In a solid - liquid extraction process operated according to the principle of continuous reverse current, the oil of a nutrient will be extracted with pure hexane. A mixture containing 7000 kg of inert solid, 1500 kg of oil and 500 kg of hexane enters the process per hour. The upper stream leaving the total stage contains 65% hexane and 35% oil by weight. A total of 85% of the oil in the inlet current will be recovered. The underflow is constant at N=2.0 kg inert solid/kg solution; a. Find the amount and composition of the output current
A spent sulfuric acid solution is brought up to strength for a pickling process in a mixer. Spent solution at 3% sulfuric acid (by weight) is mixed with a 50% solution (by weight) to obtain the desired product concentration of 40% acid by weight. All are aqueous solutions. Determine all flow rates on the basis of 100 lbm per hour of product. If the actual flow of the spent stream is 300 lbm per hour. What must the flow rates of the stream be?
Air with a dry-bulb temperature of 38oC and a wet-bulb temperature of 27oC is scrubbed with water to remove dust. Water temperature is maintained at 25oC. The air leaving the scrubber is in equilibrium with water. It is then heated to 93oC in an air preheater and admitted to an adiabatic rotary drier. The air leaves the drier at 49oC. The material losses moisture at a rate of 0.05 kg of water per kg of product. The total product is 1000 kg/h. Determine the following (Use a psychrometric chart): a) Total weight of dry air used per hour. Answer: b) Total volume of air leaving the drier. Answer:
A solution containing 100 lbm KNO 3/100 lbm H 2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3 crystals suspended in saturated solution) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (lbm/lbm feed) and the solid-to-liquid mass ratio (lbm crystals/lbm liquid) in the slurry leaving the crystallizer.
(a) Water in vadose zone contains chlorobenzene of concentration 40 mg/L. What is the equilibrium concentration soil air in contact with this solution?

A tank, containing 1520 liters of liquid, has a brine solution entering at a constant rate of 3 liters per minute. The well-stirred solution leaves the tank at the same rate. The concentration within the tank is monitored and found to be c(t) = e(-t/800)/80 kg/L. Determine the amount of salt initially present within the tank. Initial amount of salt = ? kg. Determine the inflow concentration cin(t), where cin(t) denotes the concentration of salt in the brine solution flowing into the tank. cin(t) = ? kg/L
Calculate the required chlorine concentration for a direct filtration water treatment process at a temperature of 20 oC and pH of 8.0. The t10 time in the clear well is 8 minutes. After the Clearwell, the travel time in the pipeline is 10 minutes. Provide your answer with units of mg/L
A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 9.0 mole% methane in air flowing at a rate of 7:00 x 102 kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. Calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (Note: Air may be taken to consist of 21 mole% O2 and 79% N2 and to have an average molecular weight of 29.0.)
Cereal is being dried in a vertical drier by air flowing countercurrent to the cereal. To prevent breakage of the cereal flakes, some of the exit air from the drier is recycled back to mix with the the moist fresh air. For each 1000 kg/hr of wet cereal fed to the drier, calculate the input of moist fresh air in kg/hr and recycle rate in kg/hr. The available data on stream compositions is (fractions): For water: Fresh air: 0.0132 Wet cereal: 0.200 Exit air: 0.263 Dried Cereal: 0.050 Air entering Dryer: 0.066
An environmental study was performed to measure the transport of a DDT (a banned pesticide) throughout the globe. A lake in northern Canada was sampled to see if low levels of DDT were present there in spite of it not being administered within 1000 miles of that location. 1.000 L of the lake water was spiked with 100.0 uL of a 2.451 ug/L solution of tetrachlorobenzene, which acted as the internal standard. The entire 1.000 L spiked solution was concentrated onto an SPE column. After washing the SPE column with ~5 mL of pure water, the analyte and internal standard were eluted from the SPE column using ~5 mL of CH2Cl2 solvent. The eluted sample was evaporated under a stream of nitrogen to a final volume of 1.000 mL. 1 uL of this final solution was analyzed using GC-MS, and gave a signal of 24835 for DDT and 11597 for tetrachlorobenzene. To calculate the response factor, a standard solution was prepared consisting of 1.482 ug/L of DDT and 2.451 ug/L of tetrachlorobenzene.…
