What is an appropriate value for controlling the temperature of the transformed stripping off-gas?
Thread Content
The stripping gas at the top of the transformed condensate stripper is usually cooled before being sent for sulfur recovery or to a flare. Since this gas contains hydrogen sulfide, carbon dioxide, and ammonia, improper temperature control can lead to crystallization and pipe blockages. What is an appropriate temperature range for control in actual production?
It is generally around 95°C; this value is mainly adjusted based on the ammonia nitrogen content in the system
We maintain the temperature between 65 and 95°C; if the stripping pipeline is equipped with heating, it is ensured that this heating is in use, and the control is primarily based on the ammonia nitrogen content in the condensate coming out of the stripping tower. Finding the right temperature – of course, the higher the better – increases steam consumption and also exacerbates thermal stress corrosion in the pipes.
