6.8 Raw natural gas ﬂowing at 1000 mol/h contains 15.0 mol% CO₂,5.00 mol% H₂S, and 1.41 mol% COS, and the balance is methane.The separations system shown in Problem Figure 6.8.1 is capable of handling a certain ﬂow rate of raw natural gas. Any ﬂow rate higher than this limit is sent into the bypass around the separation unit and then mixed with the treated gas to yield the ﬁnal product. The ﬁnal product is to contain no more than 1.00 mol% H₂S and no more than 0.300 mol% COS. Stream 6 leaving the separation unit contains H2S and COS only. The separations unit maximum ﬂow rate it can handle is 900 mol/h; any ﬂow beyond this must go to the bypass system. Find out the ﬂow rate of the treated natural gas stream and ﬂow rate of the reject stream from the separator? (948.2, 51.8 mol/h)
