Triethylene glycol is a member of a homologous series of polyethylene glycols.It is a colorless, odorless and stable liquid with high viscosity and a high boiling point. . Apart from its use as a raw material in the manufacture and synthesis of other products, TEG is known for its hygroscopic quality and its ability to dehumidify fl

Ethylene glycol is widely used to inhibit the formation of natural gas clathrates (hydrates) in long multiphase pipelines that convey natural gas from remote gas fields to a gas processing facility. Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic salts.
Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n centiStokes. For gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 0.5 to 5 kg/m^3.
Diethylene glycol is one of several glycols derived from ethylene oxide. Glycols related to and co-produced with diethylene glycol and having the formula HOCH 2 CH 2 (OCH 2 CH 2) n OH are: n = 0 ethylene glycol ("antifreeze"); monoethylene glycol MEG; n = 1 DEG; n = 2 triethylene glycol, TEG, or triglycol; n = 3 tetraethylene glycol; n = 4 ...
The proportionality factor is the dynamic viscosity of the fluid, often simply referred to as the viscosity. It is denoted by the Greek letter mu ( μ ). The dynamic viscosity has the dimensions ( m a s s / l e n g t h ) / t i m e {\displaystyle \mathrm {(mass/length)/time} } , therefore resulting in the SI units and the derived units :
