P. V Danckwerts
Education: Winchester College; Balliol College, Oxford University; Massachusetts Institute of Technology. BA (chemistry) Oxon, 1938; SM (Chemical Engineering Practice), MIT, 1948; MA Cantab 1948. Held a post in the small chemical company of Fullers Earth Union Ltd, Redhill, 1939-1940.
Requirement for ChemE Education
Versatility Be Practical
Use fundamental theories and knowledge to solve practical problems
Multi-scale analysis and Synthesis
Analysis of complex system Comprehensive usage of a broad range
of knowledge
Chemical Reactor: Definition
General:
An equipment or device that serves to conduct chemical reactions, i.e. convert molecules from one form to another
Whether you believe you can, or
whether you believe you can’t, you are
absolutely right!
Henryl use the phrase of Chemical Engineering Science to mean the aspects of science developed by chemical engineers for their own purpose in field not covered by other branch of technology.
Narrowed:
Chemical conversion is performed for the purpose of producing or eliminating pre-determined molecular compound(s)
• Purpose: making or eliminating • Control: safe, selectivity, performance
Engineering & Engineer
Quantitative reasoning
Readiness to face open-end question
A habit of visualizing the solution
Invent
Hamlet was created; The telephone was invented; Structure of DNA was discovered
Chemical Engineering
Unit Operations Transport processes Reaction Engineering
……
Applications
Energy Inorganic Industry Petrochemicals
Biochemicals Pharmaceuticals Materials Electronics
Trends in ChemE and Chem. Industry
Globalization:
Competition Job Security
• The ability to find another job
Speed is the key
Sustainability: energy and environmental
