How to quickly reduce the water content in the reaction system of new installations
Thread Content
The new plant has started operation, but the water content in the reaction system is above the specified level, preventing it from meeting the feed conditions. How can the water content in the reaction system of the new plant be reduced quickly?
The amounts of steam in various parts of the reaction system decrease (loosening steam, pre-raising steam, atomization steam, anti-coking steam)
The nitrogen is circulated in the reaction system; the electric heating furnace is used to raise the temperature to 150 degrees. Gas circulation continues within the reaction system, and high-pressure air cooling is applied. When no water is visible at the cold high-density interface, does that mean that all the water in the system has been removed? It’s just my personal opinion
Start the main fan for purging, use low-point venting, and employ nitrogen for purging.
It would be best to specify the exact device. I saw mentions of catalytic cracking units, as well as methods related to catalytic reforming units; but in my opinion, it’s a reforming unit! It’s probably caused by improper cyclic heating, and also by the high water content in the raw materials!
Pipelines should be in place for nitrogen water removal at the start of operation
Cycling nitrogen through the reaction system for heating and drying, followed by drying again after adding the catalyst, can effectively reduce the water content in the system
