You got a new job with Home Paint Pte Ltd who is selling paints to various retailers. The company is able to produce number of unique colours based on blending with several colour based pigments like yellow,red and blue. In order to produce magenta colour product,P, a paint mixture stream,F1,is mixed with another paint mixture stream,F2.F1 contains 30wt% of blue pigment in water whereas F2 contains 12.0wt%red pigment in water.It is given the cost of F1and F2 are $35.00/kg and $20.00/kg,respectively.In order to obtain the magenta colour product,P,the ratio of F1/F2 should be equal to 2.
a)Draw and label the flowchart of the process unit by indicating all the input and output process variables.Perform the degree of freedom (DOF) analysis.
b)By taking basis of calculation,P=10kg/hr,calculate the mass flow rates of F1 and F2.Determine the water composition(wt%) in P.Subsequently,determine the selling price of P ($/kg) in order to make a 100% profit.
c)As the demand of the magenta colour increased, you are required to redesign a larger mixing unit which is capable to produce 350 metric ton/year of P. Using the information from part (b), determine the required scale-up factor.
