Have you ever Visited a Refinery?
This Video is a must for Interviews in any Petroleum or Petrochemical Industry.
#Summary and #Highlights
To have a detailed chat and one to one consultation with me, you can book an event on my Calendar 📅 as per your requirement, on this link: engineeredlearnings.dayschedu...
The Heavy Oil (The Feed to a FCC Unit) is preheated and pumped into the riser wherein dwells the hot catalyst which first converts the liquid Oil into Vapour and then the Vapour undergoes cracking to form cracked products.
In the process of cracking, The formation of some heavy deposits of Carbon leads to the deactivation of the catalyst by blocking its pores.
The Reactor Holds the Cyclone Separators in series for the separation of the spent catalyst from the cracked vapour products of cracking.
The cracked vapour products are then send to a distillation unit which leads to the extraction of several lower useful cuts resulted from cracking of the heavy oil, the top product being C1 - C4 and the bottoms being Slurry oil which is recycled to the Feed of the Unit.
The Spent Catalyst is send to the Regenerator which burns off the Carbon deposited by the supply of excess Air and the Regenerated Catalyst is send back to the riser at a high temperature which creates the perfect ambiance for further cracking of the new incoming Feed.
#Note: ENGINEERED LEARNINGS has been created as an effort to reach out to All The Engineers (Students, Professionals and Aspirants) with the Basic Understanding of The Topics important for Placements, Interviews, Vivas, Semesters and Competitive Examinations.
