Solvent Recovery and Distillation

The term ‘solvent’ refers to several chemical substances which are used to dissolve or dilute other substances or materials. They are usually organic liquids.  Solvents usually have a low boiling point and evaporate easily or can be removed by distillation, thereby leaving the dissolved substance behind. Solvents should therefore not react chemically with the dissolved compounds—they must be inert.

What Extraction technique is right for you?

The cannabis market uses three main extraction techniques: CO2, liquefied hydrocarbons, and ethanol extraction.  Below explains  each method and how the extraction takes place and who and why some would use one specific method over another.

Don’t Get Fooled By These Common Vacuum Processing Myths

Rotary evaporators are advanced scientific instruments that are commonly used in chemical laboratories, processing laboratories and in research to facilitate fractionation. This separation process allows the solvents to be removed gently through evaporation and the precise control of the temperature.

What is Solvent Recovery?

Solvent recovery is the process of extracting target products from waste or by-product solvents generated during the manufacturing process. These chemicals can then be repurposed, reducing the need to produce or purchase new solvents, while eliminating a large amount of waste and removing potentially hazardous substances from the primary processed material

Moisture in Oil Transformer Tanks: Avoiding Mechanical Breakdowns

Moisture in Oil Transformer Tanks: Avoiding Mechanical Breakdowns Remember the ol’ transformer oil purification experiment from applied chemistry class? Thinking of it as you learn about moisture and oil contamination can be very useful. Internal moisture in transformer oil tanks is not distributed uniformly, and can be concentrated in the most dangerous parts of the system. Water in the presence of oxygen, even at microscopic levels, is a contaminant that reduces the insulation properties of Oil. Water enters into the transformer oil over time, which reduces the oil’s dielectric (insulation) properties.  As the transformer becomes wetter, it decays even faster, which increases the
