The composition of this line includes plasma-optical camera and monitoring unit off-gas with
an actuating device switch thread. In normal operation of the plant gases through the unit for
monitoring and flow-switching device is discharged into the atmosphere.
When issuing a unit signal for excess levels of incomplete combustion produces a signal to
the actuator to switch the direction of flow and the additional stage of gas purification.
After the normalization process of gas purification in the absence of a signal from the
monitoring unit flue gas by switching the flow to discharge into the atmosphere.
All the techno-economic and environmental performance of the disposal of persistent organic
pollutants were confirmed in a laboratory setting using a full-scale specimens of PCBcontaining
wastes.
11.3.4.2 Stage of PCB-waste sulphonation with further neutraliztion by salt-forming agent.
Select the direction of the third stage of technology, as mentioned above, determined by the
concentration of PCB-containing liquids. When the concentration of active ingredient of PCB
for more than 90% used mobile installation, which uses technology oleum sulfonation
followed by treatment with salt-forming agent (method sovtol patent RU 2341509 C1) [52].
The process involves sulfonation with oleum excess sovtol relatively oleum at a temperature
of 100-180 ° C and subsequent neutralization of the salt-forming agents - triethanolamine.
Sulfonation reaction is carried out at a molar ratio sovtol: oleum of 1: (from 0,55 up to less
than 0,6), after neutralization of the reaction mixture was extracted with a solvent free sovtol -
tolueneom, whose amount is equal to 0,75% of the initial mass sovtol after then extracted with
toluene sovtol regenerate, bottoms - sovtol return to the stage of sulfonation, and toluene on
the stage of extraction.
Block diagram of sulfonation of PCB wastes, followed by neutralization salt-forming agent is
shown in Figure 11.3.7.
