Ecercise1. Total Area Targeting

 Calculate the values of Q in each interval and estimate the

corresponding area. Use U= 0.001 MW m-2 ˚C

Take under consideration

utilities, which are used in

system:

• furnace (300 ˚C)

•Cooling water (15 ˚C)

Ecercise1. Total Area Targeting

Questions for discussion

 1. Is the total area predicted this way, realistic? That is, is it close

enough to a value that one would obtain in a final design?

 2. Is the estimate, realistic or not, conservative? That is, is it

larger than the one expected from a final design?

 3. How complex is a design built using the vertical transfer?

Ecercise2. Design a Heat Exchanger

Network

∆Tmin = 10K; Q h,min = 40 kW, Q c,min = 60 kW
