5 yrs experience in Sugar Industry what’s next?

Hi, I need advice I’m from the Philippines and I’ve worked in the sugar and distillery industry for 5 years. I am currently a supervisor. Are there other opportunities I can venture to? Both Abroad and here in my country. I’m not sure what industries I can enter aside from where I work now, and if it is still possible.

Question about the Ponchon-Savarit method:

Does the P-S method need 2 graphs to get the number of stages (x-y and Enthalpy vs x graph) or is it only the Enthalpy graph needed. My lecturer told me that you only need the Enthalpy graph but youtube used both the x-y and Enthalpy vs x

Recommendations for self learning separations online

So, basically the title. I’m currently in the middle of my separations course for the quarter and the professor sucks. At least sucks for me. I do better when I can actually practice problems with a little guidance, or see how and why each step is done.

I don’t do well just learning by copying derivations that are copied from the book, and then told to just read the book which doesn’t have any more explanation anyway.

So now I understand that I need to find more resources (actually any resources) that may help explain the concepts, and provide practice problems with some assistance or guidance. There’s no more organic chemistry tutor videos at this point I don’t believe, and other videos I’ve looked up are basically just overviews of concepts. If anyone has any recommendations it would be greatly appreciated. Thank you.

My Career Path: PhD + 10 YOE

A few days ago, there was a post about "Career Path for Experienced Engineers," and I have been thinking about posting a summary of my career up to this point starting with grad school.

Here is a summary of of my career path and thoughts

My Career Path:

Position 1:

Job: Graduate School

Length: ~5 years

Location: P4 School in the Midwest (for non-US people, P4 schools are the "large football schools" in the SEC, Big 10, ACC, Big 12)

Research Area: Using density functional theory (DFT) for catalysis.

Position 2:

Job: Academic Postdoc

Length: ~2.25 years

Location: Different P4 School in the Midwest

Research Area: Development of a hybrid molecular dynamics (MD)/DFT method to understand combustion.

Position 3:

Job: National Lab, Contractor

Length: ~7.5 years

Location: West Coast

Research Area: Using MD for combustion studies

Position 4:

Job: National Lab, Contractor (same lab, different location)

Length: Less than a year

Location: Gulf Coast

Job Duties: I have left research and now working in "Technology Transfer" as a program manager.

My Advice/Notes:

  1. I started my career in computational catalysis and now doing technology transfer (so theory to applications). A PhD doesn't limit you to the research you do in grad school. You will learn a lot of skills that you can apply to other areas. Knowing how to market yourself will open up new doors as you advance in your career.
  2. Every job I have had, I got due to networking. This could be "hey jpc4zd, I know someone who is looking for X, here is their info" to "you need to apply to this job."
  3. Moving sucks, but luckily I have been able to move. My SO is a nurse, which is always in demand everywhere (they started their career traveling nursing, so moving is no problem for them). I know a decent amount of people who have moved to advanced their careers, so it isn't uncommon (my previous program manger went to college in Boston, started work in TN, moved to FL ("overnight") then now on the West Coast).
  4. My transition from research to management has been due to two things (a) having an understanding of how the lab works, and (b) volunteer positions (I'm a volunteer in a few local groups, where I gained the "leadership" experience)
  5. The lab I have been with requires a security clearance. The biggest issue I have seen is weed. Despite what individual states may say, weed is still illegal on the federal level. This applies to multiple labs across the US (think NASA, DOD, DOE) depending on the position.

Career crossroads

I work in a plant setting for a multinational corporation that is an industry leader in their field. Recently interviewed for an internal position but didn’t get it. I’m currently 4 years with this company and is the only professional experience that I have. The job I applied to was basically the same as my current role (long term process engineer) but would be for a new business function. I don’t mind my current role but do feel a bit bored with it at times so figured getting involved in a new process would shake things up. Everything else I’m relatively happy with, colleagues, management, pay, work stress. Getting rejected has been a bit of gut punch, especially since I have all the skills to do the job and interviewed well. I’m considering if I should branch outside and gain some different experience or should I just carryon at my existing company. My family is telling me that working at multiple companies looks better in the long run than just staying at one place and leads to higher pay. Also, the hiring manager just Teams’d me to say I got rejected, if I want to stay in the company, is it obligatory to bend the knee and thank him or can I just ignore his message and move on?

Is $200K Total Comp as New Grad in O&G Possible in 2024?

I read this under the mechE subreddit.

https://www.reddit.com/r/MechanicalEngineering/comments/18er5ep/comment/kcrwfja/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Claim:

"The majors (Exxon, Chevron, Shell, BP, etc) pay lower than the independent publicly traded oil companies. Oil prices were $110/bbl and petroleum engineering placements were 99%. I was working as a petroleum engineer even though I was ME undergrad.

