A process stream consisting

 A process stream consisting of solvent A with a flow of 3500 kg / h must be evaporated at a pressure of 5 bar

so that a saturated steam is obtained. The process stream maintains the temperature at 20 ° C. Determine the heating effect

which must be added to the process.

Other information:

cp (liquid) = 2.5 kJ kg-1 K-1

Steam generation heat at the boiling point of the solvent 5 bar: 900 kJ / kg

For substance A, the following parameters apply to Antoine's equation:

A = 15.9008 B = 2788.51 C = -52.36

Antoine's equation:

NOTE! The vapor pressure is given in mmHg (1 bar = 760 mmHg), the temperature in
