Heating rate of about 50 ℃ per hour. 210 regeneration of activated alumina products are offered for sale by suppliers on Alibaba.com A wide variety of regeneration of activated alumina options are available to … The water in the air will stick to the alumina as the air passes through it. Activated Alumina Fluoride Removal We will explain it in our next news. This process is called regenerating the desiccant. This article, Part 2, covers the most widely used adsorbents — in order of decreasing commercial importance (2, 3): activated carbon, zeolite molecular sieves, silica gel, activated alumina, and polymeric adsorbents — with discussion of their physi- This apparatus which constitutes a complete plant for drying chlorine issuing from electrolysis cells first comprises, mounted in series, a precooler 1 and a cooler 2 for the chlorine. The temperature of the activated alumina tower is generally raised to 280 ° C for 4 hours. The present invention makes it possible to remedy this disadvantage and, on the contrary, to render the drying of chlorine with activated alumina less expensive than the drying with sulphuric acid. Otherwise the residual liquid will react or carbonize upon heating, which will seriously affect the efficiency and operating life of the adsorption cycle. The chlorine is cooled in passing through the unit precooler 1 and cooler 2, thermostat 12 being set in order to control the opening of the valve 14 and, accordingly, the quantity of brine passing through exchanger 9 so that the cooling water in cooler 2 is brought to a temperature of the order of 8 to 9 C. in order that the temperature ofthe chlorine at the outlet from cooler 2 is about 10 to 12 C. The chlorine which then shows a constant moisture which is of the order of 3,000 parts of water for one million parts of chlorine, passes through tower 18 in which the activated alumina adsorbs the moisture of the chlorine as well as the organicimpurities contained there- Patented Mar. After the regeneration of the active alumina bed must be cooled before the adsorption operation, with the cooling gas to wash the bed, the gas should also be used to try not to contain water, cold gas flow and adsorption cycle of the same direction. The heat removes the small water vapors and droplets that are trapped inside the tiny holes of the activated alumina. The higher the heating temperature, the more complete the desorption regeneration. 14, 1953 ilnited States Patent METHOD OF REGENERATING ACTIVATED ALU- MINA CONTAINING ADSORBED MOISTURE AND CHLORINE Jean Gurin, Jarrie,'France, assignor to Societe dElectI-o- Chimie, dElectro-Metallurgie et des Acieries Electriques dUgine, Paris, France, a corporation of France Application December 14, 1953, Serial No. If you have any questions on activated alumina regeneration, you could find Zibo Xiangrun Environment Engineering Co.,Ltd. Efficiency of Activated Alumina Regeneration, TABLE 2-8. General heating regeneration temperature is … In any case the leaching of impurities and aluminium from the activated alumina i… The organic impurities of-the chlorine are adsorbed by the alumina and desorbed with a partial decomposition at the time of the regeneration. Regeneration is a chemical procedure used for cleaning up the used activated alumina, so that it can be reused. The vessels are switched from on-stream drying service to off-stream regeneration alternately. Refer to a typical regeneration scenario below: But Good quality activated alumina performance could improve the life and drying situation. The process used is based on the utilization of an electrochemical cell which regenerates several saturated adsorbent bed. The regeneration may be carried out by passing the spent alumina adsorbent through a heated tower or kiln concurrent or countercurrent to a stream of dry oxidizing gas, the gas charged to the tower or kiln having a moisture content not greater than 3 milligrams per … Product Description 6-8mm regeneration desiccant activated alumina ball msds Xintao Activated Alumina with high strength, low abrasion, no soften in water, no expansion, no powdery and no crack. As soon as the temperature reaches 30 C. in tower 18, valves 33, 23 and 39 are closed and said tower is again available for a drying cycle of moist chlorine. Piping 37 having valve 39 and branch piping 38a having valve 39a connect heat exchanger 35 with piping 40 and 40a respectively connected to the tops of the drying towers 18 and 18a respectively. Under these conditions, the method for drying chlorine with activated alumina is less expensive than the method using sulphuric acid, as soon as the number of cycles exceeds-twenty. The zone which is saturated with moisture sinks little by little in the tower 18 and, after '24 hours and before the breaking down" pointi.
