What Does Solvent Recovery Mean?
Solvent recovery refers to the recovery and recycling of solvents that have been used in the cannabis extraction process.
Chemical solvents, especially in the commercial cannabis industry, are expensive. The high cost of solvents makes solvent recovery an ideal way to save money. Solvents such as butane, hexane, ethanol, propane, and isopropyl alcohol that are used in cannabis extraction processes can be recovered for recycling and later use.
After use, the solvents are recovered and separated through functions of a distillery. Special distillery tanks are used to heat and separate the solvents when they reach boiling and condense into vapor. The steam vapor is collected and funneled to an air-cooled condenser. Upon cooling, the solvents again turn into a pure liquid which can be reused.
