Lecture 43: Slurry Reactor Design | …
Slurry Reactor Design; Course Description. In simple terms, stone Engineering deals with the production of a variety of chemicals on large scale. Large scale production is associated with the engineering problems such as fluid flow, heat and mass transfer, mixing and all types of unit operations. These chemicals are produced through stone reactions in a vessel called “Chemical Reactor ...
Slurry Reactor - an overview | ScienceDirect Topics
Slurry reactors were developed to overcome the difficulties associated with the fixed-bed multitubular reactors. 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 ].

The slurry Fischer-Tropsch reactor was, therefore, operated at low H {sub 2}/CO ratio on gas directly from a Shell gasifier. The fixed-bed reactor was operated on 2.0 H {sub 2}/CO ratio gas after adjustment by shift and CO {sub 2} removal.

Many industrial processes involve multi-phase systems, and perhaps the most complex is the gas-liquid-solid or slurry reactor. The complexity of this system arises from the simultaneous presence of mass and heat transport involving all three phases in addition to reaction.

Slurry reactors are three-phase reactors, meaning they can be used to react solids, liquids, and gases simultaneously. They usually consist of a catalyst (solid) suspended in a liquid, through which a gas is bubbled. They can operate in either semi-batch or continuous mode.
Reactor Design - an overview | ScienceDirect Topics
Nuclear reactor design is highly multidisciplinary. In each reactor, disciplines like fuel and material science, reactor physics, thermal hydraulics, and structural mechanics interact. This makes nuclear engineering one of the most demanding professions.

Design of slurry reactor for indirect liquefaction ...
A slurry reactor is defined here as a three-phase bubble column reactor using a fine catalyst particle suspension in a high molecular weight liquid. The feed gas is introduced through spargers. It then bubbles through the column providing the agitation necessary for catalyst suspension and mass transfer.

Bubble column reactor - Wikipedia
Since the computerized design of bubble columns is restricted to a few partial processes, experience in the choice of a particular type column still plays an important role. Literature. Bubble column reactors belong to the general class of multiphase reactors which consist of three main categories namely, the trickle bed reactor (fixed or packed bed), fluidized bed reactor, and the bubble ...
Mass transfer and hydrodynamics in catalytic slurry reactors
eration is of utmost importance for a proper design of catalytic slurry reactors, in terms of reactant conversion and product selectivity, where the reactor size is largely determined by mass transfer, and the selectivity of the reaction is strongly dependent on mixing time and residence time. The aim of this thesis is to understand the influence of catalyst particle properties and the ...

Theory • A Slurry reactor is a multiphase reactor system in which all the three phases i.e. Solids, Liquids and Gases can be reacted. • In the Slurry Reactors the two-phase or the three-phase catalytic reactions can be carried out. • In three –phase reactor, gas and liquid reactants are brought into contact with solid catalyst particles.