My comp breakdown:

  • $100K base
  • $20K cash signing bonus
  • $20K RSUs
  • $20% YE bonus
  • 401K match
  • Health insurance + dental/ vision + life (paid monthly premiums + $1,000 towards HSA)
  • Relocation package (1 month salary bonus + $8K cash + all moving expenses paid + 90 days company paid apartment while I found a house + realtor fees/ closing costs with home purchase)

TC was a little over $200K for that tax year and I started in April.

After 5 yrs I was over $400K TC. I’m 15 yrs in now and I’m just under $1MM."

Is this even possible??? I've never ever heard of O&G paying this high. I have no experience though. Thoughts?

Quality Assurance Engineer?

Hello,

I have been working as a process engineer for about two years and are looking to change role, mostly due to no job growth in my current role. I have a phone screen interview soon for a QAE role but I realize I don’t know much about it. Does anyone here have experience as a QAE? How is it? And is it considered good to go from a process engineering role to a QAE role?

TIA

Ex-Oil & Gas workers, where did you go after? Did you regret it? Am I overestimating how much the US election will affect the market?

With the election being finished in the US, it seems like my line of work will be expanding, I work as a consultant at an engineering firm for natural gas utilities in the US. For a while now I have been exploring the idea of jumping industries, I never wanted to be in O&G but it’s just where I was able to get a job. It seems like things are probably going to improve in O&G (likely at the expense of the environment but whatever the results are in and we have to continue on). Would I be stupid to leave? Has anyone left and regretted it?

I know that O&G has been pretty volatile, just looking for anecdotes from engineers that have moved around. I am about 3 years into my career at this point, and I plan to get my FE and PE before I leave my current job since I’ve almost got all the prereqs anyway. Even considering the MBA or unrelated masters route, but I know I need more years under my belt to make either worth my time. I don’t particularly hate my job, but doing this forever doesn’t seem feasible either with Oil&Gas always being so controversial in this day and age it feels like the stability isn’t there either. I didn’t become an engineer to push papers and document correspondence all day everyday, hope to solve problems one day.

P.S - things are just looking like they are going to change, the election definitely added to my already increasing anxiety about the economy and my career. Becoming an adult and making big decisions is proving to be annoying.

Stress Tensor for a Spherical Element

so for practice, my professor has given us a challenge of deriving the equations of motion and continuity for a fluid in spherical coordinates. hes done it for cartesian coordinates, and for the continuity equation i got it too, but how do i find out the stress tensor for a spherical element, or even a cylindrical element to proceed with a derivation?

Metallurgical engineering research area idea?

I will be graduating with a degree in Chemical Engineering end of this year, but I've developed a keen interest in Metallurgical Engineering, particularly in extractive metallurgy and metal recovery. I'm considering pursuing my MSc Metallurgical engineering next year and I'm trying to come up with some possible research topic+s I could explore. Since my background is in CE I haven't really been keeping up much with recent advancents in metallurgy- and would appreciate any guidance or suggestion. Whether pyrometallurgy, hydro metallurgy or biometallurgy.

Any suggestions or guidance would be greatly appreciated!

Update: Need Advice on Managing Internship Offers as a Freshmen

Hi everyone,

I’m a freshman from North Carolina and posted here recently and now received multiple offers for summer internships and co-ops. I’m not sure between them and could use some advice:

  • Smurfit WestRock: Engineering Summer Internship and Co-Op at $27/hr + housing stipend + relocation. I’ve heard it's a great experience from past interns in Richmond, but I’m not familiar with the industry beyond cardboard production. I'd work on the process engineering team. I do have some prior experience in a manufacturing environment.
  • The Hershey Company: Year Long Co-op at $23/hr, year-long, no housing stipend + relocation. The projects are interesting (continuous improvement on chocolate products), and taking a gap year is okay since I’m ahead in my coursework. But I'm unsure about the cost of living in Hershey, PA.
  • Chobani: Process development summer internship at $25/hr + housing + relocation. It’s focused on the initial stages of yogurt production. It's in Twin Falls, Idaho.
  • Novo Nordisk: Automation Summer Internship at $23/hr, 40 minutes from home. I'd work on automation projects, though my experience in this area is limited. I do have some biotech training from high school since it was a vocational school.

Would I be better off doing a summer internship in a different industry before committing to a fall co-op, or would it make more sense to stick with one company for both summer and fall/year-round? Any advice on these offers would be greatly appreciated.

Submitting research paper to a journal

Hi everyone,

Recently, I (2nd year undergrad student) did a independent research project on batch crystalization of a certain compound and got it's research paper reviewd by a professor, he thinks it's good enough to submit it to a journal. He told me names of 2 journals to whom I should submit it.

Can anyone suggest name of journals to whom I should consider submitting my paper to, where there is a good chance that it gets published.

properties of compounds

is there any free website that will model the data based on the structure of the particle in order to calculate the heat exchanger?

