What is the impact of the steam amount atomized by the nozzle on the cracking of the feedstock?
Thread Content
What are the methods available to adjust the reaction severity as the viscosity of the raw materials changes? Can changing the amount of steam atomized by the nozzle optimize the cracking of the feedstock and improve the product distribution? I hope everyone will actively participate in the discussion!
Personally, I think this topic has been discussed extensively by many experts on forums; generally, the amount of vaporized steam accounts for 5-8% of the feed volume. Superheated steam at 1.0 Mpa is most commonly used, while some systems employ dry gas at the same pressure level； The specific application is generally determined based on various factors such as the product yield distribution, the distribution of catalyst fines, and the density of raw materials, rather than through a simple one-to-one adjustment. In terms of operation, there is always only the most appropriate value; it is a dynamic value rather than a fixed one, and we need to explore the relevant patterns through our work.
