What is the cause of the total blockage in the triethylaluminum pipeline?

Thread Content

I’m working with process piping; after the major repair, there was blockage in the triethylaluminum pipelines. Two pipelines had to be replaced in total. Is there anyone who can help me analyze the cause?

Has the composition of the blockage been analyzed? According to information available online, triethylaluminum is a liquid at room temperature and does not solidify; it seems that other substances were formed as a result of a reaction, and this reaction should be avoided

It’s stuck in that section; if it’s near D201, it’s possible that impurities from the donor have diffused into the TEAL pipeline
