Temperature of raw oil for catalytic start-up
Thread Content
What temperature do you set for the feed oil used to initiate catalytic operation? What’s your setting? We raise it to the highest possible temperature, usually around 230 degrees
Here, we keep it around 200. Is your control set at the maximum level to prevent water from entering, or to reduce the temperature difference between the agent and oil?
We increase the height to reduce coking during reactive fuel injection
That is to reduce the temperature difference between the agent and the oil!
We feed the crude oil when its temperature rises to 200°C: lol
Is this effective for controlling coking?
With steam reverse heating, the temperature cannot get very high; it doesn’t reach 200, but is usually around 230.
Theoretically it works, but in practice the difference isn’t very noticeable; it seems the critical value hasn’t been reached!
Does the poster use a steam generator to heat the crude oil for production? 1.0 or 3.5 MPa?
We use a steam generator to generate 3.5Mpa steam in reverse flow
