The current installation of chlorine engineering requires a fan, and Asahi Kasei's zero-pole distance electrolyzer requires a fan. Most of the drying systems are fiberglass or +PVC equipment that cannot withstand negative pressure, so positive pressure operation will be safer.
Positive pressure ensures the purity of chlorine.
1. The choice of pressure should be related to the choice of process: Diaphragm OR ion membrane ； 2. Generally, diaphragms are produced using negative pressure and transported by Nessler pumps or other forms of liquid ring pumps, which consume large amounts of power, are difficult to detect leaks, and produce waste sulfuric acid. ； 3. Generally, ion membranes are produced using positive pressure and transported by turbines, which are energy-saving, environmentally friendly, and require large investment. ； 4. There is also a process of using a turbine in the diaphragm system. In this case, a titanium blower is required to pump out chlorine gas to increase the pressure, and then enters the turbine. ； 5. Both processes have applications. We are a positive pressure and a negative pressure: Classic craftsmanship. :lol
After using a titanium chlorine blower, positive pressure operation is helpful to ensure the purity and moisture content of chlorine.； But if you have both a separator and an ion membrane, you need to pay attention to the balance.
Is positive pressure more likely to leak?
No problem, as long as the pipeline material, construction quality, careful operation, etc. are done well, there will be no leakage of chlorine. The advantage of positive pressure is that the purity of chlorine is high, which helps to improve the subsequent liquefaction efficiency.； In addition, the positive pressure is not very high, so the impact is not big!
