Ice blockage issue in the CO2 storage tank level gauge
Thread Content
Recently, the level gauge in the liquid storage tank of the workshop’s CO2 recovery system experienced ice blockage in the high-pressure side (i.e., the liquid phase side) piping. The level gauge in question is a Rosemount model. What measures should be taken if this situation occurs frequently? I wonder if anyone has encountered this situation? (The sampling pipelines are all insulated.)
Just using heat insulation isn’t effective; electric heating is needed. But this is just for making a table. In reality, it’s likely that there’s too much moisture, and there’s a problem with the dryer.:)
1. The medium is of course liquid CO2； 2. Thinking back to the recycling system, the moderator was right – before this, there was a high amount of moisture in the second stage of compression of the CO2 compressor, which caused compressor failures. As for how effective drying is when the compressed CO2 passes through the dryer, further observation is needed. Thank you to those up above for their attention and to the moderator for their reply
What is the ambient temperature? How long has this table been running? Check whether the heat tracing system is functioning properly. If the heat tracing is functioning properly and the designed insulation temperature is achieved, the moisture level will not change. Unless it turns into dry ice~~~~
It has been in operation for about 4 months without a heating system; the liquid phase sensor is insulated. When this situation occurs, washing the insulation around the liquid phase sensor with water can help resolve it. But the specific cause of the blockage is still under analysis. Do anyone have any good suggestions?
