Off-gas Tank(C303)
The off-gas tank recovers the used CO2.The extractor works intermittently. When each period of extraction ends, the material inside the extractor should be replaced. To cut the cost, the CO2 in the extractor should be recovered and stored. When a certain quantity of CO2 is recovered, the compressor compresses it to use it again. The parameters are shown in table 3.8 and its simplified structure is shown in Fig. 3.9.
