Embodiment 1
[0090] Devices for oil and gas recovery include:
[0091] Oil and gas feed line, gas-liquid separation tank I1, compressor I2, light and heavy gasoline separation tower 3, compressor II4, light hydrocarbon-light gasoline separation tower 5, compressor III6, cooler I7, gas-liquid separation tank II8 , rich gas desulfurization tower 9, rich gas alkali washing tower 10, liquid hydrocarbon desulfurization tower 11, liquid hydrocarbon desulfurization reactor 12, cooler II 13, feed tank 14, absorption tower 15, demethanizer 16, deethanizer 17. Depropanizer 19, propylene rectification / 20 and absorbent recovery tower 21;
[0092] Wherein, the oil and gas feed line is connected with the inlet of the gas-liquid separation tank 11, the top of the gas-liquid separation tank 11 is connected with the compressor 12, the light and heavy gasoline separation tower 3 in turn, and the bottom of the tank is connected with the light and heavy gasoline separation tower 5;
[0093] Light and heavy g...
Embodiment 2
[0128] using as figure 2 The shown technological process recovers oil and gas, and the difference from Example 1 is: in this example, the part of the mixed C4 component S-15 extracted from the bottom of the depropanizer 19 is used in the deethanizer 17 as the Absorbent to separate C2 components.
[0129] Wherein, the mixed C 4 absorbent S-12 drawn from the bottom of the depropanizer 19 and sent back to the deethanizer 17 is 5000kg / h, and the recovered product compositions, flow rates and properties are shown in Tables 5 and 6 :

Embodiment 3
[0136] using as image 3 The shown technological process recovers oil and gas, and the difference from Example 1 is: in this example, the sequence of demethanization, depropanization, and deethanization is successively used to separate light hydrocarbons, wherein, the top of the deethanizer 17 is separated. Part of the propane taken from the bottom of the propylene rectifying tower 20 is used as the absorbent S-11 to separate the C2 component.
[0137] Wherein, the propane absorbent S-11 that is sent back to the deethanizer 17 extracted from the bottom of the propylene rectifying tower 20 is 6500kg / h, and each product composition, flow rate and property recovered are shown in Table 7, Table 8:
