Abstract:

In connection with the leakage problem of the return mixing tank stirrer during the production process of the 400 kt/a acetic acid unit, the nozzle of the return line is revamped after verification in all aspects and combined with the actual operation condition. After the revamp, the materials in the return mixing tank can be self-stirred, and the stirrer can be completely removed, which not only reduces the inspection and maintenance costs of the rotating machinery, but also eliminates potential safety hazards.
