Well back to work. I am in charge of doing heat integration for the design of a hydrogen plant. There are 7 units in total and each of us are required to write about 30-40 pages of report on the unit design. After which, we will need to do other things like cost analysis, safety health and environment, regulation issues, control systems, pipings et cetera. Past year reports are all around 350-400 pages..darn.. another thing is, the 6 of them are designing only for a single unit. however for me,i need to design a lot of heat exchangers each varying in design. also i cant do anything much until they have all finished designing their own units and then integrate them all together.

This is how a student sees a heat exchanger...

This is what it looks like in real life.. some looks like a mini truck or amoured vehicle

some looks like a torpedo...

some looks like a space shuttle...
It can cost millions just to build one exchanger so as to save on utilities as you are transferring heat from a stream that needs to be cooled to another stream that needs to be heated without any external load. if i design that space shuttle or torpedo-like heat exchanger out ah, i will get murdered...
