Celsius degrees increased
1. Starting point - 85 ° C + 200%.
2. Start point - 150: C + 18%.
3. 85-180: + 9%.
3. 160-360 + 6%.
4. 180-360: + 7.3%.
5. 180-320: + 1.85%.
