WebIn FCC, a fluidized-bed (or fluid-bed) of catalyst particles is brought into contact with the gas oil feed along with injected steam at the entrance (called the riser) of the reactor. The hot catalyst particles coming from the regenerator unit evaporate the feed gas oil upon contact in the riser, and the cracking starts as the gas oil vapors ... WebRefinery offgases, typically from fluid catalytic cracker units and coker units, are normally disposed of as feed into the refinery’s fuel gas system. However, these streams contain significant amounts of olefins which can be economically recovered and/or converted. In fact, many of the projects have simple payout times of less than two years. fazer brainhow
