Hi everyone,
I am doing my final project for my master degree, it is about a steam reforming plant that uses natural gas as a feedstock and i have a doubt.
I have read that the fact of preheating the feed before the inlet of the reformer tube would improve the gas synthesis, furthermore, the furnace would need less fuel in order to achieve the final temperature.
Let's suppose that the feed current has high content in methane because it is natural gas and there is a prerreforming unit before the reformer.
My question is, has the increase of the inlet temperature any high limit?
I have read about the carbon deposition but i am not able to understand the phenomenon, so, if the feed currently enters at 650 ºC, would it be a problem if we heated the feed upper to 650ºC ? Would it appear carbon deposition if we did it?
Thank you so much!
