Solving Material Balance Problems Involving Multiple Subsystems

A cellulose solution contains 5.2% cellulose by weight in water. How many kilograms of 1.2% solution are required to dilute 100 kg of 5.2% solution to 4.2%  [Pg.163]

Salt in crude oil must be removed before the oil undergoes processing in a refinery. The crude oil is fed to a washing unit where freshwater feed to the unit mixes with the oil and dissolves a portion of the salt contained in the oil. The oil (containing some salt but no water), being less dense than the water, can be removed at the top of the washer. The spent wash water (containing salt but no oil) is removed at the bottom of the washer. If the spent wash water contains 15% salt and the crude contains 5% salt, determine the concentration of salt in the washed oil product if the ratio of crude oil (with salt) to water used is 4 1. [Pg.163]
