Petrochemical

Hi,
Peenal here I am a process engineer in a speciality chemical industry I have found this site extremely useful hence frist of all kudos to all the members who have contributed for this site.Recently I have search this site for books on scale up techniques from pilot plant to plant level but unable to do so.Hence I request our esteem members to please help me and other similar engineers.Any article on scale ups would also be useful.
Regards
Peenal Kumar
