Embodiment 1
[0034] Contains CO 2 The mixed gas composition (mol fraction) is as follows:
[0035] CO 2 is 0.4210; H 2is 0.5235; DMCARB is 0; CO is 0.0141;
[0036] Ar is 6.8000E-03; METHANE is 8.7000E-03; N 2 is 0.0254;
[0037] h 2 S is 4.60000E-04; H 2 O is 0,
[0038] The temperature of the mixed gas is 28°C and the pressure is 2.6MPa;
[0039] Mixed gas and absorption tower top to remove CO 2 After heat exchange, the purified gas drops to 23.2°C and enters the absorption tower from the lower part. The dimethyl carbonate from the absorbent storage tank at 25°C exchanges heat with the liquid phase of the secondary desorption tank and enters the absorption tower from the upper part after reaching 14.3°C. Two-phase Countercurrent contact and absorption mass transfer occur in the column. The gas phase flow rate is 22121KG-MOL / HR, and the liquid phase flow rate is 54323KG-MOL / HR. The temperature at the top of the absorption tower is 15.5°C and the pressure is 2.55MPa; the tempera...
Embodiment 2
[0047] Contains CO 2 The mixed gas has a temperature of 27°C and a pressure of 2.9MPa. The composition (mol fraction) is as follows:
[0048] CO 2 : 0.4210; H 2 :0.5235:DMCARB:0;CO:0.0141;
[0049] Ar: 6.8000E-03; METHANE: 8.7000E-03: N 2 : 0.0254;
[0050] h 2 S: 4.60000E-04; H 2 O: 0;
[0051] Mixed gas and absorption tower top to remove CO 2 After heat exchange, the purified gas drops to 23.1°C and enters the absorption tower from the lower part. The dimethyl carbonate from the absorbent storage tank at 25°C exchanges heat with the liquid phase of the secondary desorption tank and enters the absorption tower from the upper part after reaching 15.1°C. Two-phase Countercurrent contact and absorption mass transfer occur in the column. The gas phase flow rate is 22117KG-MOL / HR, and the liquid phase flow rate is 58611KG-MOL / HR. The temperature at the top of the absorption tower is 15.8°C and the pressure is 2980KPa; the temperature at the bottom of the tower is 29.2°C ...
