A lot of people will tell that chemistry works on the scale of a lab (think test tubes and flasks) and Chemical engineers will work on industrial scale. This is an approach, but is not precise and is misleading. Chemistry is a science not based on a scale. Atmospheric Chemist often works with dimensions bigger than the whole industry and it's unit operations combined, Astrochemist work on analyzing the composition on a whole planet, Industrial chemist work often in pilot plants that are certainly not on the scale of a lab (and yes, they may work on the issues of mass transport, heat transport, and more), NASA Chemists need to think what material is the proper to synthesize for a new spaceship (the the dimensions count here), and environmental chemist often work to analyze or clean pollutants in (at least) an area the size of a portion of a big beach. The inverse is also true. Chemical engineers also work in test tubes to checkout new materials, and to see is a material might work for a process. So then what is the difference? 2 mainthings: the training, yes. And the focus- some might say is the design. Keep a something in mind: Some Chemist may design. But they design instrumental methods to determine materials and others devices that doesn't take into account THE UNIT OPERATION for a process (at least not typically). The UNIT OPERATION is a division for requirements with specific parameters and processes to complete a crucial part in the industrial scale manufacture of a good (a good can be for example ethanol, and the unit operation that includes the design of the distillation tower and mass and heat transfer sequences that comes with the devices made for this, and this is just a simple example). Industrial Chemist analyze a process to see the chemistry of it, not typically to design the unit operation of such a process. Chemical engineers are the ones that (typically) design taking into account the complete unit operation for a given process. But then, if the Unit operation is the main focus of the chemical engineer, what is the thing that make us recognize that the chemist is not an incomplete Chemical Engineer? Well, the answer to this is that the main focus of the chemist is to design new molecules and instruments considering only the molecule of interest or the category of molecules to check, measure, change or affect it. So in a sense, to make a new molecule, if you had to choose between them, and you don't know who is smarter, and are forced to evaluate with credentials only, at first glance, you take credentials into account and you'll put A chemist as a director for developing a new molecule for a given use and may put Chemical engineers as part of the staff- BUT, Using the same conditions and reasoning, if you want a process, you'll put a Chemical engineers as a director and in this case the Chemists will be part of the staff. Keep in mind, this an hypothetical case, and in real life even people without those degrees have ended directing a process and directing the making of a new compound (the chances are less, thou). So, about chemical engineers and chemist- In a sense, they have a bond, but are not the same. You can jump from one to the other but require a couple of coursework. Chemical Engineering is more physics and math oriented than Chemistry. With Chemistry you'll be dealing with chemical knowledge and info regarding particular compound types and principles- but you'll end up taking Physics and Calculus (at least up to multiple integrals) with both and you'll take chemistry (as a science) very serious with both (no special coursework to accommodate you). Facts to consider are that Chemical Engineers are better paid on average, but many things have to be considered here (is not that simple). Yet, Chemical engineering requires more specific credits to be finished. Keep in mind the reason I put education info in here is be cause education is one of the main distinctions for these two professions. Hope this helped.
