from the high-pressure vessel to the first reactor. The equilibrium catalyst is withdrawn from
the third reactor and transported as slurry to the second reactor. The spent catalysts are
withdrawn from the first and second reactors to the transfer vessel. It is then washed, cooled
and transferred to the spent catalyst inventory vessel. Further utilization of spent catalysts from
