Device for transforming chemical structures in a fluid comprising a solvent and salts by ultrasonic action

A system for producing the conversion of at least one chemical structure present in a fluid under pressure and at temperature, wherein said fluid comprises a solvent and at least one salt, said system comprises a vertical reactor comprising a first lower zone in which the fluid is maintained under first conditions of temperature and pressure ensuring high solubility of the salt or salts, and a second upper zone in which said fluid is maintained under second conditions of temperature and pressure leading to a precipitation of the salt or salts;

• wherein
• said vertical reactor further comprises means for controlling a first temperature condition of said first lower zone, means for controlling a first pressure condition of said first lower zone, means for controlling a second temperature condition of said second upper zone, means for controlling a second pressure condition of said second upper zone, means for generating ultrasound, and means for forming said fluid in the lower part of said vertical reactor;
• and wherein
• the first pressure condition being equal to or different than the second pressure condition, and
• the first temperature condition being different than the second temperature condition.
