Degassing & Decarboxylation

To properly prepare crude oil for further refinement (such as distillation), a degassing procedure should be performed. The terms degassing, devolatizing, or even decarboxylation, are often used to describe this procedure. Although these terms are interchangeable to a degree, they actually mean very different things which can make this a confusing subject when you're trying to learn the steps of processing cannabis/hemp crude oil. The goal of this article is to help you understand the difference between these terms and be able to use them to purchase the right equipment for your processing facility.

A note on Degassing:

Decarboxylation and devolatilization can be achieved by using the same equipment and process. This process is often referred to as degassing. In the following paragraphs, we will go into detail about the chemical process of decarboxylation, the physical process of devolatilization, and how both of them are achieved through degassing.

Decarboxylation

Decarboxylation is a type of chemical reaction that releases carbon dioxide from non-activated acidic compounds. This reaction causes those non-activated compounds to become activated. Activation enhances the desired physical and psychoactive effects of these compounds. Because of this, it is often a vital step in cannabis/hemp processing.

Decarboxylation can be performed on plant material as well as on crude oil. Most often, this is where the term originates. When performing decarboxylation on plant material, heat is applied. The heat causes a chemical reaction and activates those compounds within the plant material.

This should not be confused with decarboxylation as it relates to degassing or devolatilization. Those can only be achieved when using crude oil that has undergone previous processing steps.

One of those steps would be winterization and solvent recovery, which often leaves behind 1 to 10% of the solvent that must be removed. To do this, the crude oil is heated with a variety of equipment, which will be discussed further below.

Heating the crude oil to a high temperature will decarboxylate the compounds within the oil, thereby activating them. But, chances are most of those compounds have already been activated in previous processing steps. For example, if the plant material was activated using heat, the crude oil coming from that plant would also be activated. Removing that 1 to 10% of solvent, using heat, can also be called "devolatilization".
