The invention provides a method for enhanced absorption of light hydrocarbon, which is mainly characterized by comprising the following steps: adopting W/O emulsion as an absorbent for the enhanced absorption of the light hydrocarbon and gas as a disperse phase (namely bubbling), wherein the W/O emulsion is a continuous phase and generates absorption operations in an absorbing tower; preparing various W/O emulsions with different oil phases, different grain sizes, different surfactant types and concentrations as an absorbent for absorbing the light hydrocarbon; and using random motions of disperse phase water drops in the oil phases to enhance the gas-liquid mass transfer process so as to achieve the aim of the enhanced absorption of the light hydrocarbon, wherein the absorptive amount ina unit time can be improved by about 10 percent. The method has the advantages of mild conditions, simple and convenient operations, wide range of application and high light hydrocarbon yield, and canbe resolved under proper conditions, the emulsion does not break, surfactants and oil phases have wide selection range and can be recycled, the enhanced mass transfer is obvious, and the method can satisfy requirements on absorbing the light hydrocarbon in production. The method is easy to popularize and use in the process of factory production.
