Purified hci gas is absorbed in water to produce 25 wt% aqueous hci solution. the absorber works continuously at steady-state conditions using cooling water to maintain the temperature of the product stream. the temperature of the feed hci gas is 125°c and that of the feed water is 25°c. the product (exit hci aqueous solution) is at 38 c the cooling water does not mix with the hci solution. (a) draw a schematic diagram of the absorber showing all material streams with their temperatures (where given). 3 marks] (b) calculate the material streams of the feed water and hcl required to produce s0 kg of the product per hour. show the results in kg and moles. [4 marks] (c) 1 mark] write the equation of the energy balance in the general form. calculate the specific enthalpies (per mole) of the feed water, hci feed gas and the hcl product solution. (d) 6 marks) calculate how much heat must be removed from the absorber to produce 500 kg solution per hour. (e) [6 marks] the heat capacity of the product solution is approximately 2.7 j g1c. you can also use data from tables q4(a), (b) and (c) below. table q4(a): heat capacities of compounds cx 10s 0.9715 0.7604 -133.88 bx 10 -0.134 0.688 47.12 temp c compound hydrogen chloride hci water formula state gas a 29.13 33.46 18.296 c h2o h20 gas liquid k equations are in the form c -a+bt+ct2 water are j mol1 k1 or j mol °c1 (see column temp.) units for table q4(b): heats of formation of compounds at 25°c and 1 atm compound aft, kj. mol state liquid -157.75 hydrogen chloride aqueous solution hydrogen chloride water water -92.31 241.83 -285.84 gas gas liquid table q4(c): heats of solution of hci (gas) in water at 25°c and 1 atm heat of solution ah jg (mol hci) moles of water added to 1 mol hci sol -26225 1 48818 2 -56851 -61202 4 -64047 8 -68231 10 -69486
