A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 6.00 mole% methane in air flowing at a rate of 1300.0 kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. Calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (Note: Air may be taken to consist of 21.0 mole% O2 and 79.0 mole% N2 and hence to have an average molecular weight of 29.0). Required dilution air: Mass percent O2 in product:

1. A wet gas from a field in Iran is processed through two stages of separation; first stage separator operates at 220 psia and 71°F, while the stock tank operates at atmospheric pressure and 69°F. The separator gas condensate ratio is 41,000 scf/STB and the stock tank gas condensate ratio is 450 scf/STB. The molecular weights of the separator gas and stock tank gas are 25.0 and 35.0 lb/lb-mol, respectively. The stock tank condensate gravity is 0.85 and its molecular weight is 125 lb/lb-mol. Let us calculate the specific gravity of the reservoir gas in a step-wise manner, by considering quantities for one STB of condensate. Note that 1.0 bbl is 5.614 ft.

In the determination of molar mass of an unknown substance by ebullioscopic constant, 30 mL of acetone (C3H6O) was placed in a test tube with thermometer and glass tubing and subjected to water bath. Upon boiling, the temperature reads 56 deg C. For the boiling point of unknown-acetone solution, you prepared the solution by mixing 1.60 g of unknown solute in the 30 mL acetone and subjected it again to water bath. The boiling temperature of the solution is 56.68 deg C. The density of acetone = 0.9849 g/mL and the Kb of acetone = 1.67 degC/kg What is the value for delta Tb or the change in boiling temperature (in degrees Celsius)? Final answer must be rounded off to 2 decimal places, and shall NOT have any unit.
It is desired to determine the molecular weight of an organic compound known to be volatile. For this, a glass balloon with a full volume of 152 mL is weighed and the weighing result is recorded as 215 g. Then, the organic compound that is desired to have some molecular weight in liquid form is added into the balloon and evaporated in a water bath until dryness. After the steam temperature is measured as 90 °C, the balloon is left to cool and the organic compound in the balloon condenses again. The balloon is then weighed again and recorded as 215,367g. Find the molecular weight of this organic compound since the pressure of the environment where the experiment is performed is 700 mmHg.

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?

Draw a BFD for a desalination process. This process will vaporize water and condense the vapour to make pure water. Nearly 50% of the water will be desalinated by this process. The remaining water and salt will be cooled by mixing with sea water and returned to the sea.
