Description
On the basis of the technology there is a method of recycling
the rubber containing waste in atmosphere of hydrocarbon
thermophore with the end product of high liquidity, demanded at the
raw material market. The essence of the process is in
following:
Raw material (tyres and other rubber wastes) primarily
shredded to a crumb sized up to 5 mm. and eliminated from metallic
and textile cord fabric. Crumb goes to reactor (R1) with
hydrocarbon thermophore circulating inside the cham¬ber. While
flying along the reactor the crumb gets heated and this process is
followed by decay (thermolysis) to dry (carbon black) and liquid
(hydrocarbon gas) fractions.
Dry fraction is afterwards pushed into carbon purification
reactor (R2) and gaseous part goes directly to fractionating column
through the filter (actually being an original invention of B OJSC
"NPP Termoliz") where it decomposed into synthetic oil, gasoline
fraction and pure gas. Gasoline fraction being a heat carrier is
later forwarded for circulation and synthetic oil goes directly to
storage facility. The rest of the gas is compressed in compression
chamber and served for ilter regeneration purpose.
Carbon black, after being purified, is then sent to the packer
and further on - to warehouse.
Synthetic oil. All properties are identical to those of the
natural oil and even exceed them in contamination of sulfur (0,4%),
absence of water and lamp wax. Synthetic oil is accepted by oil
processing units/plants.
Carbon black. Around *0% of carbon black on the market is used
to produce tyres. It is widely used in electrical industry in
manufacturing some types of alloys and special paper, as a colorant
in various dyes, polishes, plastics etc..
