Ethylene for industrial use — Determination of traces of polar compounds — Preparation of condensate...
Specifies a method of sampling by scrubbing at dry ice temperature (195 K). Permits the concentration of traces of all the less volatile polar compounds (water, alcohols, esters, acids, amines, etc.) in a small amount of liquid phase practically without any interference due to adsorption phenomena on the relatively small internal surfaces of the scrubbing absorber. This sampling technique permits…
Light olefins for industrial use — Determination of water — Guidelines for use of in-line analysers
Gives methods for the determination of water using an analyzer with an in-line sensor in gaseous flows of the substance to be analyzed. Compiles the various principles of working of the most generally used commercial analyzer like electrolytic decomposition - light reflection on a cooled mirror (dew-point) - modification of vibration frequency of a quartz crystal covered with a hygroscopic layer…
