The presence of BTEX compounds (benzene, toluene, ethylbenzene, xylene) in the feed gas significantly impacts the operation of a glycol dehydration unit by leading to increased glycol losses, potential environmental concerns, and operational problems. Glycol dehydration units use glycol solvents, like triethylene glycol (TEG), to absorb water from natural gas. BTEX compounds, which are volatile aromatic hydrocarbons, are also absorbed by the glycol solvent to some extent. However, unlike water, BTEX compounds are not effectively remo....
