The feed to a separation process contains 50 wt% benzene, 30 wt% toluene, and 20 wt% xylene. The feed enters the process at a flow rate of 100 kg/h. The overhead stream from the first unit contains 95 wt% benzene, 3 wt% toluene, and 2 wt% xylene. The overhead stream from the second unit contains 3 wt% benzene, 95 wt% toluene, and 2 wt% xylene. The flow rate of the overhead from the first unit is 52% of the fresh feed flow rate. The amount of benzene in the overhead from the second unit is 75% of the benzene that enters the second unit. Determine the flow rates for all of the streams leaving both units.

A distillation column should separate benzene and toluene in a 30 t/h feed flow containing 40 % benzene and 60 % toluene. The overhead product should be 97 % benzene and bottom product 98 % toluene. The molar reflux ratio RD = 3.5 and the saturated liquid feed has a boiling point of 95 °C. Calculate flow rates of distillate and bottom product . determine the number of ideal trays needed for the separation . Where is the feed tray...

A stream of hydrocarbons contains 80% by weight hexane and 20% benzene point it is desired to recover the benzene from this stream using an extraction process. The extraction is achieved by feeding the hydrocarbon stream and a stream of pure solvent, called "sulfonate". The "sulfonate" extracts a high percentage of benzene but not hexane. At the exit of the extract two streams come out: one with 95% hexane and 5% benzene, and the second stream brings the solvent and...

Separation Process: Suppose a saturated liquid feed of a benzene (B)/toluene (T) mixture (50 mol% B) to a column is to be separated into a high purity distillate that is has a mole fraction of B equal to 0.9999 with a bottoms product mole fraction of 0.10. You may take the relative volatility to be aBT = 2.49 at the temperature that the column is operated. You are also given the reflux ratio to be 10.0, assuming a total condenser....

A liquid mixture contains 50 wt% ethanol (E), '10 wt% of a dissolved solute (S) and the balance is water (W). A stream of this mixture F, is fed to a continuous distillation column operating at a steady state. Two streams emerge from the column as the top product, P and the bottom waste Q, respectively. The column design class for the product streams is to have equal mass flow rate, and for the top product stream, P is to...

An isothermal flash unit is to be used for the separation of any mixture into liquid and vapor streams at equilibrium. The composition of the streams depends on the quantity of the feed vaporized (flashed). If the vapor-liquid equilibrium relationship is expressed in terms of equilibrium constants; develop the mathematical model and calculate the portion of vapor stream to the feed stream, f=V/F using Bisection method just 3 iterations. The compositions in the feed (zi) and equilibrium constants at this...

Fresh apple juice contains 75% water flowing at a mass flow rate of 200 kg/h. The fresh juice is concentrated in an evaporation process. A portion of the fresh feed is bypassed to meet the evaporator maximum capacity. The bypass stream joins the evaporator outlet stream. Ninety percent of the water entering the evaporator is evaporated. The concentrated apple juice contains 25% water. Draw the process flow sheet and calculate the mass flow rates of produced and evaporated streams. provide...

Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor. The fresh feed to the process contains 32.0 mol% CO, 64.0 mol% H2 and 4.00 mol% N2. This stream is mixed with a recycle stream in a ratio of 4.00 mol recycle / 1 mol fresh feed to produce the feed to the reactor, which contains 14.0 mol% N2. The reactor effluent goes to a condenser from which two streams emerge: a liquid product stream containing essentially all...

Seawater containing 3.50 wt% salt passes through a series of 9 evaporators. Roughly equal quantities of water are vaporized in each of the 9 units and then condensed and combined to obtain a product stream of fresh water. The brine leaving each evaporator but the 9th is fed to the next evaporator. The brine leaving the 9th evaporator contains 4.70 wt% salt. It is desired to produce 1 x 104 L/h of fresh water. 1)How much seawater must be fed...

A stream of hot dry nitrogen flows through a solvent recovery unit that contains liquid benzene. A substantial portion of the benzene vaporizes in the unit and is carried off by the nitrogen. The combined gases leave the unit at 150°C and 1.2 bar and enter a condenser in which a portion of the benzene is condensed. The remaining gas leaves the condenser at 20°C and 30 bar. The partial pressure of benzene in the feed to the condenser is...
