Slurry Reactor

Slurry reactors were developed to overcome the difficulties associated with the fixed-bed multitubular reactors. The first slurry reactor was commissioned by in 1993, with a diameter of 5 m and a height of 22 m (Figure 12-16) [48] 1990, at Exxon, LA, a 1.2 m diameter, 21 m high slurry reactor with a production capacity of 200 bbl/day was developed [109].
