The first slurry reactor was commissioned by SASOL in 1993, with a diameter of 5 m and a height of 22 m (Figure 12-16) [48]. In 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]. Compared to the fixed-bed multitubular reactor, the slurry reactor is much easier to design ...

Slurry reactors are most frequently used when a liquid reactant must be contacted with a solid catalyst, and when a reaction has a high heat of reaction. They may be used in such applications as hydrogenation, oxidation, hydroformation, and ethynylation. The reactor shown below is a slurry phase hydrogenation reactor.

The feedstock may require pretreatment to reduce the particle size and/or to remove contaminants such as stone, metal, or plastic. The uniform feed is fed into the hydrothermal reactor where it is processed typically for several hours depending on the reactor design. The slurry is then typically mechanically dewatered and dried.

Slurry Reactors. Since slurry reactors already use a mix of solid catalyst and liquid reactants, any of the methods described in the Stirred Tank Reactors section can be applied to slurry reactors. It is not recommended to use internal coils in such a design, as reactor slurry will often corrode heat exchange material very easily (Towler and ...

Abstract. Slurry reactors are applied nowadays in a wide range of chemical processes, both on a laboratory scale and in industrial practice. Applications range from catalytic hydrogenation of edible oils, coal hydrogenation, Fischer- Tropsch reactions to biological reactors (e.g. single cell proteins) and polymerization reactors.

Conditions in the unmodified reactors, and particularly in the first reactor, were conducive to attrition. After modification, the DI of the reactor 3 discharge solids was 3.7 and indicated a substantial decrease in attrition due to the baffling, the redesigned impellers, and the subsurface discharge of slurry from the reactor.

One key advantage of using a fluidized bed reactor is the ability to achieve a highly uniform temperature in the reactor. Slurry reactors. A slurry reactor contains the catalyst in a powdered or granular form. This reactor is typically used when one reactant is a gas and the

The principles of good slurry pipeline design, suspension, and handling have been well defined since the early 1950s. However there have been significant refinements to detailed hydraulic design. In most cases the strategy is to make a settling slurry into a non-settling slurry so that it can be treated as a normal, homogeneous fluid.
