- An 11.5 wt% mixture of acetic acid in water is to be extracted with 1-butanol at atmospheric pressureand 25°C in countercurrent operation. We desire outlet concentrations of 0.5 wt% in the water and 9.6wt% in the butanol. Inlet butanol is pure. Find the number of equilibrium stages required and the ratioof water to 1-butanol by using the McCabe-Thiele diagram design method. The acetic acid equilibriumdistribution is given by K = 1.613 (wtfr. in butanol/wtfr. in water). Required steps:a. Convert the streams and equilibrium data to mass ratio unitsb. Plot the equilibrium curvec. Plot the operating curve to determine the water to 1-butanol ratiod. Step off the equilibrium stages- The major objective of a roasting process is to eliminate the Sulphur contained in the concentrate andto provide a calcine. In a roasting plant, 1000 kg per hour of molybdenum(IV) sulphide (MoS2) is roastedwith 25 % excess air to obtain MoO3 calcine in a chamber-type roasting furnace. Preheated air entersthe reactor at 400 K while MoS2 enters at room temperature. After the process, the waste gases leavethe reactor at 1000 K, and the calcine leaves at 850 K.a) Draw process flowsheet and heat balance diagram (ref. temp is 298 K) b) Calculate the amount of off-gas per hour in moles. c) Calculate the amount of calcined MoO3 per hour in kg.Isomerization of paraffins is carried out to increase the octane number of a hydrocarbon. The reaction takes place over a fixed bed of catalyst under mild temperature and pressure. a) Sketch a labelled flow diagram of BP paraffin isomerization process. Your sketch must include a reactor-separator-recycle systems. b) Briefly describe the process of paraffin isomerization.
- Show steps plsPlease answer atleast 4 sub-parts. Thank you.Pls do fast within 5 minutes and i will give like for sure Solution must be in typed form To plan a liquid–liquid extraction we need to know the solute’s distribution ratio between the two phases. One approach is to carry out the extraction on a solution that contains a known amount of solute. After the extraction, we isolate the organic phase and allow it to evaporate, leaving behind the solute. In one such experiment, 1.235 g of a solute with a molar mass of 117.3 g/mol is dissolved in 10.00 mL of water. After extracting with 5.00 mL of toluene, 0.889 g of the solute is recovered in the organic phase. If we extract 20.00 mL of an aqueous solution that contains the solute using 10.00 mL of toluene, what is the extraction efficiency?

EX _____ ETAn aqueous waste stream that has a maximum concentrationof 0.50 M H₂SO₄ (d=1.030 g/mL at 25C) will be neutralized by controlled addition of 40% caustic soda (NaOH; d=1.430 g/L) before it goes to the process sewer and then to the chemical plant waste treatment facility. However, a safety re-view finds that the waste stream could meet a small stream of animmiscible organic compound, which could form a flammable vapor in air at 40.°C. The maximum temperature of the causticsoda and the waste stream is 31°C. Could the temperature in-crease due to the heat of neutralization cause the vapor to ex-plode? Assume the specific heat capacity of each solution is 4.184 J/gK.
