Chapter 4, Problem 4.28P
In the commercial production of sugar (sucrose), the product crystals are washed and centrifuged to partial dryness. The crystals are then sent through a rotary dryer where they are contacted with a hot stream of air that reduces the moisture content from 1.0 wt% to 0.1 wt%. The ratio of w et sugar to inlet air fed to the dryer is 3.3 kg wet sugar/kg inlet air. The inlet air contains 1.5 mole% water.
- Draw and label the flowchart and do the degree-of-freedom analysis.

In a process producing KNO3 salt, 1000 kg/h of a feed solution containing 10 wt% KNO3 is fed to
an evaporator, which evaporates some water at 422 K to produce a 50 wt% KNO3 solution. This is
then fed to a crystallizer at 311 K, where crystals containing 98 wt% KNO3 are removed. The
saturated solution containing 37.5 wt% KNO3 is recycled to the evaporator. Calculate the amount of
the recycle stream R in kg/h and the product stream of crystals P in kg/h.
Solid calcium (CaF2) reacts with sulfuric acid to form solid calcium sulfate and gaseous hydrogen fluoride. The HF is
then dissolved in water to form hydrofluoric acid. A source of calcium fluoride is fluorite ore containing 96 wt% CaF2
and 4% SiO2.
In a typical hydrofluoric acid manufacturing process, fluorite ore is reacted with 93 wt% aqueous sulfuric acid, supplied
15% in excess of the stoichiometric amount. Ninety-five percent of the ore dissolves in the acid. Some of the HF formed
reacts with the dissolved silica in the reaction
6 HF + SIO2 (aq) – H2SİF6 (9) + 2 H2O (1)
The hydrogen fluoride exiting from the reactor is subsequently dissolved in enough water to produce 60 wt%
hydrofluoric acid. Calculate the quantity of fluorite ore needed to produce a metric ton of acid. Express your answer
into three significant figures.
Two aqueous sulfuric acid solutions
are available at a processing facility:
20.0 wt% H2SO4 (sg = 1.139)
60.0 wt% H2SO4 (sg = 1.498)
It is desired to mix the two solutions
such that the final product has a
concentration of 4.00 M (sg-1.213).
There is 100 kg of the 20% solution
available. If all of this is to be used,
calculate:
The mass of 60% solution needed
The mass and composition of the final
product

- A single effect evaporator is used to concentrate 10 000 kg / hr of tomato juice from 5% total solids to 30% total solids. The juice enters the evaporator at 15 ° C. The evaporator is operated on Steam (80% quality) at 143.27 kPa. The vacuum in the evaporator allows the juice to boil at 75 ° C.

The liquid outlet stream of the flash vessel is then sent to a distillation column with a partial condenser to further separate the components. 90% of the butane in the feed to the column is recovered in the overhead vapor product (distillate), along with small amounts of octane. The bottoms product contains octane which accounts for 75% of the octane in the fresh hydrocarbon feed (to the flash vessel).

- 2. In an ethanol production plant, a separator produces a 99% ethanol product from a feedstock stream containing 85% water and 15% ethanol at a rate of 450 Ib/min. The separator has two outlet streams: the ethanol product outlet stream (99% ethanol) and a residual water stream. 30% of the feedstock is bypassed and mixed with the residual water stream leaving the separator. If 60% of the ethanol entering the separator is recovered in the product stream, determine the composition of the residual water stream just after leaving the separator and the composition of the residual stream after mixing with the bypass stream.arrow_forwardNaturally occurring barium sulphate is converted into water–soluble formby heating with carbon, thus reducing the sulphate to barium sulphide(BaS). The resulting reaction mixture, “barium black ash”, contains 65%w/w soluble BaS and is to be leached with water. Black ash is to be fedto a tube mill at 100 tonnes per day, together with the overflow from thesecond of a cascade of thickeners, and the effluent from the mill is fed tothe first thickener. All the barium is dissolved in the mill. The strongsolution leaving the first thickener contains 20% w/w BaS by weight.Each thickener delivers a sludge with 1.5 kg liquid per kg of insolublesolid. Both liquids leaving each thickener are to have the same BaSconcentration. BaS lost with the final sludge should not exceed 1 kg perday.How many thickeners are needed?arrow_forwardTo prepare a delicious banana milk on an industrial scale, there is an experimental process that consists of seven unit operations. A stream of banana (whose components are fruit, peel, and moisture) is fed to a peeler, where 99.9% of the peel is removed. This stream should become pulp, so it is mixed with an additive Q to avoid pulp oxidation. This mixture is then sent to an extruder press wherein a stream of a 50:50 mixture of additives Q and R is added. The resulting flow of 30 kg/h has a composition of 2% additive R and 5% additive Q. This flow is then fed to an agitated mixer. To the same mixer is fed a dairy stream of 250 kg/h that contains 70% milk (the rest is water) and a sweet aqueous stream that contains 30% sugar. For each 25 kg/h of dairy flow, 2 kg/h of the sweet flow is fed. The stream that leaves the agitated mixer has 5% fruit and 0.005% peel and enters a series of two thermal processes in which each operation allows 5% of the water and 2% of the milk to evaporate.

A customer has ordered the airplane but requested that its total weight be reduced by 10 percent for fuel saving purposes. An engineer in the design and analysis department has suggested that the weight saving objective can be accomplished by replacing the current aluminum alloy of the floor beams with another one containing 3 wt% Li and 1 wt% Cu. Is this possible? Answer the question by first determining the weight saving that will take place using the Al-Li alloy. Assume weighted averages of density and use the following densities for the mentioned materials: Al = 2.70 g/cm³ Cu = 8.92 g/cm³ Mg = 1.74 g/cm³ Li = 0.53 g/cm³arrow_forwardQ4/in a two stage process, acetic acid (A)is extracted from water (W) into hexanol (H) in a liquid-liquid extraction vessel and the extract is subsequently separated by distillation.

Pure hexanol is feed to the column to extracted the acetic acid. The water-rich stream leaving the vessel is 99.5wt% water and the balance acetic acid. The hexanol-rich extract from the vessel is feed to a distillation column. The composition of the distillate is 96wt% acetic acid and the balance hexanol. The bottom stream contains 97.2wt% hexanol and recovers 95% of the hexanol feed to the liquid-liquid extraction vessel.
