Continuing on with our work around physical chemistry, taking a look at gasses, morals, precious faith, precious and things that are like. We can first start off with some contextual learning, so the extraction as a process of separating substances from a mixture based on their soul abilities, are their relative soul abilities. So the salute is extracted from the carrier using the help of some sort of solvent, and the extraction is the minimum of the three components processes. So the extraction is a tertiary system, so from 50 80% relative saturation relation, we have gamma nor P is able to 9.500 p h star Garmin autism or fraction peers. The pressure pH stars of vapor pressure we start substitute in the vapor pressure is one of 68 millimeters of Mercury Pierce. 7 60 millimeters of mercury. Dominant becomes not 0.703 So saturation relation at the outlet stream we have pH. Star. It was another point, not five p get that in millimeters of mercury. So then we multiply No point No. Five by 7. 60 millimeters of mercury. So I got peak Age Star is able to 38 millimeters of mercury. And so from the answer in equations, the temperature at saturation could be calculated as negative 3.26 degrees Celsius. More balance off the condenser is as follows we have. And no, it is ableto end one at 1.5. Kill them all at one take we're not 10.703 multiplied by n dot north people to not 0.95 and one talk. So we have equation to in equation three. So then we generate and don't know is 2.81 killer malls a minute on n dot juan is equal to 9.68 to kill a moles per minute. Eso the most of nitrogen in the outlet stream is no 0.6479 killer models Volume of nitrogen. We have 14.5 us see? And, um so the flurry of nitrogen to the driest 14.5 SCM Uh huh. Moving on to part B now. So we have the relation for the 50% relative saturation, and the Condenser inlet is as follows. So we have not 0.5 zero p h star sequel to govern our P we re arrange and substitute PN for Gap P each star favor. Pressure is equal to turn 685.6 millimeters of mercury. So from equation one that we saw previously, the temperature of saturation t zero is 187 degrees Celsius. So the saturation of the outlet condenser pH star is not point No. Five p. And now we can multiply. No, we're not five by 76 years. There were millimeters of mercury, it's of P H staff comes 3 80 millimeters Are Makary so moving on. So from previous equation, we have the outlet temperature saturation t wan that we can define us 48.2 degrees Celsius So the ratio of the volumetric flow rate probably in moving on entering the condenser. We have fedora want divided by video no secret tow N one r t one of p drive by end to our t to overpay. So we substitute in our moles about n one or not and zero that we defined previously r t one or not zero which is 3 to 1 Kelvin and for 60 Kelvin respectively. So we have the one over v not is not 0.682 kill the malls per minute multiplied by 3 to 1 Kelvin, divided by 2.1 a kill more a minute multiplied by 4 60 kelvin. We got a value off, not point to two. So therefore the final gas temperature is 48.2 degrees Celsius and the volume ratio volumetric flow rate it's now point to to eso for part B cost of compressing and cooling. A 10 atmosphere is required for the first part. The cost of calling to negative 3.24 degrees Celsius as well as the installation costs and the cost of utilities that will need are required to find the cost effectiveness off part A and part B that we looked at. And so therefore we can determine, uh, part a is more cost effective.
