Several issues in polypropylene loop pipe technology
Thread Content
I recently read the introduction of ring pipe polypropylene and I have many questions that I don’t understand. Please answer 1) Why does TEAL need to design a metering tank after setting up a D-111 storage tank? Does the measuring tank have any other functions?
Industrial design is sometimes more accurate
Although it is not clear, this technology is generally mature
Polypropylene triethylaluminum is generally purchased from outside and packed in cylinders. The D-111 storage tank can hold one cylinder of TEAL after replacing it with a new cylinder. The setting of the metering tank is mainly to calibrate the mass flow meter at the outlet of the metering pump.
Is the outlet a mass flow meter? Other processes generally do not have this metering tank, and the TEA area always feels that there are more leakage points and the risk increases.
It is a mass flow meter. During the pouring process from the TEAL cylinder to the storage tank, leakage is most likely to occur. If there is a slight leak, only the cylinder and storage tank can be isolated by interlocking. In order to maintain continuous production. 5 independent partitions are set up. It is assumed that if a metering tank is not designed and a slight leak occurs and a fire occurs, safe production cannot be guaranteed.
This may be a question of design concept. What do you mean by the five safe partitions you mentioned? In addition, I think that the pipeline from the metering tank to the pump should be led from the bottom of the tank and placed on the top of the tank in case the flange leaks. . . Anyway, all the other pipelines in that tank are at the top, so this pipeline is not bad either.
The cement wall is divided into 5 safety areas, each with independent dry powder fire extinguishing alarm and activation systems. As for the pipeline that goes to the pump from the metering tank leads from the top of the tank, are you kidding me? Cylinders are most likely to leak into TEAL storage tanks because of the disassembly and assembly of flange surfaces and frequent switching of processes.
Of course, it’s usually not that easy to leak if you don’t disassemble it, but I don’t think there’s any problem with it being led from the top. Can you tell me what you think is inappropriate?
The TEAL metering tank is just a storage tank protected by micro-positive pressure nitrogen.
Why lead it from above, then pump it, and measure it like this. I don't understand what the original poster meant. @What this guy said on the 16th is spot on.
