- An 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.In the Deacon process for the manufacture of chlorine, HCl and O2 react toform Cl2 and H2O, Sufficient air (21 mol% O2, 79% N2) is fed to provide 35% excess oxygen and the fractional conversion of HCl is 85%. (a) Calculate the mole fractions of the product stream components, usingatomic species balances in your calculation. (b) Again calculate the mole fractions of the product stream components,but use the extent of reaction in the calculation.Jansen Gas creates three types of aviation gasoline(avgas), labeled A, B, and C.

- Chlorodifluoromethane (CHF2Cl) was widely used in the compression/cooling circuits of refrigeration or air-conditioning systems. Since the discovery that such compounds (HCFCs and CFC's) released into the atmosphere were a major cause of depletion of stratospheric ozone, newer refrigeration systems make use of certain hydrofluorocarbons (HFCs), which are degraded in the lower atmosphere, instead. Often, mixtures of such compounds are used. Suppose a sample of refrigerant gas consisting of a simple mixture of the gases pentafluoroethane (C2HF5) and difluorormethane (CH2F2) has a density of 3.06 g/L at 14 °C and 0.974 atm.

- - 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.In the synthesis of hydrocarbons, the carbon source is carbon dioxide. Although the CO2 concentra?on in the atmosphere raises at a drama?c speed, point sources are probably the easier sources for a PtX process. Iden?fy 3 possible point sources, explain why CO2 is formed and what challenges each of the three CO2 streams presentsPotassium dichromate has several industrial applications. To determine the purity of the salt that will be used in different industrial processes, a sample mass equal to 2.660 g was dissolved and quantitatively transferred to a 500.00 mL flask. An aliquot of 25.00 mL of this solution was treated with excess KI and the released iodine was titrated with 0.1000 mol L-1 sodium thiosulfate, spending 27.00 mL. Calculate the purity of the analyzed salt. Data:K = 39.10 O = 16.00 Cr = 52.00 I = 126.9 S = 32.07
