Components for measuring gas drying and cleaning
From the reactor the measuring gas is fed to the condensation coil attached to the rear of the
automatic TIC solids module. The measuring gas is cooled down quickly in the condensation
coil and the water vapor condenses. The measuring gas/water mixture is passed via a hose
to the gas/liquid separator consisting of a condensate container and a Peltier cooling block.
The measuring gas is passed to the condensate container through the side entrance. The
measuring gas is dried by freezing in the cooling block. The dry measuring gas is routed via
the top connection out of the condensate container. After each measurement the condensate
pump pumps the condensate draining through the bottom outlet automatically to the waste
container.
The measuring gas is finally passed through the drying tube filled with magnesium perchlo-
rate. This concludes the drying.
The gas path contains a halide trap (U tube) after the measuring gas drying process for the
greatest possible removal of interfering components in the measuring gas and to protect the
detectors and the flow meter in the C/S module. The U-tube is filled with special copper wool
and brass wool. The filling of the halogen trap has to be renewed at the latest once half of
the copper wool or the brass wool is discolored.
