Fcc feed nozzle
TīmeklisThe first generation of modern FCC feed nozzles was introduced in 1980,s [2]. The design was based on producing a high-velocity liquid jet and shattering liquid jet to droplet upon hitting the target and conveying the droplets with steam to nozzle exit. As a result, this nozzle requires high feed pressure and high steam usage to Tīmeklis2024. gada 7. febr. · Operating with 8 fluid catalytic cracking (FCC) feed nozzles which help convert hydrocarbons into lighter products, a Midwest U.S. refinery produces low-sulfur gasoline, gasoline blend stocks, ultra-low-sulfur jet fuel, petrochemical feedstock, and other byproducts.When one of the FCC feed nozzles became partially plugged, …
