ecology
DENOX process
This demonstration experiment for removing nitrogen oxides from flue gas
(DENOX process) provides an insight into the mode of operation of largescale
plants, thus familiarizing the students and trainees with practical procedures.
The industrial-scale removal of nitrogen oxides from flue gas
involves allowing NOx to react with atmospheric oxygen and either ammonium
or urea as a reducing agent in the presence of a catalyst using the SCR
method (selective catalytic reduction). The reactants react on the catalyst to
form environmentally compatible substances.

Stack gas desulfurization
Stack gas desulfurization plants have now become virtually standard equipment
for coal-fired power stations. The sulfur dioxide liberated when fossil
fuels are burned, a major cause of acid rain, is precipitated as CaSO4 . The
process can performed quite simply in the experiments.
