A liquid mixture made up of 60% ethanol, 5% dissolved matter, and the rest water, by mass to a steady-state distillation column operating in a continuous regime. is fed. Two separate products are obtained from the distillation process, one of which is the column. The other is the product that comes out of its top (ball) and the other that comes out from its bottom (bottom). According to the column design, each The mass flow rate of the two products is the same and the product taken from the top of the column is 90% ethanol by mass. and does not contain any dissolved substances. 100 to distillation column Assuming that the liquid mixture is fed with a mass flow rate of kg/h a) Calculate the mass percent of the dissolved substance in the product taken from the bottom of the column b) Liquid fed into the distillation column of the mass of ethanol in the product taken from the bottom of the column Find the ratio of the ethanol in the mixture to its mass.
