Method and device for detecting moving objects in a gas stream during cryogenic gas separation

The invention relates to a method for separating gases of a gas mixture in the form of a gas stream, wherein the gas stream is irradiated with electromagnetic emission radiation (12) in the microwave or terahertz range and scattered radiation (13) is detected, the scattered radiation arising due to...

Beschreibung
Zusammenfassung:	The invention relates to a method for separating gases of a gas mixture in the form of a gas stream, wherein the gas stream is irradiated with electromagnetic emission radiation (12) in the microwave or terahertz range and scattered radiation (13) is detected, the scattered radiation arising due to scattering of the emission radiation on at least one object (11) in the gas stream, a frequency difference between the scattered radiation and the emission radiation is detected, from which frequency difference a presence, a number and/or a proportion of moving objects in the gas stream is determined and the gases in the gas mixture are separated taking into account the determined presence, the determined number and/or the determined proportion of moving objects in the gas stream.
