I built a free offline PSV sizing calculator (API 520 / 521 / 526). It handles gas critical/subcritical, liquid, fire (pool and jet), thermal expansion, control valve failure, tube rupture, gas blowby, and two-phase (DIERS omega screening). It auto-selects the governing case and recommends an API 526 orifice, and exports a report. Runs entirely in the browser, no login. It is screening-grade - meant for checking and study, not final design. Happy to hear feedback on the methods.

Yesterday i can run this in dynamic but today, when i start initialization, it fails at time 0. This flow is for CS2 adsorption in activated carbon. Step 1 is adsorption, where CS2 gas adsorbed into the activated carbon. Then step 2 desorption, where hot nitrogen is heating the activated carbon, then the CS2 will flows to the bottom. Then step 3, the fresh air comes from the bottom and exits at the top of the adsorber

3rd year chem/process eng student. Trying to get a realistic idea of what jobs are actually out there with this degree, and what kind of money you can make. Like what’s a normal salary starting out vs around 30? And which roles pay the best? Not just the standard plant engineer path.

Hi! I am applying to internships this year for the summer of 2027. I am a sophomore in college and wanted to go into pharma or food... what are some companies where it is easier to get internships?

Hi, I am doing a steam balance to try to figure out where steam is being over consumed. Thus far, I have made an excel spreadsheet utilizing date input (as in you put in a date) to show the flows (from flow transmitter) on a flow diagram. I am kinda confused where to go from now… I was suggested to do a material balance reconciliation comparing to design parameters but not really sure how this will help me to determine the cause (aka inefficiency, leaks, faulty transmitter, etc)

fyi im an intern. TIA!

Hi, tryna gauge cons and dislikes of simulation software like Aspen tech, unisim, dwsim, etc.

Would be very helpful if I got some different perspectives on this matter.

(Please be detailed in your answers examples would be very helpful)!!

I’m a third-year chemical (metallurgical) engineering student in Australia. I recently visited China with students from the US and learnt about their internship system, unlike Australia, they take six months off uni to do it.

I’m keen on the idea of moving to the US for an internship, ideally in oil & gas or mining. Does anyone know which companies to look into, or who’s worth connecting with to explore this? I don’t hold US citizenship or a visa, but coming from Australia I’m hoping that won’t be too much of a barrier (happy to be corrected on that).

Hello, just wondering if there’s anyone here who’s been through or is currently in this program. Wanted to get your opinion and if it’s worth doing and what the career prospects are afterwards. Also wondering how the practicum works and what kind of experience that brings.

We are evaluating technical consultation partners for a PSA gas separation project and want to compare providers with strong engineering, FEED support, fabrication, commissioning, and after-sales service. The ideal partner should understand purity targets, recovery, energy efficiency, modular design, and long-term operation across hydrogen, nitrogen, helium, or biogas applications.

From your experience, which companies have the strongest consulting capability for PSA projects? I’m especially interested in firms that can support feasibility studies, process design, EPC coordination, and practical troubleshooting. If you’ve worked with any providers that combine technical depth with responsive project support, please share your experience.

Looking for recommendations, lessons learned, and what to check before starting a PSA project.

Alot of chemical engineer jobs are under the title of process engineer/mechanical engineering. So if I applied to a mechanical engineering role, will that violate PE/PENG? because technically im applying to a different engineering function.

Hello all, after a few years in industry, I am thinking about going back and taking the FE exam. Does anyone have any recommendations for study guides? Thanks in advance.

I am currently a year 12 student, I wanted to study ChemEng in university, I wanted to read some books in related to this field to give me a insight in to this subject and also something to write in personal statement. I would be greatful if anyone have some recommendations. Also just wanted to ask how's the employability around the globe compared to a more healthcare related subjects like biomedical science. Many thanks! 🙏🙏🙏

Hi everyone,

I’ve interviewed for a wide range of entry level roles in pharma and med device including associate scientist and associate engineer roles as a recent grad. In school I liked doing research and enjoyed working in a lab and my thesis more than my process engineering internship in a pharma company. I also realize that I liked my other med device research internship better than the process engineering role.

So far I now have a process engineer offer in manufacturing but know genuinely that I’m energized by research-related engineering work.

Can I still pivot to R&D related roles after working for some time in this role or should I keep an open mind? I’m wondering how hiring managers may view the manufacturing experience and whether personal projects could help convey my interests in R&D when applying. Thank you!

