1. A method for treating an oil gas, comprising the following steps:
(1) subjecting a hydrocarbon material to a first gas-liquid separation to obtain a first gas-phase material mainly containing H2 and C1-C4 and a first liquid-phase material mainly containing C5+; and
(2) subjecting the first gas-phase material to impurity removal to obtain an impurity-removed first gas-phase material, subjecting the impurity-removed first gas-phase material to a second gas-liquid separation to obtain a second gas-phase material mainly containing H2 and C1-C2 and a second liquid-phase material mainly containing C3-C4; subjecting the second gas-phase material to gas phase impurity removal to obtain an impurity-removed second gas-phase material, and subjecting the second liquid-phase material to liquid phase impurity removal to obtain an impurity-removed second liquid-phase material; the impurity-removed second gas-phase material and the impurity-removed second liquid-phase material being mixed and then subjected to a separation treatment to obtain a dry gas product mainly containing H2 and C1, a C2 product mainly containing C2, a C3 product mainly containing C3, and a C4 product mainly containing C4.
