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 fed 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. If the
“spent” wash water contains 15% salt and the crude oil contains 5% salt, determine the
concentration of salt in the “washed” oil product if the ratio of crud oil (with salt) to
water used is 4:1.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
