Terephthalic Acid. (TPA) is produced by the reaction of p-Xylene. ,(PX) and Oxygen in the presence of a catalyst and solvent (S): Process conditions are provided for the Air entering the reactor and the reactor off gas. A flow chart of the process is shown: Off gases: PX=p-Xylene 4O mol% 96 mol% For 100 kmol TPA produced per hour, draw and label a flow chart the process. In addition to the process provided in the above flow sheet, Additional variables and relationships are defined. They are shown separately here for clarity
From among the following, choose one which is not an exothermic process. 1. Ammonia synthesis 2. Methanol synthesis
Regardless of your answer in part (b), your supervisor instructs you to add 0.2 moles of normal octane per mol of solution. This new stream is flashed and the vapor and liquid streams are separated. The available information for the streams in the..
The composition of a gas derived by the gasification of coal is, volume percentage: carbon dioxide 4, carbon monoxide 16, hydrogen 50, methane 15, ethane 3, benzene 2, balance nitrogen. If the gas is burnt in a furnace with 20% excess air, calcula..
Tris (pentafluorophenyl) borane, commonly known by its acronym BARF, is frequently used to initiate polymerization of ethylene or propylene in the presence of a catalytic transition metal compound.
The heat capacity at constant pressure of hydrogen cyanide is given by the expression Cp[J/(mol ·°C)] = 35.3 + 0.0291T(°C) (a) Write an expression for the heat capacity at constant volume for HCN, assuming ideal gas behavior.
2. Alcohol is a diuretic agent, which increases urine production by reducing water reabsorption. Normal rate of water reabsorption is about 124 ml/min. Assume that the effect of alcohol on water reabsorption (in ml/min) is given by the following equa..
A scheme for concurrently heating separate water and air streams involves passing them through and over an array of tubes, respectively, while the tube wall is heated electrically. To enhance gas-side heat transfer, annular fins of rectangular pro..
