Appeal No. 2005-0715
Application No. 09/725,428
operating parameters of the waste gas purification system.
Further details of this appealed subject matter are set forth in
representative independent claim 1 which reads as follows:
1. A method for purifying process waste gases
containing selected harmful substances comprising:
introducing the process waste gases with
combustible gas and oxygen into a waste gas purification
system having a combustion chamber, an exit, and operating
parameters, including amount of combustible gas and amount
of oxygen;
post-treating reaction products leaving the
combustion chamber in a sorbtion chamber with an associated
washing agent circuit containing washing agent having a
selectable pH;
measuring with a first detector the type and
amount of selected harmful substances in the process waste
gas before said waste gases enter the waste gas purification
system to generate first measuring signals;
determining with a second detector the type and
amount of selected harmful substances of the reaction
products leaving the waste gas purification system at the
exit of the purification system to generate second measuring
signals; and
directly using the first and second measuring
signals for adjusting the operating parameters of the waste
gas purification system, including amount of combustible
gas, amount of oxygen, amount of washing agent in the
washing agent circuit, and pH of the washing agent.
