New Numerical Model Calculates Light Alkanes Solubility in TEG

New model, which cover the full range of dehydration-plant operating conditions and wide range of experimental data results, estimate the amount of CH4, C2H6 and C3H8 absorbed per volume of triethylene glycol (TEG) circulated vs. the partial pressure of light Alkanes and the absorber 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.
