Treatment capacity of chlorine gas leak absorption tower

Thread Content

I humbly ask the teachers a few questions.:lol I don’t know if the tiger is still there 1. How to calculate the chlorine emission from the entire system to the tail-suction system after a trip occurs while a chlor-alkali plant is operating at full capacity? 2. How to calculate the treatment capacity of an absorption tower based on chlorine emissions? What are the specific requirements for the absorption tower? For example, what duration must be ensured for emergency chlorine release? 3. Taking a 100,000-ton chlor-alkali production plant as an example, how is the leakage amount and absorption amount of chlorine calculated? 4. Are there any other methods available to deal with emergency releases of chlorine, in addition to the tail-suction absorption tower system? For example, could storage tanks be used to temporarily capture the highly pure chlorine gas emitted, and once operations stabilize again, this chlorine gas be fed into the inlet of the turbine for use? Or install a backup power supply for the refrigeration compressor, so that it can continue to liquefy the remaining chlorine gas when the system is shut down? If the amount of chlorine is high, how can we make full use of it during the short period when the system is shut down? 5. How to calculate the processing capacity of a drying system? Is there any evidence? The ultimate goal is to remove moisture from chlorine gas; what mechanisms within the drying system are used to achieve this? How are the processing capacities and size selections for each drying tower and catcher determined? Why use a dryer of such a large size? Why does a water mist collector use 6 filter elements instead of 4, and how is this determined? 6. How is the power generation capacity of a turbine calculated? The process requirements specify that the inlet pressure of the turbine should be at a certain level (for example, -5 kPa) while the outlet pressure should be 0.4 MPa. How should three-stage and four-stage compression be chosen? Why increase the speed of the turbine or the size of the impeller? What are the bases, advantages, and disadvantages? 7. Should the height of the circulating water return pipeline be considered for the horizontal shell-and-tube chlorine cooler in the turbine system? For example: a certain small turbine is equipped with two chlorine coolers. If the return water pipeline uses pressure-free return water, could lowering it below the level of the two coolers cause the water flow to take a short circuit within the coolers (resulting in insufficient flow through the tubes)? Is it necessary to raise the height of the cooler outlet pipe line above the cooler? 8. How can the salt crystallization of sodium hypochlorite in the tail suction tower be improved? Should the concentration of liquid caustic be reduced, or should the filler be replaced? How is the amount of filler determined?
