New model, which cover the full range of dehydration-plant operating conditions and wide range of experimental data results, estimate the amount of CH(4), C(2)H(6) and C(3)H(8) absorbed per volume of triethylene glycol (TEG) circulated vs. the reduced partial pressure of light Alkanes and the absorber reduced temperature. TEG has a tendency to remove the hydrocarbons. Hydrocarbon solubility is a major factor when considering the use of a physical solvent. Quantifying this amount of absorption is critical in order to minimize hydrocarbon losses or to optimize hydrocarbon recovery. This article provides comparisons with experimental data.
