Question

A single effect evaporator is used to concentrate a dilute stream of sugar syrup containing 15% dissolved solids to 45% solids. The feed stream enters the evaporator at 391K with feed rate of 2kg/s and vapor exits the evaporator at 1kg/s. Steam is available at a pressure of 270kPa (abs) and an absolute pressure of 153kPa is maintained in the vapor. Assuming a heat transfer coefficient of 2450W/m2K, calculate the following
 List all your assumptions
4.1 Calculate the rate at which the concentrate exits the evaporator. 4.2  Calculate the steam consumption.
4.3 Calculate the heat transfer are required.
4.4 Calculate the steam economy.
