Ethanol can be produced commercially by the hydration of ethylene: Some of the product is converted to diethyl ether in the side reaction The feed to the reactor contains ethylene,steam and an inertas. A sample reactor effuent gas is analyzed and found to contain 43.3 mol% ethylene, 2.5% ethanol, 0.14% ether, 9.3% inert and the balance water. (a) Take as a basis of 100 mol of the effluent gas, draw and label a flowchart, and do a degree-of-freedom analysis based on atomic species to prove that the system has zero degrees of freedom. Calculate: (b) The molar composition of the reactor feed, (c) The percentage conversion of ethylene, (d) The fractional yield of ethanol (e) The selectivity of ethanol production relative to ether production.

    1. Ethanol is produced by the hydration of ethylene. Some of the ethanol product is converted in an undesired side reaction to diethyl ether and water. C2H4 (g) + H20 (1) → C2H5OH (1) 2 C2H5OH (1) → (C2H5)20 (1) + H20 (1) The feeds to the reactor are ethylene gas and liquid water, each @ 25°C, 1 atm. A sample of the reactor effluent is analyzed and found to be 15°C and contain 43.3 mol% ethylene (g), 2.5% ethanol...

    Synthetically produced ethanol is an important industrial commodity used for various purposes including: as a solvent (especially for substances intended for human contact or consumption); in coatings, inks, and personal-care products; for sterilization; and as a fuel. Although a great deal of attention has been given to the production of ethanol by fermentation of sugars, industrial ethanol is a petrochemical synthesized by the hydrolysis of ethylene: CzH4 (9) + H20 (v) = C2H5OH (V) Some of the product is converted...

    1. Acrylonitrile is produced by the reaction of propylene, ammonia, and oxygen C3H6 + NH3 + O2 ​ C3H3N + 3H2O The feed contains 10 mole% propylene, 12% ammonia, and 78% air. A fractional conversion of 30% of the limiting reactant is achieved. Determine which reactant is limiting, the percentage by which each of the other reactants is in excess, and the molar flow rates of all product gas constituents for a 30% conversion of the limiting reactant, taking 100...

    10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
