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 Sinnott, 2013).
The extraction of a solute from a solid matrix involves a three-stage process: desorption of the solutes and solubilisation in the solvent, internal diffusion through the solid phase towards the surface and external solute diffusion in the liquid volume . Extraction can be performed using fresh/dried and ground/whole samples.
Solid-liquid extraction was utilized to separate the carbohydrate components from lignocellulose, leaving lignin behind. The lignin was then used for further fermentation experiments. Solid-liquid extraction can also be used to measure the wax content in fruit skins. In this experiment, the wax content of tomato skins was analyzed.
Liquid-Liquid Extraction – Acetic Acid. Biofuels and chemicals produced by biological processes such as fermentation and algae often require liquid-liquid extraction (LLE) as the first step in recovery and purification. Many of these chemicals are higher boiling than water or form azeotropes, resulting in high energy requirement for distillation.

Solid–liquid extraction was carried out in a Soxhlet apparatus with pulverized lime waste at 68 °C for 180 min; then the residue was washed and aerated. From the pre-treatment procedure, 21.3 mL of essential oil was recovered, indicating an oil yield of 3.8%. . the reactors were flushed with a gas containing 80% N 2 and 20% CO 2 to ensure .
Solid/Liquid extraction process is a very common process in the pharmaceutical, cosmetic and food industries to obtain natural ingredients as flavors and fragrances from natural raw material. The extraction can be carried out with hot or cold solvents.
Operation - Solid-Liquid Extraction: The solid to be extracted is put inside a glass fiber bag and placed in an extraction vessel. Solvent from the reboiler is continuously evaporated,condensed and circulated through a reflux divider by means of piping network and valves.
Since the material leaving the reactor is a gas-liquid-solid mixture, a vacuum degasifier is required to separate the gas and avoid floating sludge in the clarifier. Fluidized Bed. This reactor consists of a sand bed on which the biomass is grown. Since the sand particles are small, a very large biomass can be developed in a small volume of .
