In practicing the subject methods, an initial multicomponent gaseous stream is contacted with an aqueous fluid under conditions of selective CO2 clathrate formation to produce a CO2 clathrate slurry and CO2 depleted gaseous stream. The modulators transmit the signals on various frequencies. A screw back out prevention mechanism adapted on the plate portion and prevents the back out of screws from the screw holes.
