This study presented the replacement valve as a regulator of the catalyst's distribution from the Regenerator to the Riser in a pilot-scale fluid catalytic cracking (FCC). On a large scale, FCC applies Slide valves/plug valves as a regulator of the catalyst rate from the Regenerator to the Riser and removes nitrogen. Therefore it does not go to the Riser. However, on a pilot plant scale, it is not possible because of the pipe's small diameter so that the catalyst often gets stuck in the valve. Moreover, nitrogen often escapes to the Riser. This valve replacement is chiffon or layered U-shaped pipe by flowing the air below to regulate the Riser's distribution. This study uses the CFD approach, specifically the MMPIC and DEM models, including the preliminary validation with catalyst dimension based on the Geldart group A and A 'Miyauchi.