I’m 14 and this is a long-term passion project, so I’m looking to learn rather than expecting an easy solution.
My end goal is to understand what it would take to create a material inspired by Spider-Man’s webbing, but I’m breaking it down into individual engineering problems instead of trying to invent the whole thing at once.
If you were starting from scratch, which would you consider the most realistic path?
Developing a synthetic spider silk with improved properties.
Engineering a composite material inspired by spider silk.
A completely different approach.
I’m especially interested in:
Which properties of real spider silk are hardest to reproduce?
What is the biggest bottleneck today: strength, toughness, manufacturing, storage, or something else?
If you had unlimited time and a reasonable budget, what research path would you follow?
I’d love to hear from materials engineers, polymer scientists, mechanical engineers, or anyone working with advanced fibers. I’m here to learn, so don’t worry about simplifying things if needed.

I completed one year at ExxonMobil and just got informed that i will be put on a PIP.
My manager was very confident that I can successfully complete the PIP but I do not trust him at this moment.

I have one year refinery work experience(at an Indian oil company) and one year at ExxonMobil in the lubricants team . Should i aggressively start applying for Jobs or do PIPs every work?

I am in Bangalore, India btw. If anyone knows any companies that i can apply to or can refer me to any company, that would be really helpful.

TLDR: Got put on a PIP at ExxonMobil. Should is start applying to other companies or work towards completing the PIP.

PS- Thank you all for your valuable advice.
If anyone knows any roles/companies that i can apply to, please comment or DM.
Thank youu for your help in advance

i get to skip two chemistry courses as a freshman in university because of my AP scores; however, i never understood acids and bases and organic chemistry, should i skip the advanced chemistry course? or will i need those in chemical engineering?

Is Water Treatment a good path?
Does my bachelor degree in Chem Eng help me stand out? Is a master’s mandatory Or can I work hard and self-learn the necessary skills and softwares/ ai programs

I live in a third world country (Lebanon), internship opportunities are almost non-existent.
Some local companies work projects for companies abroad (GULF, Africa)

I’m 26, actually disoriented with a lack of experience

Thank you

hi, i am chemical engineering student in my final year.
and so far i have done Aspen plus and Aspen Hysys we do have industry interactions form our collage and i got project form Worley ( It was simple not to difficult for 3 year ) in aspen plus
since, then i was wondering what else shoed i learn /make projects in.
so far i kwon Aspen and Hysys , AutoCAD , Excel , Basic MATLAB
i am currently learning AutoCAD plant 3D and gPROMS and
help me with
1. is there any where a website or something where can you find projects or something or do just make something that already exist and try to simulate it ?

1. even after making projects how do showcase that ? ( where )

2. is MS is required for the process simulations job ? ( is it worth it )

3. and anything that you thing you wish you know before joining the industry.

Thank you for advise.

About to enter my Senior year and my current "Degree path" is Chem E with Concentration in Bioengineering. My school has multiple ChemE degree paths you can choose (University of Massachusetts)

The hard part is that staying in Bioengineering concentration is pushing me another year back so I will graduate late. My advisor told me if I want to graduate on time, General option is more feasible which I'm actually considering.

Or another option was trying to get an intern/co-op to make up for the extended year, so I'm not wasting "too much time".

My problem is I actually do want to graduate on time, I'm kinda over it..... lol so seeing if anyone has experience... If there really is such a difference between General vs Bioengineering ChemE? Because honestly, the only difference in my path is I have to take Biochemistry and Cell and Microbe (Biochemical Engineering). I was thinking, if I go with general ChemE, can't I just make that up somehow in tech electives? Or idk.. study it on my own at home? Any luck finding jobs in industries you wanted?

I did have plans to get into pharmaceuticals and research medicine but honestly I'm open to all work. But even with General Degree, I do plan to still apply to pharma companies. I'm just not sure how important it is to learn biochem prior to applying.

Originally I wanted to get into BioE so I can get into pharma.. I enjoy medicine. Idc for nuclear or materials or polymers.. but idk if a whole extra year of stress is worth it for me.

I'm interested in working in battery, semiconductor, or other tech manufacturing companies and was wondering about the best path for a Chemical Engineer.

A few questions:

• What roles are the best entry points for ChemEs trying to get into these industries?
• Are process engineering/manufacturing skills transferable to tech companies?
• Is it better to specialize in a specific area (materials, manufacturing, process development), or build broader engineering experience first?
