What should be the water content of crude oil in a catalytic cracking unit?
This post was last edited by LQ198619 on 2017-1-12 05:19. Trace levels of water in catalytic raw materials are required; it is extremely dangerous for catalytic device materials to contain water.
Is some water also removed through electrodialysis? What are your metrics?
Electrodesalination removes the water from the bitumen feed; it has absolutely no impact on the water content in the raw materials used in the catalytic unit!
What’s the danger? Learn* it a bit.
Our value is generally below 0.03%; the presence of water can cause fluctuations in the preheating temperature, as well as in the reaction temperature and pressure. In severe cases, the raw material pump may get emptied, which affects feeding and may require stopping the process.
Traces of water are a problem; if the raw material contains excessive water, it affects the reaction pressure, which in turn impacts the feeding to the lift pipe. Fluctuations in feeding can cause changes in the operation of the cyclone separator inside the settler, potentially leading to coking there, which is very problematic
Don’t talk nonsense; the catalytic charged desalination method we use here is indeed related to electrodesalination!
