In a process producing KNO3 salt, 1000 kg/h of a feed solution containing 10 wt% KNO3 is fed to an evaporator, which evaporates some water at 422 K to produce a 50 wt% KNO3 solution. This is then fed to a crystallizer at 311 K, where crystals containing 98 wt% KNO3 are removed. The saturated solution containing 37.5 wt% KNO3 is recycled to the evaporator. Calculate the amount of the recycle stream R in kg/h and the product stream of crystals P in kg/h.

Photosynthesis is a process that incorporates carbon dioxide and water and yields food in the form of glucose (CGI-11206) for the plant with oxygen (02) as the by-product. In a (5) five minute period a tree consumes 45 grams of water and 60 grams of carbon dioxide in this process. Determine the limiting reagent, the excess reagent and the amount remaining of the excess reagent, and the amount of glucose produced, (Show all work for each section) (This is a limiting reagent problem). Determine the amount of glucose produced
Sea water containing 4 wt. % salt (NaCI) is passed through a reverse osmosis (RO) membrane filtration unit to produce a "fresh" water product containing 0.5 wt.6 NaCI and a concentrated brine waste stream. If there are 28 kg of fresh water recovered from every 100 kg of sea water, then determine the concentration of the brine waste stream. Type your answer in as a weight percentage rounded off to one decimal place, but do not include the 6 symbol.
8. 9. butane is consumed, and the product gas contains 9 mol CO2 per mol CO. Calculate the molar flow rate of water in the stack gas. Butane is completely burned in a process fed with 25.0% excess air. Based on 1 mol/h of butane, determine the composition in mole fractions of oxygen in product stream. Methane at a molar flow rate of 55 mol/min is burned with dry air. A partial analysis of the exit gas reveals that the mole fraction of nitrogen is 0.85 on a dry basis, and the molar flow rate of the dry exit gas is 600 mol/min. P

Q3/ A 100 mole feed containing equimolar amounts of methanol and water is mixe with 10 moles of a 40 mole% aqueous methanol stream. The mixture enters a distillation column that creates two streams. A top stream exits that contains 70 mole% methanol and balance with water. The bottom stream, which is 70 moles, enters a second distillation column. A top stream exits the second column as a 50% methanol and 50% water. The two top streams exiting the distillation column have the same flow rate. Calculate all unknown streams variables.

Methanol (CH3OH) is produced in the reaction of carbon dioxide and hydrogen via the reaction and process given below: CO2+3H2→CH3OH+H2O The fresh feed to the process contains hydrogen, carbon dioxide, and 0.400 mol% inerts (I). The reactor effluent passes through a condenser that removes essentially all of the methanol and water formed and none of the reactants or inerts. The unreacted reactants and inerts are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. 100 mol/h of feed to the reactor (not the fresh feed to the process) contains 29.5 mol% CO2, 68.0 mol% H2, and 2.50 mol% inerts. The single-pass conversion of hydrogen is 46.71%. What is the recycle-to-fresh feed ratio?
