THERMAL NEUTRALIZER OF INDUSTRIAL WASTEWATERS
FOR POWER-, HEAT-, AND WATER-SUPPLY SYSTEMS
OF OIL AND GAS ENTERPRISES
I. V. Dolotovskii UDC 658.261:665.6/.7.002.8
A design for a neutralizer of industrial wastewaters that complemented power-, heat-, and water-supply
systems of oil and gas enterprises was proposed. A scheme of a neutralizer with thermal destruction of
efﬂ uents and gaseous and liquid combustible wastes and container disposal of the resulting dry residue was
presented. Technical solutions that made it possible to achieve the lowest speciﬁ c fuel consumption among
known designs and to increase the energy efﬁ ciency and environmental safety of oil and gas enterprises
Keywords: industrial waste, thermal destruction, oil and gas enterprise, power- and water-supply systems,
The energy efﬁ ciency and reliability and the environmental safety of oil and gas enterprises (OGEs) are determined
mainly by the equipment and the operating modes of the power-, heat-, and water-supply and sewer systems (PHWSS). Use
of new scientiﬁ c and technical solutions in PHWSS and incorporation of power-saving units and combinations  could
provide not only improved power and environmental parameters for effective OGE operation but also reduced production
costs for the main product and labor costs for operations.
Thermal neutralizers for industrial wastewaters (TNIWs) are devices constructed according to the standards  for
thermal destruction of liquid industrial wastewaters (IWs) that are aqueous solutions containing dissolved and suspended
combustible components and mechanical impurities. The nontoxic (or slightly toxic) dry residue formed by thermal destruc-
tion of these wastewaters should not contain As, Sb, Hg, and their salts . The advantage of TNIWs, which were preferred
for assembling power plants (Patents 114424, 118360, 134993, 138474, and 164323, Russia), is their ability to operate at all
stages of the OGE life cycle.
Costly equipment and infrastructure (disposal wells, heated pipelines, high-pressure pumps) can be obviated if ther-
mal destruction of IWs is used. Transportation and underground burial of IWs in absorbing strata are not required. High op-
erating costs associated with clogging of disposal wells are avoided.
Installation of neutralizers at OGEs, which are simultaneously fuel sources (liquid or gaseous) and IW generation
sites, enabled the problems of recycling combustible wastes and IWs to be solved together.
TNIWs with container removal of mechanical impurities (Fig. 1) satisfy to a large extent the regulations  and are
protected by a Russian design patent . This TNIW was designed for thermal (ﬂ ame) destruction of industrial (and house-
hold, if necessary) wastes at crude-oil ﬁ elds and reﬁ neries, gas trunk-pipeline compressor stations, and in bedroom commu-
nities near such sites using combustible wastes from the main production.
