Chemist vs Chemical Engineer (Lec008)

Let's talk about several areas which are comparable to chemical engineering the first one of them is the chemist so I got plenty of people wandering or asking what's the different between a chemist and a chemical engineer well the chemist is more into chemical chemistry the study of actual substances creating new ones and etc and chemical .

Engineers are more in the production of those materials so let's check it out I like comparing chemists will typically use milligrams grams because they are always working in the lab whereas engineers who are working on the plants they are producing kilograms tonnes etc also because they are working small environments they require high purity .

They use it last words whereas we engineers use steel we need to move large amount of materials glassware is not enough they are considering microstates whereas we consider macro States and this is essentially chemistry versus engineering you will also be working with lab codes you can see these essentially glassware .

Etc whereas the engineers work with helmets maybe some ear protection protection this will be much more protective than a lab coat and so on now what's the goal of a chemist is essentially to create science new knowledge maybe they are wondering new molecules how they want to understand how chemicals interact between each .

Other they want to see the physical and chemical properties they use plinth lab experimentation they are most of the time in a lab or chemical laboratory and they work with small scales so that's interesting because many times you see that something works in the lab and you want to scale it up and it won't work so that's the main difference and that's .

One of the tasks of the engineer maybe the chemist has found out a new product and the engineer will be with the task on scaling up that process now what are the topicals you will see as a chemical engineer you will see plenty of general engineering some theoretical basis like mass balance energy balance thermal transport .

Phenomena apply operations such as unit operations reactors heat exchangers pumps distillation columns absorbers fractionation refinery etc and you will be working with the saying or operation of chemical plans of unit operations helping processes automation control etc so what do you think chemistry is essentially general science or maybe .

Even nuclear science quantum science you will see plenty of theoretical chemists and plenty of experimental labs you will be working on creating or working with biology maybe even some bio stuff nanotechnologies in a increasing area and they are also wandering on new technologies so from is too easy you want to be working with machines and .

Loads of products or you want to be working with small scale and be creating new materials well I got these two memes so essentially is one is in favor of engineering the other one is in favor of chemistry and I think both have reason so in chemistry they say a plus B equals C and D but in real life you will require maybe you want to separate age .

You need to cool down B then react them and you need to preheat them and then react them and eventually separate C and D and cool down use recycle very much much more complex processes yet the reaction or the idea the same and the chemist or the chemist will have this so in chemical engineering you will have very .

Simple stuff a plus B convert to C and D you get this into a machine or into a plant but they will be loving to see how they interact the monomer how the using radicalization how the oxygen donates the electrons how there is resonance and so on much more technical stuff they will make fun of us because this is so simple yet there are .

Different fields what do you like the most designing and operating a plant or wondering and chemical reactions and this is another example in which you will see a chemist and a chemical engineer this is very very landing or you will see very how they differ now one will be in analyzing the reaction .

And the other one will be in the reactor so the chemist is studying kinetic reaction how do they the reactants react how fast how do they are the exothermic or endothermic do they require cooling or heating or must the reaction be adiabatic they want to see how can they improve the kill the conversion maybe they want to increase selectivity also .

This is very chemical the chemistry and the engineer will be willing to work with the chemist and ask him okay give me all the knowledge all the science because I'm going to be working with machines I want to design the reactor I want to see what do I need to operation maybe I want to see the utility the cost I want to see what are the raw materials .

How much are we going to need in heating cooling for the plant and so on so you can see guys they are working on the same one is analyzing the reaction and the other one is analyzing the react you
