Elementary Principles of Chemical Processes

**paperback** I believe this is the exact same book as the one imaged on Amazon with the ISBN 978-0470616291. However, the ISBN in my book is 978-1119177647, which is not found on Amazon. I believe its just a special cover for my university. If there are any issues, I will glady offer a refund. Its seems to be exactly the same though, 4th edition.
