(d)Data below shows Industrial Distillation of Methylene Chloride (MVC) and Ethylene Chloride You are required to plot the McCabe –Thiele diagram for the column showing equilibrium data for methylene chloride (MVC) and ethylene chloride, 45o line and also data for operating lines (Enriching and Stripping sections of the distillation column) all on the same plot. From the diagram determine the optimal feed stagefor the column
Can you solve the number 1 and 2 please? Thanks
A mixture of benzene and toluene must be separated using a distillation column with the benzene purity at the top of the column as 92 % and bottom as 5%. The 250 kmol/h saturated liquid feed contains 55 mole% of benzene. The reflux is a saturated liquid and a reflux ratio of 1.9 is maintained. Estimate the distillate, bottom rate, minimum and actual number of stages required to obtain the desired purity. The vapor liquid equilibrium data at operating pressure of 101.3 kPa are given below. x|0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 y 0 0.21 0.38 0.511 0.627 0.719 0.79 0.853 | 0.91 0.961 | 1.0
SEPERATIONS Absorption: Contaminant in a Gas Effluent We are going to absorb 90% of a contaminant in a gas stream containing 15.0 mole of the contaminant by absorntion into a water phase. The total inlet gas flow to the absorption column is 100.0 kgmole/hr and the total water flow is 200 kgmole/hr. Inlet water is NOT pure but contains 0.5% of the contaminant. I he process operates isothermally at 300k and a pressure of 1 atm. The equilibrium for this system is effectively characterized by either a Henry's Law relationship or Raoult's Law (using partial pressure), a general equilibrium relationship that can be used is ya=1.60*xa. plot the operating line and determine the minimum number of stages (graphically) for the equilibrium relationship provided. Confirm the results of part (a) using the analytical Kremser equation.
Chemical Engineering A flotation cell is fed with solids at the rate of 250tph with a pulp having a density of 1.35. Material solid density is 3.2. The concentrate contains 15% of the feed solids mass and it has a pulp density of 1.15. The concentrate solid density is 3.5. How much water must be added to the tails to give an L/S ratio of 1.25. Give your assumptions and continue answering.
1) An evaporator is concentrating solutions coming from three different sources.The first source contains 20% NaCl by weight, the rest is water. The secondsource contains 10% by weight NaCl, 30% NaOH by weight, the rest water. Thethird source contains 25% NaCl by mole, 25 % NaOH by mole, the rest water.The feed streams are fed directly to the evaporator at the following flow rates;100 kg/min for the first source, 7800 kg/min for the second source and 120kg/min for the third source. If 70% of the original water is evaporated, calculate(a) composition in % by weight of the product (b) the flow rate in kg/min of theproduct.2) Two process streams are mixed to form a single stream. Only the flow in themixed stream is known. A soluble salt is added to one of the original streams ata steady rate. Samples taken of this stream show it to be 4.76 % w salt. Samplesfrom the combined stream show 0.62% w salt. What is the ratio of the flows inthe two original streams?3) A chemist attempts to prepare…
A cooling tower works with the amount of cooling water 1 ton/hour. Conditions of cooling water in the cooling tower has a solid content of 1350 ppm. The cooling water entering the cooling tower is processed in such a way that the solids content is a maximum of 225 ppm. If the cooling water evaporated rate is assumed to be 2.5% the cooling water inlet rate, calculate the concentration cycle, the added water rate, and the blowdown water rate!
A stream containing propionic acid and water at 60:40 mass ratio is fed to a mixer at 3 kg/s with pure cyclohexane as solvent. What should be the flow rate of the solvent in order to attain 40:60 mass ratio of solute and solvent in the extract (solvent-rich) stream? Prepare graphical and computational solution.
An evaporation-crystallization process (as shown below) is used to obtain solid potassium sulfate from an aqueous salt solution. The feed contains 18.7 wt% K2SO4. The wet filter cake contains solid sulfate crystals and a 40.0 wt% salt solution. The filtrate is recycled to mix with the feed. The evaporator has a capacity of 175 kg of water evaporated per second. The filtrate has 40.0 wt% salt solution, as well, and from the water entering the evaporator, 45.0% is evaporated. In the wet filter cake, there is 10 kg of the solid crystals for every 1 kg of the salt solution. a.) Calculate the fresh feed rate. (Include units) b.) Determine the production rate of crystal. (Include units) c.) Calculate the recycle ratio. (kg recycle/kg feed) Include units
Example 5.4. Redo the Example 5.2. once again, but consider the case that there is no recycle of the filtrate to be mixed with the fresh feed. Determine (a) the amount of K2Cro, produced per hour and (b) the rate that we need to evaporate water. Without the recycle of the filtrate, we can re-draw the flow chart as shown on the next page. We then try performing the balances around the whole process, as done previously. water vapour mz kg FIlter cake me kg K crystals (100%) makg 36.4% K 63.6% w 100% w Feed m -4.500 kg 33.3% makg 4941 50.6% w Crystalliser & Fater Evaporator Filtrate me kg 36.4%K 63.6% w
