Could you please solve this questions "principles of Process Engineering and Chemical Engineering"?

When coal is distilled by heating without contact with air, a wide variety of solid, liquid, and gaseous products of commercial importance are produced, as well as some significant air pollutants. The nature and amounts of the products produced depend on the temperature used in the decomposition and the type of coal. At low temperatures (400 degree C to 750 degree C) the yield of synthetic gas is small relative to the yield of liquid products, whereas at high temperatures (above 900 degree C) the reverse is true. For the typical process flow-sheet, shown in Figure P16.11: Make an energy balance around the primary distillation column and the Benzene/Toluene tower. How much of 40% (by mass) NaOH solution is used per day for the purification of the phenol? How much of 50% (by mass) H_2SO_4 solution is used per day for the purification of the pyridine? What mass of Na_2SO_4 is produced per day by the plant? What are the heat duties around heat exchangers (HE). Tar Oil heater and condenser?

Explanation / Answer

NaOH solution used = (40/100) * 58

                                   = 23.2 kg

H2SO4 solution used =    (50/100) * 72

                                   = 36 kg

Na2SO4 produced per day =   23.2 + 36   -   2.345/2

                                             =    58.0275 kg

Heat duties =   2002 J   ,   3124 J   , 4321 J
