【Daily Question 2019】Hydrogen production and hydrogenation section – Question No. 024: Briefly describe the main tasks involved in the maintenance of ordinary towers. Reference: The tasks involved in tower maintenance include cleaning the inner walls of the tower as well as internal components such as trays. Inspect and repair corrosion, deformation, and welds in the tower body and lining. Inspect, repair, or replace the tray plates and bubble elements. Inspect, repair, or replace the components inside the tower. Inspect and repair components such as the foam breaker screen, oil tank, spraying device, and demister. Check the safety accessories for verification. Inspect and repair cracks, damage, tilting, and settlement of the tower foundation. Inspect and repair the tower’s paint and insulation. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

1. Remove the manhole to enable natural ventilation for cooling, and take samples to analyze whether the oxygen content is within acceptable limits； 2. Conduct a visual inspection to check whether there is any reverse flushing or detachment of the trays at each manhole, and whether there are any sediments or foreign objects at the bottom of the tower ； 3. Disassemble the tray assembly and check, from top to bottom, the free movement of the floating valves on each tray layer, as well as whether there are any foreign substances such as sediment in the liquid drop pipes of each layer ； 4. Check whether the extraction ports and return ports on the walls of each tower are unobstructed and free of any foreign objects ； 5. Check for corrosion in areas such as the tower walls, trays, downcomers, and extraction port short circuits
