Abstract—The comparative analysis of the molecular mass distribution, temperatures and heat effect of phase
transitions, degree of crystallinity of defect materials and matrix polyethylene ﬁ lm were carried out. Possible
reasons of deterioration of the quality of polyethylene on stages of its synthesis, transportation, storage, and
processing were determined.
Producing in year 2008 224 ktons of low density
polyethylene the “Tomskneftekhim” Ltd. became the
№1 producer of this polymer in Russia as well as in
CIS even taking into account its closed production in
Severodonetzk with project capacity of 216 ktons. From
four installed plants of “Polymir” technology elaborated
together with specialists from USSR and DDR, the
better results were achieved only on plant “Polymir-60”
in Lane (Dow Chemical) which has the output more than
120k tons per year on one “line”, although improvements
of technology are being done since 1980. German
colleges consider works of Professor Ipatiev V.N.
with collaborators on ethylene polymerization under
high temperatures and pressure executed in chemical
laboratory of Saint-Petersburg Artillery Academy and
published in Journal of German Chemical Society [1, 2]
as the beginning of collaboration with specialists from
Other lines with tubular reactors operating in the
country which has been built by “Salzgitter” technology
in 62–65 and 72–75 years are uncompetitive, therefore
“Polymir” technology will keep its leading positions
during next years till putting into operation the production
with capacity of 300 ktons by “BASF” technology in
New Urengoy. There are no other intentions to create
new HPPE productions; and this conforms to a world
practice where growth capacity does not exceed 1% (the
lowest among thermoplastics) in conditions of sharp
competition with linear polyethylene of low density for
application ﬁ elds and markets.
In creation of new economic HPPE productions with
tubular reactors there is a tendency of the production
capacity increase in the world up to 300–400 ktons
(for example, in Aubette, France, 320 ktons/year, by
BASELL technology “Lupotech T”, and in Wilton,
England, 375 ktons/year, by company Huntsman ).
The development of metallurgists in production of pipes
for reactors with inner diameter up to 100 mm calculated
for operating pressure up to 3500 at with elaboration
of hyper compressors with capacity by ethylene up to
130 tons/hour, and with the use of multizone technology
(4 and more feeding points of initiator and ethylene)
with the use of initiative “cocktails” contributed to it.
The competitiveness of existing lines of low
productivity is provided by their modernization in order
to increase the capacity with minimization of costs.
This allows to decrease exploitative costs per unit with
retaining (improving) the quality of production, and to
develop new “premium” brands of polymers.
The increase of ethylene conversion is the well
known way to increase the output of existing plants with
deﬁ ned admissible parameters of work of reactor block,
recycling systems of high and low pressure, capacities of
compression equipment. The increase of the conversion
occurs together with decrease in the high pressure
recycling ﬂ ow (approximately round 250 at) and energy
