Problems with the Wu Leng chlorine liquefaction unit
Thread Content
I would like to ask everyone about the relationship between inhalation pressure and inhalation temperature； Are the suction temperature and evaporation temperature the same? (The manufacturer says they don’t differ much, but what exactly is the difference? Is there a specific value?) In our factory’s liquefaction unit, when the suction pressure is 0.12, the suction temperature is -17 degrees ； At an intake pressure of 0.17, the intake temperature is -12 degrees, resulting in a decrease in liquefaction efficiency.
No one has replied for over a month; I’ll share my thoughts. Please be understanding regarding right and wrong! A high intake pressure results in a high intake temperature, while a low intake temperature leads to a low intake pressure (but this isn’t absolute!) I wonder if your crew keeps records of temperature and pressure under the same chlorine pressure and flow rate? Under the same conditions of chlorine gas, it’s still possible to assess the liquefaction effect. Do you mean that 0.12 MPa and 0.17 MPa refer to situations with different amounts of chlorine gas and different liquid supply rates? The amount of chlorine that can be liquefied at 0.17 MPa is higher, while it is lower at 0.12 MPa. The suction temperature and the evaporation temperature can be considered equivalent in principle; in practice, the difference between them is not significant
Temperature increases as pressure rises. One pressure corresponds to one temperature. Changes in weather also have an impact on temperature. If the amount of Freon supplied is low, the amount of liquidification will also be small; won’t that result in high pressure and high temperature? The liquefaction efficiency is low; temperature and pressure vary significantly depending on the amount of chlorine, as well as the purity of the chlorine and residual chlorine.