These are perfluorinated particles and it is difficult to obtain any data. Or maybe someone can give instructions for an idiot on how to do it in DWSIM? Unfortunately, I don't have access to Aspen

Suggestions for going Abroad for Master's to Industry path (Energy, Oil & Gas, Process Eng)

Hello!

I am a fresh ChemE graduate with a 3.75 GPA from a top uni in SEA (ranked 86th in Asia) with 2 months internship exp from an American EPC. Currently working freelance remotely.

What countries in Asia would you suggest to be good for immigrating for Master's and working in the country's industry after?

Currently, I am considering Korea, Taiwan or Austrailia.

I have experience in renewable energy research (publication) and oil and gas internship (EPC). Are my credentials good enough? Or is it worth it to study Master's?

Worth Delaying Graduation for Co-Op Despite Having Internship Already?

Current sophomore/junior, already had an internship at a large company (think Pepsi, L'oreal, P&G type) and am returning there next summer. Is it worth doing a fall co-op w/ a large specialties chemicals company like Dow/Basf/Eastman and delay graduation by a semester? Have the offer already. My goal is to diversify my experiences and strengthen my application for my future.

Is it worth delaying graduation and falling back a cohort for the fall co op opportunity? Or since already have internship with big company, is it not worth it, and I should stick to the regular schedule?

My biggest worry is only having internships with one company at graduation, I'm worried this might limit my opportunities because I only interned with 1 company. 2 different companies I feel would be more diverse and strengthen the application. But falling back a cohort and delaying graduation by a semester is its own opportunity cost and comes with drawbacks.

Thoughts?

Anyone who knows someone/has personal experience with VOC-related damage/cancer risk, how much damage have I done to myself?

I (21M at the time, now 24) worked in a countertop factory for about 5 months. I was instructed to use lacquer thinner to clean off the countertops for inspection. Of course being young and naive, and the older guys shrugging off safety, I wore gloves and safety glasses, but no respirator for the first 2 months until it came to mind as it wasn't offered to me.

I didn't use too much, maybe two water bottle's worth a day. I would finish about 30-40 pieces a day, wiping with the thinner for about 30 seconds to 1 min each. I was in a large ventilated area next to a cargo door that opened 20+ times a day. I smelled it while using it but never felt dizzy or nauseous. Basically it totaled to roughly an hour of light to moderate exposure every day for 2 months. How does this bode for my cognitive/organ health or cancer risk?

Can someone with a chemistry and or medicinal chemistry degree pursue a masters in ChemE?

I was wondering this because of some little pages I found on the internet asking this question, and the answers were mixed. Some were saying a Chem Engineer can work as a chemist but a chemist cannot work as a Chem E, while others were saying that it's easier to pursue chem during undergrad and then apply for ChemE for their masters. So, I wanted to know y'all's opinion.

Job Interviews

How do you guys feel about job interviews that drill you with STAR questions? I absolutely hate them. I had a phone screen with a recruiter for a small pharma company. She started drilling me with STAR questions. I came up with a lousy answer, and she told me that my answer was unacceptable and if I want to do well in the interview with the hiring manager, I will need to prepare for STAR questions. The recruiter reached back out to me for a 30 minute virtual interview with the hiring manager and I’m hesitant to proceed. From what I read on Glassdoor, this company has a tendency to be one way with the webcam with interviewers having their webcam off. I’m so sick of these interviews where they focus more on these stupid STAR questions than actually talking about the role.

Uses of carbon nanotubes in the chemical engineering field.

I’m doing a bachelor degree in Chem Eng and was wondering if chemical engineers could work with CNT. Whether it’s for its synthesis or just working as a materials engineer. Do carbon nanotubes have an important place in the domain of chemical engineering?

Feeling dumb and I need help

Sorry if the tag is not the good one, I will change it if it needs to.

There's my story, I'm currently in an internship at an acid plant. I need to estimate the flow passing in a valve, but there is practically no information about how to do it.

Two weeks ago, I've found some data about the valve, I know the Cv for water. With that, I tried to adapt the Cv for acid, by using Hagen-Poiseuille. But with all of the elbow and other valves, my supervisor told me he is pretty sure it's not laminar.

My supervisor gave me this formula :

q=N1×Cv×(deltaP/Gf)^½

q : flow rate N1 : constant for unit Cv : flow coefficient DeltaP : pressure drop Gf : specific gravity

Yesterday he explained to me what to do with it, but I'm not even sure how to do it. I don't have data for pressure, but I know I consider them like incompressible fluid. I'm working with sulfuric acid so the Gf is 1.8. I'm guessing I will use the same Cv of water for both of the, but another thing is don't have the real flow rate for water, only the Cv with m3/h. But if I use this for the flow rate, that would mean I would find deltaP is equal to 1... and even that, I don't no the unit that they use...

I know I'm not really clear, I'm not looking for someone to do it all for me, I just want to understand a way to do it.
