Atomization of CO2 Extracts Atomization occurs when a jet of liquid is broken down into more or less fine droplets. The ideal spray consists of drops of the same diameter. There are different technologies to obtain a micronized powder with CO2. The best known are: NEA (Near-critical Expansion … [Read more...] about Atomization of CO2 Extracts

Near-critical Expansion Atomization In NEA (Near-critical Expansion Atomization) process, the carbon dioxide is used in this process for the atomization and the crystallization of the product. The product subjected to the process is maintained in the liquid phase … [Read more...] about Near-critical Expansion Atomization

Rapid Expansion of Supercritical Solution RESS (Rapid Expansion of Supercritical Solution) is used generally to produce fine particles for the food, cosmetic and pharmaceutical industry.Organic material is dissolved in supercritical carbon dioxide and is used to … [Read more...] about Rapid Expansion of Supercritical Solution

Particles from Gas Saturated Solutions PGSS (Particles from Gas Saturated Solutions) is a technique for the production of microparticles of different materials of relatively low melting temperatures, such as polymers, waxes or fats. The process is based on the … [Read more...] about Particles from Gas Saturated Solutions

Supercritical AntiSolvent Micronization As mentioned previously, the low solubility of a part of pharmaceutical products of interest limits the use of SC-CO2 as a solvent in the mico or nano production of particels. To solve this problem it was decided to use the SC-CO2 as anti-solvent … [Read more...] about Supercritical AntiSolvent Micronization

Supercritical Assisted Atomization SAA (Supercritical Assisted Atomization) process is focused on the nebulization of the liquid solution rather than using dense gas (SCF) to achieve precipitation by solubility reduction for the solute to be micro- or nano-sized. … [Read more...] about Supercritical Assisted Atomization
