Feed gas containing of 78.5mol % H₂, 21% of N₂ & 0.5% of Ar is mixed with recycle gas and enters a reactor where 15% N₂ is converted to NH3 as per the reaction. Ammonia from the exit of the reactor is completely separated from unconverted gases. To avoid the buildup of inerts, a small fraction (5%) of the unreacted gases purged and the balance recycled.

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 9.0 mole% methane in air flowing at a rate of 7:00 x 102 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 mole% O2 and 79% N2 and to have an average molecular weight of 29.0.)
Q4/in a two stage process, acetic acid (A)is extracted from water (W) into hexanol (H) in a liquid-liquid extraction vessel and the extract is subsequently separated by distillation. Assume that water is completely insoluble in hexanol. A mixture of 18wt% acetic acid and the balance water is feed to liquid-liquid extraction vessel. Pure hexanol is feed to the column to extracted the acetic acid. The water-rich stream leaving the vessel is 99.5wt% water and the balance acetic acid. The hexanol-rich extract from the vessel is feed to a distillation column. The composition of the distillate is 96wt% acetic acid and the balance hexanol. The bottom stream contains 97.2wt% hexanol and recovers 95% of the hexanol feed to the liquid-liquid extraction vessel. Calculate the percentage of acetic acid in the process feed that is recovered in the distillate stream. Distillation Liq-liq Column Extraction

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.
Nitrogen is to be liquefied in a simple Linde process. The feed and recycle are mixed. compressed to 64 bar, and precooled to 135K. The vapor then passes through a heat exchanger for additional cooling before beinng throttled to 1 bar. The unliquefied fraction leaves the seperator at the saturation temperature and passes through the heat exchanger, then exits at 120 K. a. What fraction of the gas is liquefied in the process? b. What is the temperature of the high pressure gas entering the throttle valve?
