Method for recovering and/or removing organic compounds from gas streams

A travelling bed drier is disclosed, for operation of a carbonization or coking plant in which pre-heating of coal is performed. Adapted so that a fluidized bed drier can be superposed thereon, the travelling. bed drier possesses a heat exchange tube within a frame, the tube displaying a surface increased through suitable design such as fins or ribs, a conical tapering in the direction of the coal feed, and discharge connections located at different levels on a side of the frame lying opposite vapor or hot gas entry, the connections being for the discharge of exhaust gas-containing vapors.

The interior space of a combustion chamber, boiler, or other such gas-filled chamber exhibits an acoustic response spectrum to acoustic energy excitation which includes plural maxima attributable to acoustic natural-vibration frequencies. The frequencies of these natural vibrations are dependent upon both the interior temperature of the chamber and also upon the normality or molarity of the gaseous contents of the chamber. One of these two variables, i.e., temperatures or else normality or molarity, is measured by conventional devices. The other variable is then measured using a pressure transducer generating an electrical signal indicative of the chamber interior's acoustic response spectrum, the transducer output signal being applied to a discriminator circuit which develops a measurement signal indicative of the value of the variable being measured. In this way, interior temperature can be continuously monitored by acoustic devices with high accuracy.
