What is Bubble Cap Raiser?
A bubble cap raiser is a vertical pipe used in fluidized catalytic cracking (FCC) units, typically found in chemical engineering and petroleum refining processes. It connects the reactor vessel with the regenerator vessel and facilitates the movement of catalyst particles and hydrocarbon feedstock between them. The raiser is equipped with mushroom-shaped bubble caps evenly distributed along its length. These caps help distribute the feedstock uniformly across the catalyst bed and create a bubbling action by allowing gas or steam to flow through them. The bubbling promotes efficient mixing and contact between the catalyst and feedstock, enabling the conversion of heavy hydrocarbons into lighter, more valuable products.
Types of Bubble Cap Raisers
Fixed Bubble Cap Raiser
This type of raiser has bubble caps that are permanently fixed or welded to the raiser pipe. The caps are evenly distributed along the length of the raiser and provide consistent bubbling and distribution of the feedstock and gas.
Removable Bubble Cap Raiser
In this design, the bubble caps are not permanently fixed to the raiser. They can be removed for maintenance or replacement purposes. This type allows for easier access to the raiser internals, but it may require additional steps to ensure proper sealing when the caps are reinstalled.
Instead of bubble caps, slotted raisers have slots or openings along their length. These slots allow the gas or steam to escape and create the desired bubbling effect. Slotted raisers are often used in situations where bubble caps may not be practical or efficient.
Multi-Stage Bubble Cap Raiser
In certain processes, multiple stages of cracking or reactions may be required. Multi-stage bubble cap raisers have several sections or levels, each with its own set of bubble caps. This design allows for more controlled reactions and better separation of different products.
Dual Feed Bubble Cap Raiser
This type of raiser is used when two different feedstocks or catalysts need to be introduced into the process. It has separate inlets for each feedstock, and the bubble caps are designed to ensure proper mixing and distribution of both streams.
Key features of Bubble Cap Raisers
Bubble cap raisers are specifically designed for fluidized catalytic cracking (FCC) processes. They provide a conduit for the catalyst particles and feedstock to move between the reactor and regenerator vessels, where the cracking reactions take place. The raiser’s design facilitates the necessary high temperatures and residence times required for the cracking process.
Bubble cap raisers can be designed to be fixed or removable. Removable bubble cap raisers allow for easier maintenance and replacement of bubble caps, ensuring the optimal performance of the raiser over time.
In some applications, multiple stages of cracking may be required. Bubble cap raisers can be designed with multiple sections or levels, each with its own set of bubble caps. This enables the process to be divided into distinct stages, improving control and separation of different products.
Dual Feed Capability
Certain processes may require the introduction of multiple feedstocks or catalysts. Bubble cap raisers can be designed with separate inlets for each feedstock, allowing for the simultaneous processing of different streams. The bubble caps ensure effective mixing and distribution of both feedstocks.

The bubble cap raiser is used in fluidized catalytic cracking (FCC) processes to transport catalyst particles and hydrocarbon feedstock between the reactor and regenerator vessels. It facilitates the cracking reactions by distributing the feedstock evenly and creating a bubbling action for efficient mixing with the catalyst.
The bubble cap raiser operates by allowing gas or steam to flow through the bubble caps installed along its length. This generates a bubbling action that enhances the contact and mixing between the catalyst and the hydrocarbon feedstock. The rising mixture of catalyst and feedstock undergoes cracking reactions as it passes through the riser.
Bubble cap raisers offer several advantages. They ensure uniform distribution of the feedstock, promote efficient mixing, and enhance the contact between the catalyst and feedstock, leading to improved cracking reactions. The design of the riser allows for flexibility, maintenance, and replacement of bubble caps as needed.
Yes, there are different types of bubble cap raisers. They can be fixed or removable, have slotted openings instead of bubble caps, or be designed with multiple stages for specific process requirements. Some bubble cap raisers are also designed to handle dual feedstocks or catalysts simultaneously. Know more
