Back Flush Oil Recycle

Back Flush Oil Recycle

As you known, Back Flush Oil also is injected to riser with its important role. When I studied in my university, I always confused about its role which will be mentioned in this post.

RFCC Back Flush Oil

Where do back flush oil come from ?

Back Flush Oil comes from Slurry Separator in which separates fine catalysts in Slurry oil. Slurry Separator has many electrical plates…

The Role of MTC Recycle in RFCC

MTC Recycle ( Mix Feed Temperature Control) is used as an innovative development of RFCC technology. At the first of time, MTC is only used in Riser ( Reactor Section of RFCC ) to control reactions which happen more advantageously at high temperature, low pressure comdion. But, in mordern technology, MTC not only use in Riser but also in mixing with Feed to control…

The role of Steam in RFCC

THE ROLE OF STEAM IN RFCC

Steam plays important role in RFCC unit, not only increases atomization of feed but also keeps stabilization. This post will mention about the role of steam in RFCC, especially, in the Reaction and Regenerator

In the Reactor, the reaction between hot catalyst with feed is happened mainly in riser during two seconds (Depend on the technology). On the riser, we can see…

RFCC Overview – Feed Preheat Section

RFCC Overview – Feed Preheat Section Feed Preheat Section

In RFCC unit, Feed preheat section where receives feed from Feed tank is exchanged heat with some heat exchanger to increase the feed temperature to requirement before sending to Reaction section. In this post, I will explain heat preheat section included : Feed Surge Drum, Feed Pump and Heat Exchanger system.

  Feed preheat section

RFCC HANDBOOK COLLECTION

RFCC (Residual Fluidization Catalyst Cracking) is the most important unit in Petroleum Refinery where converts residue to more valuable products such as gasoline, Light Cycle Oil… Therefore, It is necessary to understand clearly about this process.

Today, I collected some RFCC e-books which will summarize in this post. If you need any e-books, please give me email…

WATER HAMMER and STEAM HAMMER ( part 1)

WATER HAMMER AND STEAM HAMMER

Water hammer and Steam Hammer are most common phenomenon in Petrochemical Industry, especially in steam line, water line (Boiler feed water, Demineralized Water)

This topic which provides more knowledge about two matters is collected from many sources, which will help you understand clearly and distinguish the difference between steam hammer and water hammer

Water…

After Burning and Behind Burning

After Burning and Behind Burning

In RFCC process, after burning and behind burning are some problems that can happen in during start up, shut down or nomarl operation. Today, in this discussion, i will mention this matter, especially about How to recognize it, How to fix it and its consequence

Firstly, i want to mention some…
