Solubility of Hydrocarbons in Physical Solvents

Physical solvents are used to treat natural gas streams in a number of ways. Glycols such as ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG) and methanol are commonly used in wet gas dehydration processes. EG and methanol are also injected into wet gas to act as hydrate inhibitors. Acid gas removal can be accomplished by the physical solvent DEPG, which is a mixture of dimethyl ethers of polyethylene glycols, and b
