Embodiment 1
[0019] Example 1 field for a field of high-pressure nitrogen gas flooding EOR oil by-product process embodiment associated gas (carbon dioxide has been removed), the nitrogen content 29.23vol%, a water content 2.55vol%, the total content of hydrocarbons such as methane is 68.21vol%, the average for the associated gas flow 2000Nm 3 / h, using the multi-technical integration process including gas film separation, adsorption dehydration, turbine expansion, and steam compression refrigeration, in principle figure 1 As shown, concentrated methane is separated in high efficiency and high yield to produce commercial natural gas that meets the national standard "GB17820-2012".
[0020] Nitrogen-containing gas (S1) after removal of carbon dioxide, first entering the first compressor (1), boost to 1.80 MPAg, enter the first cooler (2), cool to normal temperature, enter the gas-liquid separation can (3) The condensed water is separated; the gas eliminates the top of the gas-liquid separation ...
