Accelerated Solvent Extraction for Additives in Polymer

The accelerated solvent extraction technique improves the extraction efficiency of plasticizers from polymers by using elevated temperature and pressure. Many of the organic solvents used in these extractions boil at relatively low temperatures at atmospheric pressure (e.g., acetone boils at 56 C). Get price

Solvent Extraction

Solvent Extraction Plants are used to extract oil by using chemicals. These plants use cake as the raw material, which is obtained from the oil press section. An organic solvent is used to dissolve the cake's or seed's oil content after the process of dipping or spraying, which ensures that the oil content is in close contact with the feeding material. Get price

Enhanced Solvent Extraction

Using a compressed water and carbon dioxide extraction system allows for the extraction of polar substances. The role of carbon dioxide is to permeate matrices, assisting water's solvent action. The Hightech Extraction System, when used to experiment with green coffee, allowed the complete decaffeination and the total recovery of caffeine from the separators. Get price

The Complete Guide to Hydrocarbon Extraction [New in

Solid-liquid Extraction Using a Closed-loop Extraction System Closed-loop extractors improve process efficiency when low-boiling point solvents are used for extraction. These types of extractors can extract the target compound(s) from a solid or liquid and recover most of the solvent so that it may be used again without exposing the system to the surroundings during the process.
