Water washing, cooling with water at +8°C, asbestos mist removal, four-stage sulfuric acid tower drying, acid mist removal, chlorine compressor. Chlorine vapor ≤100ppm
Water washing, circulating water cooling, 5-degree water cooling, water mist removal, three-stage sulfuric acid drying, acid mist removal, turbine transportation. Chlorine content ≤100ppm
Water washing, primary cycle water cooling, secondary 4-degree chilled water cooling, water mist collection, tertiary foam tower sulfuric acid drying, drying tower sulfuric acid drying, acid mist collection, and transportation via Na-type pump. Water content in chlorine ≤ 100 ppm
After treatment, how do you measure the moisture content in your chlorine gas? Both the weighing method and potentiometric titration are troublesome, lacking in timeliness and accuracy. It would be great to have an online instrument for measuring trace moisture levels; if you have any suggestions, please contact me at match_0@163.com
If a centrifugal compressor is connected after drying, the water content must be <30 ppm; otherwise, it will cause severe corrosion to the compressor. The drying tower comes in a three-in-one version, with two layers of washing + one layer of bubble packing. Actually, none of this is crucial; based on my design experience, once the tower’s design is finalized, the key component is the demister.
Why must the moisture content in centrifugal compressors be below 30PPm? In most cases, such specifications are required by the equipment manufacturers; for production purposes, these requirements are not that strict. I feel that a score below 150 isn’t too bad either. The drying process typically involves a filler plus bubble columns; those who have read \"Chlorine Drying and Demisting Technologies\" can see that the design of the tower is crucial for drying, and I don’t think the key lies in the demister.
I agree with the view above: the water removal during the drying of chlorine gas occurs in stages, with different amounts of water being removed at each stage. The amount of water removed through cooling and in the packed tower is relatively high, while in the bubble column, water removal is aimed at further reducing the moisture content in the chlorine gas. Because the driving force for mass transfer has decreased, only a small amount of water can be processed. This post was last edited by limingshuguang on 2008-3-8 11:54.]
The quality of the drying effect depends crucially on the control of the temperature and concentration of sulfuric acid during the drying process. The general procedures are similar; to remove moisture from wet chlorine gas, the level of control lies in the temperature and concentration of sulfuric acid, as these determine the vapor pressure of water in the chlorine gas. Appropriate temperature control has a direct impact on the amount of moisture contained in the chlorine gas. Last edited by limingshuguang on 2008-3-8 11:55.]
Which company makes better chlorine drying equipment?
Washing tower, titanium fan, circulating water cooling, 8-degree water cooling, water mist collector (Monsanto filter element), two-stage packed drying tower, bubble tray drying tower, acid mist collector (Monsanto filter element), turbine. The water content in chlorine is below 20 ppm (by volume). This post was last edited by limingshuguang on 2008-3-8 11:56.]
Hangzhou Zhonghao Technology Co., Ltd. possesses extensive experience in the domestic chlor-alkali industry, particularly in the design and manufacture of chlorine drying tower equipment. 1. The overall performance of its complete systems is among the best in China: the moisture content in chlorine can be kept below 100 ppm, the system pressure drop does not exceed 9 KPa, and the consumption of 98% acid is less than 20 Kg per ton of caustic soda. The system can operate reliably within a load range of 30% to 120%, with low operating costs. 2. The process design of the device is diverse, in order to meet the specific requirements of different customers. 3. The main tower in the unit features advanced design technology; it utilizes specialized, efficient internal components for the tower, resulting in high mass transfer efficiency, low energy consumption, as well as excellent and stable drying performance. 4. The tower units of the complete set are designed with appropriate materials, manufactured with high precision, offer high reliability, are easy to operate, and require virtually no maintenance.
