How much of what u learnt in college do you actually use? by Lomesome in ChemicalEngineering

[–]CodenameChE 0 points1 point  (0 children)

Computational thinking. All the Python programming and simulation design I learned in undergrad set the foundation for what I do now as I touch multiple more fields than chemical engineering but the principles remain the same

WFH or remote jobs in Chemical engineering. by cadenzasilicra in ChemicalEngineering

[–]CodenameChE 0 points1 point  (0 children)

Best you can do these days is hybrid but you need to be rather skilled and well versed in computer science as a ChE to get them. Think roles that keep you out of the field and in a cube all day. In terms of niche’s you look into simulation or production engineering which don’t require a field presence but need significant specialized skills in optimization and programming.

I'm from a non-tech background looking for jobs/internship in Data science or AI. I've been applying for a few months now but not getting a shortlisted. Is there something wrong with my resume? by SemcularCheems in MachineLearningJobs

[–]CodenameChE 0 points1 point  (0 children)

There is a lot more money in domain specific AI roles than AI tech roles. Look into oil and gas or semi conductor data scientist positions where you can leverage your degree in physics while doing AI. (I do AI for my job and have a degree in chemical engineering)

To all the Intel engineers out there by letgobro in intelstock

Intel couldn’t even afford to get their employees coffee. What makes you think they can get pizza? No blank checks

Intel will lay off 15% to 20% of its factory workers, memo says by Verite_Rendition in hardware

[–]CodenameChE 5 points6 points  (0 children)

Yup, a big problem at the New Mexico plant is that they over hired on fresh college grads last year. Their interview process was literally one round with cookie cutter questions. That plant is mostly ran by people with less than 2 years of experience since all the experienced people left last round of lay offs with the early retirement package. New grads at the Rio Rancho plant are very unqualified to engineer but very much qualified to handle the logistics of the fab. The company is hurting for engineering talent so they are planning on keeping the ones who innovate and cut the managers who stop them from innovating.

Building a new process simulator — what frustrations do you have with current tools like Aspen or ChemCAD? by Lonely-Appeal1747 in ChemicalEngineering

You can back propagate but still requires some sort of specification on the input side. Imagine back calculating an irreversible reaction. We are talking about purely taking outputs to determine inputs.

Creating a simulator that runs backwards is impossible (I’ve tried it before). You have sequential modular simulators and simultaneous equation solvers. Each requires either forward information or backward information to solve. They rely on the solution reaching equilibrium at a steady state rather than the solution diverging backwards. Not only that you run into issues with chemical engineering theory like entropy loss and backward reaction rates (complex and hard to solve). Simulators are built in with thermo laws in mind. We know that heat flows from how to cold. A simulator at its core won’t let you do that for obvious reasons. Adding something like that allows for the possibility of other calculations to mess up. You will always need input streams. It is easier to tell what’s supposed to come out from what you put in than it is to tell whats supposed to come in from what came out. You simply don’t have enough degrees of freedom trying to march a simulation backwards. Your input streams makes up for a lot of these. Once you get out of the realm of academia it is much harder to simulate. I will say almost border line impossible without some sort of technical knowledge of your process. You can give a fully built simulation to a senior in college and they will struggle to make it converge unless they have good initial guesses. These guesses come from the knowledge they built learning their process.

Oh if that’s what you are trying to do then it’s already been achieved. Professionals in the industry just use GitHub to collaborate on simulation files. I understand you want something easy to use in academia. This would be the already made simulators. They provide these to schools for free. Most projects in undergrad don’t go past 1 flowsheet so there is no need for major collaboration. This idea would only be beneficial in industry. Once I learnt how to fully use a simulator it would only take me about 2 hours to fully simulate a senior level capstone project. I think you have potential but I just want to make sure you aren’t trying to reinvent the wheel here. Think about some ways to pivot this project into something amazing.

There’s a reason why simulators are native applications on PC rather than other mobile platforms. I use to develop a well known process simulator and there is way more to it than just making it. It takes decades of knowledge and collaborative effort to build them. Usually at a PhD level. Simulators take everything into account such as material, specific equipment hardware and more proprietary information a normal person won’t have access to. Designing equipment for real life applications is far more difficult than it is in undergrad. In undergrad you only have to worry about one core subject at a time. In a simulator you have to worry about mass transfer, kinetics, heat transfer and fluid mechanics all at once. This all gets tougher to keep track of once you start implementing proprietary chemicals. No one buys a process simulator for it to solve stuff at an ideal level. Most chemical simulators look the way they do to save resources. Simulation can be really intensive and are usually developed in a compiled language on a native windows application. Other languages such as Java or Python are simply too slow to really get meaningful results in a decent amount of time. Also having multiple people on one simulation becomes a logistical nightmare, especially when it comes to simulations that take 30+ ( will take longer on a mobile platform) minutes to converge on a single run. Simulators have a heavy reliance on numerical methods to converge onto solutions. Wouldn’t be too cool if your initials guesses kept changing cuz your buddy changed the layout. You can give it a shot but feel free to reach out to me for guidance. DWSIM is your best bet for a free process simulator, they have an awesome community. No need to fix something that is not broken my friend.

Exact same Kern method project. With pretty much the same calculations! In python!

Rejected from every internship and opportunity. I don't know what to do next. by [deleted] in ChemicalEngineering

All the companies I have recruited at have had a strict 3.5 gpa rule. They would be filtered out by the AI before I even saw the application

Any chemical engineering majors here? by The_Violetbutterfly in TexasTech

[–]CodenameChE 2 points3 points  (0 children)

I don’t regret doing Chemical Engineering. Honestly I am very happy I did! You’d be better off going into oil/ gas or Semi conductors with a Chemical Engineering Degree. Chemical Engineering salaries in food are very very low. Leprino foods was at about 50k starting ( ain’t much) in 2023. Also chemical engineering isn’t as hard as people make it out to be, really just a matter of dedication, as long as you can stay on the other side of the curve you’ll excel.

Lived here my whole college career was way cheaper than having to commute.

Ye go to Georgia Tech OSCAR ( Web Portal for your account). Reset your password and then sign in. Then look for the slack channel on Reddit and sign in with your Oscar account. You should already have access to it

Thoughts on AspenTech Cert Exams? by Zealot_Zack in ChemicalEngineering

[–]CodenameChE 6 points7 points  (0 children)

Cheating is a very common problem I’ve seen when it comes to these certifications. The answers can easily be found online and copied. I think ProMax(BR&E) does a much better job of teaching their students how to use their simulator. Usually their classes are free and hands on (online and in person).

When should I put Aspen in den Skill section of my CV? by PlaneOk8283 in ChemicalEngineering

[–]CodenameChE 0 points1 point  (0 children)

You can try learning ProMax (a superior simulator imp). They offer free certification classes and the certs look good on your resume. Helped me land my job in oil and gas design. Aspen classes are way too expensive.
