A caustic solution entering the shell - tube evaporator at 1 0 0 0 0 kg / hr with a temperature of 1 0 0
A caustic solution entering the shelltube evaporator at kghr with a temperature of C is concentrated in a single effect continuous evaporator into a concentrate of sugar solution. The concentrated stream leaves the evaporator at kghr The vapour space inside the evaporator is at kPa g Steam is supplied at kPa abs into the shell side. The overall heat transfer coefficient HTC is WmK
