A single-effect evaporator is used to concentrate syrup from 10% to 70% solids. The production rate is 50 kg/h. The evaporation occurs at a pressure of 50 kPa (a boiling point of 81.3°C for pure water). The feed syrup enters at a temperature of 20°C. Energy for evaporation is provided by steam entering as saturated vapor at 200 kPa and exiting as saturated liquid at the same pressure. What steam flow per kg of product is required to accomplish the evaporation if we assume no energy losses?
