In this paper, hydrodynamics of a multiphase spinning disc reactor has been studied using Computational Fluid Dynamics (CFD) simulations. The objective of this study is to understand and develop a compact spinning disc reactor with good mass transfer characteristics for multiphase gas to liquid applications such as Fischer Tropsch (FT). Reaction kinetics suggests that to achieve a high mass transfer rate, the goal is to have good gas distribution throughout the reactor with a large interfacial surface area between gas phase and the liquid hydrocarbon media (Krishna et al., 1995). Furthermore, FT reactions are highly exothermic and the major contributor towards the weight of the reactor is the cooling coils. A continuously operated spinning disc reactor can provide several advantages over conventional multiphase reactor with reduced reactor volumes.

The spinning disc technology uses the centrifugal accelerations to create thin highly sheared films on rotating surfaces (see Figure.1). Various studies carried out have indicated that the fluid dynamics within these films result in significant enhancement in mass transfer rates (Jachuck and Ramshaw 1994; Bodhoo and Jachuck 2000). It is therefore expected that a reactor based on this technology should allow rapid mixing in the liquid film, short liquid residence time, and rapid and rapid liquid/vapour heat/mass transfer. This makes spinning disc reactors strong contenders for performing fast exothermic reactions and reactions which are limited by mass transfer rates. A typical example for the mass transfer limited reaction is the Fischer Tropsch reaction. Also spinning disc reactors operate in a continuous mode and markedly reduce the inventory of hazardous chemicals, they could play an important role in improving the intrinsic safety of the plant.

SUPERCRITICAL CO2 EXTRACTOR FOR SALE: 5L, 10L and 20L - 2,000 psi Complete Supercritical Fluid Extraction System - closed loop. Our systems are made at our fabrication shop in the state of Washington. Systems available: 5L, 10L, 20L, 100L, and larger custom. Typical build time is 2 weeks. This is not a Apeks Supercritical or Waters Supercritical CO2 Fluid Extraction System. We believe it is a better system, since we use 1/2 inch tubing for the CO2 flow, which is 4 times the flow rate of a Apeks, and up to 64 times the flow rate of a Waters system. We believe the result is faster processing time and better yield from increased exposure to CO2 solvent. Perfect for extraction of terpenes, trichomes, and Cannabinoids. Supercritical CO2 Fluid Extraction is a art, and the operator must have experience and training to obtain results. Go to website
