The company that currently you are working with, D'herbalicious has made a strategic decision to provide a fine chemical C, that has been extracted from an algae fermentation broth to the cosmetics industry. You have been assigned to an established extraction plant in North Johor. Feed of 1200 kg/h containing 55wt% of fine chemicals in aqueous fermentation broth (B) is to be extracted at 25°C in a continuous countercurrent system with pure solvent, A to obtain a raffinate containing 0.10 wt% of C. Using the following equilibrium data given below with an equilateral-triangle diagram: a) determine the minimum flowrate of solvent [6 marks] b) suggest a suitable actual solvent rate and conclude the number of stages required for the extraction [8 marks] c) calculate the flow rate and composition of each stream leaving each stage and determine the overall recovery [6 marks] 0.5 0.7 1.0 1.6 2.1 3.8 6.5 A wt% dalam lapisan akues wt% in aqueous layer B 93.5 82.2 72.0 62.7 57.0 50.2 41.7 6.0 17.1 27.0 35.7 40.9 4610 51.8 9.1.0 73.8 592 475 40.0 33.7 26.31 A wt% dalam lapisan pelarut wt% in solvent layer B 0.3 M 2.6 MOB 50 1.9 8.7 25.7 38.5 48.2 540 The company that currently you are working with, D'herbalicious has made a strategic decision to provide a fine chemical C, that has been extracted from an algae fermentation broth to the cosmetics industry.
