Fixation of Thermocouple’s Site and Established Value in Course of Desorption of Gold-Loaded Carbon

Abstract:

Based on industrial experiment and analysis of theoretical calculation, the paper shows that it will be always unsuitable for thermocouple to be fixed on any sites of the desorption column if the established value of temperature-controlling apparatus is just the same temperature as is required to desorption process. When the thermocouple is fixed on the bottom of the desorption column or on any sites of the heating apparatus, the heating apparatus will have to switch frequently. The result should also be avoided in production concerned. The site of the thermocouple and its established value can be only determined finally through industrial experiment and theoretical calculation since they are connected with many conditions necessary to the desorption operation.
