Extracting the most profit out of your process.

Cannabis and Botanical Extraction

Producing commercially pure CBD and THC requires a keen scientific understanding of the botanical extraction processes to maximize yield and output. Thermaline is at the forefront of the CBD/THC extraction industry with a full line of plate and tubular heat exchangers for your extraction process with experienced engineers that understand your process challenges and have solutions.

Ethanol Extraction:

Deep Chilling: Ethanol is deep chilled to subzero temperatures in plate heat or tubular heat exchangers to be introduced into the extraction vessel. A subzero chiller with special heat transfer fluid, such a Dynalene, is used as the cooling media.

Evaporation: After the ethanol solvent has extracted the CBD/THC oils from the cannabis mixture is then brought to evaporation temperature in a plate or tubular heat exchanger exiting into a flash tank were the ethanol vapors are reclaimed as a gas and the CBD/THC's as an oil.

Condensing: The Ethanol vapors are then brought from a gaseous state to a liquid state in a plate or tubular heat exchnager before being sub-cooled again.

Economizer: A plate or tubular heat exchanger is used to recover energy (BTU's) of the two ethanol streams between evaporation and deep chilling which greatly reduces the load on the chiller.

Hydrocarbon Extraction

Deep Chilling: Hydrocarbons such as Propane or Butane are deep chilled into a liquid state in a plate or tubular heat exchanger then introduced as a solvent into the extraction vessel stripping CBD and/or THC oils from the plant. A buzero chiller with special heat transfer fluid, such as Dynalene, is used as the cooling media.

As the mixture is released to ambient conditions the hydrocarbons are evaporated and recovered while the oils are collected.

Condesning: A plate or tubular heat exchanger is used to condense the gaseous hydrocarbons into a liquid state which is then re-used for another stripping operations.
