Title: Technology of thermal processing of organiccontaining raw materials. Unit with solid heat carrier UT


1
Technology of thermal processing of
organic-containing raw materials. Unit with
solid heat carrier (UTT).
Prof. E.P. Volkov, Director of Power
Engineering Institute (ENIN) Moscow, Russia

Russian technology of pyrolysis development
and maintenance
Technology of oil shale pyrolysis was
successfully mastered and introduced in
industrial scales at the unit UTT-500 processing
500 t of oil shale per day and that at the
unit UTT-3000 processing 3000 t per day.
Two units UTT-3000 were put into operation in
1987 at the Power plant at city Narva, Estonia
(in the time of former USSR). It demonstrate
successful experience of thermal processing of
Baltic oil shales as well as of waste automobile
tires, solid and liquid organic waste in a
mixture with oil shale. The result is the
obtaining of high calorific liquid and gaseous
fuels as well as the very valuable chemical
products.

Unit UTT-3000 in city Narva for thermal
processing of oil shales
Two units UTT-3000 in Narva take up to now the
leading place in the world as to the quality of
oils and gas obtained from oil shale,
ecological indicators and economic efficiency.

Unit UTT-3000 for thermal processing of oil
shales
? The main advantage of pyrolysis by means of
units UTT is a possibility of oil shale
processing of any fractional composition
and quality
Only the oils shales with calorific value lower
than 2.9 MJ/kg require the supply of additional
fuel for processing that is necessary for
supporting the pyrolysis process.
For reference Heat of combustion of Baltic oil
shales for
Estonia and Leningradskaya region of Russia is

8,37 MJ/kg

Unit UTT-3000 has the following advantages?
  • ? The heat of combustion gas obtained after
    pyrolysis in units UTT is in 2.5-3.0 times
    more than in the plants of other countries.
    So, the calorific value of pyrolysis gas after
    the processing of oil shale of
    Leningradskoye deposits is 42,2 MJ/kg.
  • ? The gas obtained in the units UTTs represents
    the marketable product - a fuel for gas
    turbines, while in other technologies the
    considerable part of gas is used in the
    cycle itself for combustion in the reactor.
  • ? The utilization of ash instead of gas for
    pyrolysis increases the efficiency of inits
    up to 84-89, while the efficiency doesnt
    exceed 65 for the majority of plants of
    other types.
  • ? The total efficiency of cleaning of gas-vapor
    mixture in cyclones achieves 99,5. Owing
    to it, the content of dust doesnt exceed
    1.0-1.5 even in the heavy fractions of oil
    shale.
  • ? The inits UTT-3000 process the waste
    automobile tires in a mixture with oil
    shale. The processing of grounds saturated by oil
    products (for example, because of accidents
    during transportation) is also technically
    possible and was confirmed in practice.
