What is the replacement cycle for the packing in a vacuum distillation tower?
Thread Content
When processing high-sulfur crude oil with a sulfur content of 2.5% and an acid number of 0.3, 304L material is used as the packing in the vacuum section – does it need to be replaced after 3 cycles? How often should it be replaced under normal operation?
The specific replacement time should be determined based on the actual operating parameters, rather than following a fixed schedule; replacement is not necessary if the heat transfer capacity meets the requirements
Check the corrosion; if it is severe, it needs to be replaced.
Take it apart during maintenance to check the situation
Based on the inspection results, it is possible to prepare the materials; a replacement is not necessarily required
