Regarding the tower issue, please help out
Thread Content
Our company is located in Gansu and mainly produces phosphorus pentachloride. When producing phosphorus trichloride, we need to heat the reaction reactor to around 80–83°C, with a pressure in the reactor of less than 10 kPa. The temperature in the phosphorus washing tower is between 76–77°C, and the pressure in that tower is around 3 kPa. At present, we are able to raise the pressure in the reactor to around 82°C, but the pressure in the tower can only be raised to around 69°C. We have tried many methods, but the temperature in the tower just won’t go up. I hope everyone can help me come up with a solution
Continuous heating should be able to raise the temperature, so where does the heat go? Help boost the post with friends{:9001:},
The temperature changes in equipment such as towers are related to the flow of fluids. It is advisable to check whether the operation of the fluid flow process is reasonable and whether there are any issues with the instruments, for reference.
Pressure, temperature, and composition are the three key factors in tower operation; if the temperature rises while pressure does not, it is related to the composition
First of all, the temperature needs to be increased before chlorine is introduced. The temperature of the reactor, the pressure in the reactor, and the pressure in the tower are all within the normal range for the process; only the temperature of the tower fails to rise. I’ve adjusted the amount of condensation as well as the reflux rate, and I’m wondering if it might be related to atmospheric pressure
The top temperature is not a key control parameter; what matters most is whether the phosphorus trichloride obtained through distillation meets the required standards. If the product quality is up to standard, there’s no need to worry about the top temperature!
Yes, you’re right; that’s exactly what was done the night before last. After sampling and analysis, the concentration met the requirements for first-class quality at 98.5%. We plan to make some adjustments today and take samples for further testing
Determine whether the tower pressure measurement is incorrect, and whether the steam flow rate is consistent with the design value
I can provide you with packaging equipment for phosphorus pentachloride; I have relevant experience in this area
