Vape oil, on the other hand, is hashish oil which is derived from marijuana. While some strains of cannabis offer recreational usages of vape oil (depending on the amount of THC), it’s liked by medical marijuana users as a fast way of administering CBD – and on occasions THC too – for pain relief. Vape oil is smeared onto a coil and then heated (for vape pens), or decanted into an oil tank. Some oil vaporizing devices heat the oil via a metal plate which in turns heats the coil, which leads to the vaporizing. Hashish oil tends to be highly concentrated and a suitable medication for patients who need high doses to find relief.
Antifreeze wastewater often contains water soluble oils which are emulsified with water to make a homogeneous mixture. These oils will break out of the solution or emulsion upon heating in the evaporator and will float to the surface once the boiling stops. This oil can easily be decanted in the ENCON Thermal Evaporator either manually using the oil weir or automatically by using the optional auto-decant package. It is often the case that this decanted oil can be sold or used as waste fuel further improving the cost effectiveness of evaporation as a spent coolant minimization method.
Another example of decantation is the regeneration of used chiral stationary phase (CSP). The CSP to be decanted is gently mixed in a container with a compatible solvent to form a suspension. The suspension is allowed to rest for a period of time, after which the supernatant is carefully poured off. The supernatant contains the undesirable constituents of the former suspension, while the leftover sediment in the container is clean, reusable CSP. Decantation should be done directly after sedimentation. This process is also used in erected pure iron from iron ore.
