Abstract
At present, the production of motor fuels is associated with the compounding of
products of reforming, isomerization, catalytic cracking, hydrocracking and
hydrotreating. The quality of the components of motor fuels obtained in the
above processes strongly depends on the rectification sharpness of raw materials
and the stabilization of end-products. The existing lack of rectification sharpness
worsens the economic parameters of the production of motor fuels and their
operational and environmental properties. This problem results from the
insufficiently effective interaction of the vapor and liquid phases in the contact
devices of distillation towers. Here, we prove the necessity of taking into account
the diffusion of key components of distillates between the vapor and liquid
phases and the surface phenomena at the phase boundary in contact devices.
Increasing the operating pressure in distillation towers and the introduction of
surface-active substances per residue leads to a high degree of separation of
distillates during their rectification. This technique has successfully been tested
on the manufacturing facilities of a number of primary oil refining and gas
processing plants. An industrial implementation of these findings will enable the
improvement of the economic parameters of production of motor fuels and their
operational and environmental properties.
Keywords: quality of motor fuels, rectification, rectification sharpness, process
of mass transfer, surfactants.
