This lecture covers the calculation of heat energy in absorption units, focusing on the absorption of gaseous HCl in water. The instructor explains the heat energy involved in the process, including the heat of solution and mixing at 25°C. Various scenarios are discussed, such as different compositions of HCl in aqueous solutions and the corresponding heat values. The lecture also delves into the energy balance in reactive processes, with examples like ammonia production and sulfur dioxide oxidation. Practical calculations are demonstrated, such as determining feed rates, extent of reaction, and heat transfer rates in different chemical reactions.
