Abstract: Methods and systems for separating C3 hydrocarbons from lighter hydrocarbons, carbon monoxide, carbon dioxide, and water are provided. In certain embodiments, the methods include feeding a gaseous mixture including C1, C2, and C3 hydrocarbons and benzene solvent to the absorber column where benzene solvent selectively absorbs C3 hydrocarbons. The methods can further include removing a first stream comprising benzene solvent and absorbed C3 hydrocarbons from the absorber column, and feeding the first stream to a stripper column where benzene solvent is separated from C3 hydrocarbons, and removing a second stream comprising C3 hydrocarbons from the stripper column.
