Question: An 8-molar hydrochloric acid solution [SG = 1.12, Cp = 2.76 J/ (gC)] is produced by absorbing hydrogen chloride [HC1 (g)] in water. Liquid water
An 8-molar hydrochloric acid solution [SG = 1.12, Cp = 2.76 J/ (g∙°C)] is produced by absorbing hydrogen chloride [HC1 (g)] in water. Liquid water enters the absorber at 25°C and gaseous HCJ is fed at 20°C and 790torr (absolute). Essentially all of the HC1 fed to the column is absorbed. Take one liter of product solution as a basis of calculation.
(a) Estimate the volume (liters) of HC1 that must be fed to the absorber.
(b) Estimate the heat (kJ) that must be transferred from the absorber if the product solution is to emerge at 40°C.
(c) Estimate the final solution temperature if the absorber operates adiabatically.
