NOx and dinitrogen oxide separation
according to requirements by TA – air
intended amendment of TA-air presumes a reduction of NOx- in the waste
gas and presents for the first time a limit value of N2O. Therefore,
for this reason for separation of NOx from waste gas new equipments
can be built only by means which all limit values are maintained. It
is necessary to re-design the existing plants and equipments.
The catalytic purification
of waste gas takes place in both the processes at different temperatures.
While the conversion of N2O takes place at temperatures of about 400°C
only NO and N2O can be transformed in a catalytic way already at temperatures
starting from 150°C. It is necessary to use a reduction agent for
catalytic transformation of NO and NO2 . In comparison with it, in case
of catalytic transformation of N2O it is not necessary to do it in this
way. However, the reaction can be accelerated markedly by using appropriate
from waste gas for high-temperature process.
from waste gas for low-temperature process.
|Both the variants can be used for a rate of flow of waste gas of 100- 200.000 Nm³/h . With the use of special honeycomb-type catalysts it is possible to attain extremely low pressure drop values. Get yourselves our lead from technology point of view. Other information you can find under KZ.|
