Abstract—An experimental study of the kinetic stage of combustion fumes of organochlorine wastes. We obtained
the data on the normal speed of propagation of the ﬂ ame, and other parameters of the ﬂ ame front. Also we found
an effective constant of the reaction rate and determined requirements for reactors of a high-temperature oxidation
of organochlorine waste.
To date the problem of waste processing of poly-
vinyl chloride, epichlorohydrin, chloromethanes
manufactures is among the most important problems
of environmental safety. Tens of thousands of tonnes
of organochlorine compounds were accumulated on the
chemical manufactures producing chloromonomers and
chloropolymers, and they already seriously threaten to
environmental safety in several regions of Russia.
A large number of studies are known which suggested
various ways of organochlorine waste (OCW) trans-
formation into useful commodity products: perchloric
compounds, amines and polyamines, alcohols etc.
On composition OCW somewhat differs for the
various manufactures. In polyvinylchloride industry
50–70 kg per each a ton of a target product is formed of
anhydrous OCW, and in epichlorhydrin industry the OCW
part is much more and consists of 250–300 kg/t. Thus the
total volume of the formed in Russian manufactures is
about 100 thousands tones per year. OCW on chemical
composition is a mixture of saturated and unsaturated
chlorohydrocarbons. The toxicity of the distinct
components corresponds to 1–3 hazard class. Nowadays
25–30% of OCW are combusted obtaining so-called
waste hydrochloric acid of an average concentration,
demand for which is limited due to its low quality, but
the main part is pumped into the underground duffers of
an extraction of sodium salt.
In this paper we studied a way of OCW processing
by its combustion in an oxygen-containing environment.
The formed hydrogen chloride is suggested to produce
as marketable products: dry hydrogen chloride and
concentrated hydrochloric acid. Other products of the
combustion, carbon dioxide and nitrogen ballast after
sanitary post-treatment in alkaline scrubbers can be
removed in atmosphere.
In real industrial reactors (furnaces) for combustion
of liquid products occur complex physical-chemical
processes: atomization of the liquid phase in the jets, the
formation and evaporation of the torch drops, ignition and
combustion of fumes. The processes of sprinkling and
evaporation of liquid droplets were studied in a sufﬁ cient
detail for various media, but the combustion, or more
correctly chemical transformation, can not be predicted
theoretically because of no data on the rate (kinetics) of
A reaction model for the products consisting OCW
(chloropropanes, chloropropenses) are very complex,
but this process can be divided into stages: abstraction
of hydrogen chloride, e.g.,
and combustion of the formed hydrocarbon:
