Slurry Reactor - an overview ScienceDirect Topics

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 ...

The objective of these studies was to perform a realistic evaluation of the relative costs of tublar-fixed-bed and slurry reactors for methanol, mixed alcohols and Fischer-Tropsch syntheses under conditions where they would realistically be expected to operate. The slurry Fischer-Tropsch reactor was, therefore, operated at low H{sub 2}/CO ratio on gas directly from a Shell gasifier.

Slurry - Visual Encyclopedia of Chemical Engineering

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.

Slurry Reactors – SLI Process

Features. Operate in continuous or semi batch mode. The unit can be integrated with a microreactor and the outlet of the slurry reactor can act as an input feed to the microreactor. High surface area to volume ratio can be used for better heat and mass transfer. The unit is capable of rotating the mass at around ~ 4000 RPM. Applications.

Feb 22, 2016  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 ...

Slurry reactor - SlideShare

Mar 13, 2014  Slurry reactor. 3. Any mixture of solid liquid or a gas gas is called slurry. Sloppy mud, cement or mixture of additives in petrochemicals. 4. Slurry reactors are three-phase reactors, meaning they can be used to react solids, liquids, and gases simultaneously. They usually consist of a solids suspended in a liquid, through which a gas is bubbled.

Then slurry is pumped through a simple spray head inside the reactor and into a fluidized-bed drying zo There, the slurry vehicle is vaporized, leaving the dry coal available for feed into the lower stages of the reactor. The vaporized slurry oil exits with the raw gas stream out of the top of the reactor.

hydrodynamics of a slurry bubble column reactor operating in the churn-turbulent regime is pictured in Fig. 1. The churn-turbulent regime of operation is the most optimal one for F–T synthesis [1]. One of the most important parameters to be estimated for slurry reactor design and scale-up is the holdup of gas bubbles in the reactor, .
