Perhaps the most popular industry among Chemical Engineers is Oil and Gas..I'm not sure with the upstream industry (drilling, exploration and etc), in the downstream industry (petroleum refinery, petro-chemical product production) there are more requirement for chemical engineers, besides oil and gas, chem engineers can also go to food industries, chemical production plant, bio chemicals, waste management, some of chem eng graduate involve the design of chemical production plant system like process flow, piping system, pumping, chemical reactor, and system for other process like evaporation, distillation and extraction etc etc..

As a chemical engineer, you can also take part in research position especially in advance material development, nanotech and etc. But, this research mostly still under nanotechnology, material engineering and chemistry. maybe Chemical engineers might concentrate more on the production.

Chemical engineers' demand is increasing with the growing trend of industry. So, if u think of chemical reaction in large scale production point of view, like to think of the process method of the series of reaction, Chemical engineering's right for u.

I'd suggest you to do more homework on what's the difference between chemist and chemical engineers.
