 * Agglomeration -** a jumbled cluster or mass of varied parts

**Asphaltene** - aromatic material present in petroleum that is insoluble in n-paraffins but soluble in aromatic solvents

**Cloud Point/Wax Appearance Temperature (WAT)** - temperature at which paraffin wax precipitates and falls out of solution

**Flocculate** - To form masses, as a cloud or a chemical precipitate; form aggregated or compound masses of particles.


 * Heteroatoms -** any atom that is not carbon or hydrogen


 * Nucleation** - the initial process in which crystals form from solution

**Paraffins** (also referred to as alkanes) - chemical family of saturated hydrocarbons

**Paraffin Wax** - solid state, long chain n-alkanes that precipitate out of cooled crude oil. The paraffin wax found in crude oil follows the general formula C n H 2n+2 .

**Pendant Chains** -oligomeric or polymeric offshoot extends from the backbone chain of a polymer

**Pour Point -** the lowest temperature at which a substance will flow under given conditions

**Rheology** - the study of the flow of matter

**Wax** - saturated hydrocarbons that contain more than 16 carbon atoms in the paraffin series (C 16 -C <span style="font-family: Arial,Helvetica,sans-serif; vertical-align: sub;">40 <span style="font-family: Arial,Helvetica,sans-serif;">) and are in solid state at room temperature


 * Wettability -** the degree or extent to which something absorbs or can be made to absorb moisture
