The Caprolactam should be extracted from a stream Caprolactam-Benzene (100 kmol/h) by using water (=Extract, E) at T = 20 °C. In order to have an economic process, a counter-current process is designed. The benzene stream (=Raffinate, R) should be in another process step re-used, therefore its content in Caprolactam should not exceed xRC = 0.02. a) Calculate the minimum amount of water for the following case: xFC = 0.25. b) Use the overall mass balance and list all the inlet and outlet streams and their composition.
c) Calculate graphically the number of theoretical stages for the Mixer-Settler, when working with a water stream which is 1.5 times higher than the minimum amount of water.

Which metal exist in liquid state and can be cut with knife ?

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
