Methods of producing a CBD/THC oil are disclosed. In some embodiments, the method may include extracting CBD/THC from plant matter using one or more solvents, winterizing the solvent extract, and evaporating the one or more solvents from the winterized extract. The method may additionally include distilling the evaporated extract via a short path distillation apparatus to produce an initial distillate oil, mixing the initial distillate oil with at least one solvent, and running the mixture of initial distillate oil and at least one solvent through a chromatography column to produce an effluent. The method may further include evaporating the at least one solvent from the effluent, distilling the evaporated effluent via a short path distillation apparatus to produce a final distillate oil, and mixing one or more desired terpenes with the final distillate oil.

The present invention provides a rotary evaporator capable of accurately quantifying concentrated liquid and/or distillate. A distillation flask is improved into a structure having a liquid discharge opening formed at the bottom, and/or a spherical collecting flask is improved into a structure having a liquid release opening formed at the bottom. Concentrated liquid and/or distillate can be discharged without dismounting the distillation flask and/or the collecting flask. In addition, fine metering scale tubes and quantitative capacity increase units are disposed at the liquid discharge opening and/or the liquid release opening, there is a valve on the top and another valve on the bottom of each tube, so that the constant subtle changes of the amount of concentrated liquid and/or distillate can be observed, and an accurate amount of concentrated liquid and/or distillate can be discharged.

The present invention relates to a process for purifying a composition comprising a hydrohalocarbon B comprising the steps of: i) providing a composition A1 comprising a hydrohalocarbon B and at least one impurity C different from said hydrohalocarbon B, ii) compressing said composition A1, and optionally cooling it, so as to obtain said hydrohalocarbon B in liquid form in order to form a liquid stream A2 comprising said hydrohalocarbon B, iii) distilling said stream A2 obtained in step ii) in order to form and recover a stream A3 comprising said hydrohalocarbon B, characterized in that step iii) is carried out in a pressurized distillation device comprising one or more rotating packed beds.

Integrated rotary evaporator apparatuses are provided. Such rotary evaporators include a vertically oriented evaporator for evaporating a sample to form a sample evaporate, a mixing apparatus for mixing the sample in the evaporator, a condenser for condensing the evaporated sample into a condensate, a collection vessel for collecting the condensate, a vacuum pump to create a vacuum in the evaporator, and a refrigeration system integrated into the condenser, where all components are integrated into a single apparatus. Standalone large-scale chillers for cooling a liquid, vapor or other medium are also provided. Such chillers include a heat exchanger or evaporator, a condenser, a compressor, and a temperature controller, all integrated into a single standalone chiller usable with any vessel or reservoir containing liquids, vapors or other medium from which heat is to be removed. Methods of using such devices to distill, evaporate and/or cool a sample or medium are provided.

A system and method for decontaminating a fluid and recovered vapor, particularly processing and recycling water used in an oil zone steam process, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated water flow is recovered after separation from a combined oil and water flow from an oil well. The clean water vapor flow is preferably passed through a steam generator to produce the steam used in the oil zone steam process. The steam is injected into the oil zone of a designated well and then extracted as the combined oil and water flow. Once primed with sufficient external water, the system and method is designed to operate continuously with minimal replenishment because of the water/vapor/steam cycle.
