Air Separation Unit: An air separation unit separates atmospheric air into its primary components, typically nitrogen and oxygen. Sometimes they will be used to separate argon and other rare inert gases.
Catalyst: A catalyst is a substance that promotes a chemical reaction between two or more reactants. The catalyst is not consumed during the reaction process.
Distillation: A process that consists of removing gas vapour from liquids by heating and then condensing to a liquid state for the purposes of fractionation, purification or creation of a new substance.
Feedstock: Raw material used for chemical processes such as hydrocarbons used as basic materials in a refining or manufacturing process.
Reactant: A chemically reacting substance.
Reactor: A vessel for an industrial chemical reaction.
Synthesis: The production of a substance by the union of elements or simpler chemical compounds or by the breaking up of a more complex chemical compound.
Synthetic or synthesis gas: Gas created by the synthesis process described above.
