What is short pass distillation?

Short-path distillation is a simple technique that involves the distillate traveling a short distance. This technique is used in many types of distillation and has been around for many years in several fields. This distillation is completed under pressure which decreases the boiling point of the liquid.

What is short path distillation used for?

Also known as fractional distillation, short-path distillation is a low-pressure evaporation technique used to separate materials from various compounds. Materials frequently extracted using short-path distillation include fatty acids, fragrances, fuels, oils, polyurethane, and CBD oil from hemp plants.

What are the apparatus used in distillation?

Thre are three essential pieces of distillation equipment needed to carry out the process; Reboiler or Pot – Used to heat the source liquid. Condenser – The heated vapour is cooled back to a liquid state. Receiver Flask – The device into which the concentrate/distillate is collected.

Which distillation is known as short path distillation?

Short path distillation or molecular distillation is a liquid-liquid separation process for high boiling, High viscosity, and heat sensitive, readily oxidisable materials. In the process of short path distillation, molecules escape from warmer liquid on vessel surface towards a cooler surface inside a condenser.

What is needed for short path distillation?

The short path itself is made up of a heating mantle and four major glass components: the boiling flask, the short path head, the receiving cow, and the receiving flasks. This is how you’ll heat the mixture inside the boiling flask. The head is the key to distillation.

How do you set up a short path distillation?

Short Path Distillation Procedure

1. Winterization.
2. Scrubbing and polishing.
3. Removal of all solvent in evaporator.
4. High temperature(140c) “punch” through all layers removing all water, alcohol, solvents, terpenes, etc..
5. Pour into load flask.

How do I set up a short path distillation?

Do you need a chiller for short path distillation?

This means we do not necessarily need a “chiller”. We just need a device that will keep our desired 50C temperature during the process. This 50C temp will keep our short path from clogging and will be “cold” enough to easily recondense any vapors that travel into the path of the condenser.

How do you use a short path distillation?

During the short-path process, a boiling flask is used to heat crude oil and the oil is agitated with a magnetic stirrer. The compounds are separated in the oil using heat until they transform into vapor. The vaporized compounds rise up and then are chilled back to a liquid using a condensing coil.
