IMPROVING THE PROCESS OF VACUUM DISTILLATION OF FUEL OIL KURMANGALIEV A. S.
Master’s student, Toraighyrov University, Pavlodar The article discusses options for improving the process of vacuum
distillation of fuel oil. Various variants of the process are analyzed.
Keywords: vacuum distillation, AUTH, improvement, nozzles,
mechanical activation.
Currently, due to the modernization and construction of new
catalytic cracking plants, it is possible to process vacuum gas oil with
a boiling point of up to 360 °C. This, in turn, increases the resource of
vacuum gas oil raw materials, as well as increases the viscosity of tar
and allows it to be used in a larger composition of road bitumen without
oxidation [1, p. 12].
An important task is also to increase the productivity of already built
ELOU-AVT installations, including when changing the composition of
raw materials, for example, in the direction of increasing the content of
light and heavy vacuum gas oil in it.
The aim of the work is to find ways to improve the process of
vacuum distillation of industrial analog fuel oil at the ELOU-AVT-1 unit
with a fuel oil capacity of 2.8 million tons/year. The process is carried
out under vacuum in a column equipped with a regular nozzle QtY.
The analysis of the production method showed that the main problems
arise when providing a high proportion of distillation without noticeable
decomposition of hydrocarbons with minimal liquid entrainment to the
lower plate, as well as the use of contact devices with low mass transfer
efficiency and high hydraulic resistance. To achieve the purpose of
the work, we will consider the main directions of modernization of the
process of vacuum distillation of fuel oil.
The increase in the selection and improvement of the quality of
vacuum gas oil in new and upgraded AVT installations is determined by
the capabilities of the equipment of the vacuum unit of these installations,
as well as through the introduction of a set of measures:
