Activated alumina may be regenerated to its original adsorption efficiency by heating to a temperature between 350-600°F (177-316°C). of Activated Alumina TABLE 2-7. 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. Application: Adsorbing the alkali in fluid, XR107 activated alumina ball for hydrogen peroxide( activated alumina for H2O2) has the high regeneration capacity for hydrogenation degradation products, and it could transfer the hydrogenation degradation to anthraquinone to insure the stability of antheaquinone The guarantee life of activated alumina. A novel technique to regenerate adsorbent column is presented. Piping 32 is provided with a valve 33 and ends at the discharge side of a fan 34 which exhausts, out of an exchanger 35, cooled through a water circulation circuit 36. Otherwise the residual liquid will react or carbonize upon heating, which will seriously affect the efficiency and operating life of the adsorption cycle. Both heat and/or vacuum can be utilized to bring molecular sieve to a state of being regenerated. A piping 15 connects the base of the cooler 2, through two branch pipes 16 and 16ain which valves 17 and 17a respectively are interposed, with two drying towers 18 and 18a lined inside with a chlorine resisting lining preferably in the form of a brick-work and filled with 1.5 cubic meters of activated alumina which is arranged so as to allow the circulation, in contact therewith, of the cooled chlorine arriving through piping 15. Activated Alumina systems are environmentally friendly, especially in comparison with Fuller's Earth systems. General heating regeneration temperature is … The activated alumina could be used for 2 years or 1800 working hours. Activated alumina desiccant is typically regenerated by your compressed air dryer. Materials and methods Composition of base metal solution .One thus avoids the further presence of the hot and moist chlorine which would deteriorate the alumina during its regeneration and it is possible to use the same charge of alumina almost indefinitely. Manufacturers produce hybrid adsorbents that offer some of the benefits of both activated alumina and molecular sieve, and can tailor some desiccants for a specific application.

Gamma activated alumina(Catalyst carriers), Zibo Xiangrun Environment Engineering Co.,Ltd, Zibo Xiangrun Environmental Engineering co., LTD. New requirements needed to be developed for higher uptake capacity and the ability to remove arsenic cost-effectively without regeneration or creating hazardous waste requiring special handling. In most process plants, adsorbent beds are very reliable and easy to operate, but they do require periodic regeneration. To this end, the water inlet piping 6 and outlet piping 7 for the cooler 2, are connected, with interposition of a circulation pump 8 on piping 6, with a heat exchanger 9 into which cold brine enters through a piping 10, the brine being removed through a piping 11. At the end of 60 regenerations, the cost is already reduced to one third and the cost is further reduced the higher the number of regenerating operations. The water molecules become trapped so that the air is dried out as it passes through the filter. breakthrough, regeneration, and column sizing. Used with regeneration, activated alumina was the accepted best technology when compliance levels were less demanding. 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. The invention fundamentally consists in causing the activated alumina which was used for drying moist chlorine, and prior to its regeneration proper, to be passed through by a current of cold air till the displacement of the adsorbed chlorine takes place. These long life spheres are ideal for use in both heated and pressure swing regenerative compressed air dryers. Fluidized Activated Alumina Fluoride Removal Capacity TABLE 3-1. Regeneration Molecular Sieve, Activated Alumina, and Silica Gel can all be regenerated, meaning they can be treated to remove what has been adsorbed, so that the product can be used repeatedly. Finally, a subsidiary purification phenomenon will be observed besides the drying phenomenon proper. Generally, it uses hot nitrogen for purging desiccant regeneration. Regeneration Molecular Sieve should be in typical cyclic systems constitutes removal of the adsorbate from the molecular sieve bed by heating and purging with a carrier gas. To ensure the above conclusions the following should be fulfilled: 1. Its excellent resistance to fouling by olefins is the reason for its wide use in the treatment of petrochemicals. Two adsorbent filled vessels are installed in a desiccant dryer, one for drying the compressed air and one for regeneration. 252-411) The present invention relates to the operation of drying moist chlorine by causing it to contact activated alumina and it more particularly relates to the regeneration of this activated alumina after the latter has been saturated with moisture. Valves 17 and 20 are first opened, all the other valves being closed and the moist chlorine issuing from electrolysis cells and containing, according to the surrounding temperature 10,000 to 20,000 parts of water for one million parts of chlorine, is fed through piping 5 at the rate of 5 to 7 cubic meters per minute. activated alumina fixed-bed sorption column. Certainly, whatever bad or good, you should use desiccant regeneration for future application. 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. (Cl. 26, 1957 The precooler 1, the cooling of which in, the purified chlorine being removed through piping 21 with a moisture content of to, parts of water for one million parts of chlorine. In the drying of activated alumina,  regeneration of activated alumina is necessary. Heating rate of about 50 â per hour. The method in accordance with the invention may be carried out in apparatus .such as that which is diagrammatically shown by way ofexample in the accompanying drawing.

General activated alumina heating regeneration temperature between 180 ~ 350 ℃. The piping 40 and 40a are provided with valves 41 and '41a' respectively and are connected to a drain piping 42. Ending at the base of the towers 18 and 18a are also pipe branches 22 and 22a which include valves 23 and 23a and which-are connected to a piping 24 connected through a T-shaped connection totwo pipings 25 and 32. You could do it as your requirement. This is normally done by passing a gas stream over the adsorbent at (160-185°C). Piping 25 is provided with a valve 26 and leads to the discharge side of a fan 27 which draws air, through a piping 28, through an air chamber 29 provided with a steam heating circuit 30 and/or with an electric heating device 31. e. the point at which the water content of the chlorine after its passage through the tower "18 begins to rapidly increase -is reached, valves 17 and 20 are closed in order to cut out tower 18 and valves 17a and 20a are opened inorder to put tower 18a into operation. Also, activated alumina is chemically inert toward most liquids and gases. Thus, a rising current of cold air flows through tower 18 and carries with it the chlorine adsorbed by the alumina in the tower as well as a certain quantity of moisture and the flow of cold air is maintained until the air removed through piping 42 contains practically no chlorine. The heating and desorption processes include heating, rinsing and cooling in three steps. 7. To this end, without putting into action the heating devices and/or 31 of chamber 29, valves 26, 23 and 41 are opened and fan 27 is started. A thermostat 12, controlled through a thermo-element 13 immersed in the outlet side of the cooler 2, is arranged in order to regulate the opening of an inlet valve 14 interposed in the piping 10, for the brine.
