2 Fluid Catalytic Cracking Fluidized Catalytic Cracking is a process used in petroleum refining for production of petrol, diesel, naphtha, ATF and LPG. The process utilizes a microspherical zeolitic catalyst which fluidizes when it comes in contact with heated crude oil resulting in conversion highboiling petroleum fractions to more useful products. The process is carried out in a unit called Fluid Catalytic Cracking Units (FCCU), consisting of four sub-systems named as riser reactor, stripper, disengager and regenerator.
3 Why Radiotracer Investigations? The efficiency and quality of the products produced in a FCCU depends upon flow parameters such as residence times, velocities, slip factor, axial and radial mixing of the flowing phases. A radiotracer investigation was carried in an industrial FCCU in a refinery in INDIA to measure the various flow parameters before revamping, stepping up the production and modification of design of some of the components.
