What is the purpose of online oxygen content monitoring of the degasified gas in a atmospheric and vacuum distillation unit?
The negative pressure tower prevents air from leaking into the tower and causing an explosion
Prevent oxygen from entering the tower to form a mixed gas, which could burn or explode upon contact with a fire source
Prevent oxygen from accumulating in the tower and causing an explosion due to the high temperatures inside it
Prevent negative pressure oxygen; once the oxygen level exceeds the limit, reduce pressure and check for leaks
The pressure inside the vacuum tower is negative; if there are leaks, they are not easy to detect. When air enters the tower, fires and explosions can occur due to the high temperatures. Moreover, heavy oil contains a high level of sulfur, and in the presence of air, ferrous sulfide can ignite spontaneously. Monitoring oxygen levels is done primarily to detect leaks – if the oxygen level is too high, it is necessary to investigate for leaks promptly.
Prevent leaks in the vacuum tower, which could allow air to enter the tower and lead to fires or explosions
Dear experts, what is the value of this indicator?
The pressure inside the vacuum tower is negative; if there are leaks, they are not easy to detect. Air entering the tower can lead to fires and explosions due to the high temperatures. Monitoring oxygen levels is done primarily to prevent leaks in the tower and its vacuum systems. If the oxygen level becomes too high, it is necessary to investigate and address the leak promptly.
