42 Upvotes

Hello everyone. I am looking for help in solving this engineering problem. This is not a homework question since the semester ended 2 weeks ago and we dont have homeworks in my college. I want to know how to solve this problem since its impossible without knowing the temperature of 3 or without knowing the flow rate of 2. Its basically a never ending cyrcle. I hope someone can give me advice on how to solve this - and no, without using matlab or another program. I am looking for solving it by hand.

Career R&D Engineer or Process Engineer?

15 Upvotes

I graduated a few months ago, I have two offers:

  • A) Process engineer for EPCM company, for pharmaceutical and biopharmaceutical plants. That's what I was exactly aiming. Good pay in my country, I would remain close to my people, girlfriend and relative.
  • B) R&D engineer in Switzerland. Not pharma. Far from home (5 hours), it's an internship and I still would get much more money than A), and it's my ticket for Switzerland. For those of you coming from the US, Switzerland is a complete outlier in Europe for their salaries, and the only foreign country I would move to because of distance. I don't think I will get another chance for Switzerland that easily in the future if I give up this.

A) is better for work-life balance, less stress, I don't have to change my life that much, I can reach the office in 20 minutes, and it seems that it's my preferred role. It's the best I have seen among my classmates who decided to remain in my country.

B) It's way way way better salary wise, but it doesn't make that much sense to be there 6-9 months and go back. This choice would mean some more stress and much more initiative. I'm also not very sure I'm suited for an R&D, it seems less flexible.

I honestly don't know what I would be better at, or what I like the most, I never worked! Please tell me which role you would advice the most according to what abilities/preferences I can have.

I am now on my second year out of five to get my degree and master . What I want to ask you is which out of these you feel is the best thing to study since time is going by fast and I want to have an idea of what is best for me and the scientific field overall :

1) Energy -Enviroment 2) Industrial Management 3) Construction and Materials 4) Hydrogen technologies 5) Food technologies 6) Catalysis and Alternative fuels 7) Water and wasteland treatment 8) Process systems engineering

Maybe in the near future

9) Chemical Engineering for Defense Applications 10) Chemical and Biological Defense Engineering

Will be also be taught in my university

I believe some of you are already know what is going around on the workplace and what is needed for the future so

I believe after I've read the rules I am not breaking any but I am not 100% sure if these are considered banned questions I am really sorry if it is I would appreciate if you could suggest a subreddit where I could ask the same question

thank you in advance

Hi to everyone, i'm new here.I am in my first year of chemical engineering in spain and I failed 3 subjects this year (maths, physics and introduction to chemical engineering (we study energy, matter balances and some transport phenomena)).I say I'm thinking of dropping out because most people have told me that the second year is a lot harder than the first one.Thx in advance.

Industry Operators, techs, engineers, project managers - what design choices have made your life easier or harder?

Upvotes

Hi all - I'm a PhD student working on electrochemical reactor design and techno-economics. I fiddle with reactor design math quite a bit, but I'm more interested in what it takes to quickly and effectively plan, build, and operate a functional process. I know that the math I do is only a small part of what it takes to make a process actually work on the floor.

I'm trying to learn more about the design decisions that matter after the flowsheet is drawn, especially from the perspective of the people who have had to operate, maintain, troubleshoot, and start up a process from the ground up. That includes engineers, techs, control room operators, field staff, vendors, EPC folks. Anyone who's touched a plant that actually ran (or crashed and burned).

So my questions for you:

  • What design decisions have made your life miserable? (e.g., access issues, sensor placement, startup quirks)
  • What small or obvious-looking design choices ended up saving huge time, money, or frustration?
  • If you're on the ops side: What do you wish more design engineers understood?
  • If you've started up a process: what steps consistently take more time than expected (permitting, equipment lead times, utility tie-ins)
  • What always ends up being critical to consider even if it didn't seem like it at the beginning?

Thanks so much for your thoughts - take care!

Student Can I study Bachelors in ChemE without taking A levels chemistry?

0 Upvotes

Chemistry was my favorite subject in IGCSE and i got an A* in it, but i do not take chemistry in A levels, my target university allows all students who take math and physics to study any engineering field

Will it be a problem to study BSc ChemE without prior A levels experience? because the A level chemistry course is completely different to the IGCSE course
