Aspen Plus Help: CO2 methanation

Trying to create a simulation for a power to gas plant but am encountering issues with the kinetics when plugging in a plug flow reactor. Can go into more detail if asked but basically methane yield is extremely low and have tried different kinetic parameters as well, but nothing has worked out so far. If anyone has modeled the CO2 methanation reaction (3 reactions) in a PFR in Aspen Plus, please help! So far, I have been using GLHHW since the denominator is the same for the three given reaction rate equations. Have already read many papers for what they did but my simulation never works out so I’m wondering if maybe I’m not inputting something correctly. Am hoping if someone has modeled this reaction before in Aspen plus.

Is experience in Analytical Chemistry "relevant experience" in the field?

I was thinking about pursuing a PhD in Germany but my gpa is not that good. So maybe I could finish my masters here and improve my chances to get into a PhD program? I want to believe they'll take my most recent gpa into account (Masters).
And, maybe analytical chemistry work experience can be considered experience in the field of chemical engineering?

programming projects for chem eng resume

Hi everyone, hope you're doing well. I'm wondering what kind of coding projects would help a chem engineer resume stand out. I'm graduating next year and want something to help my resume a bit.

I know full stack web development however this doesn't seem to really relate to chem eng.

What kind of projects do you think an employer would an employer like to see?

How can I conduct an energy balance around an adsorption column for treating water?

I'm writing a paper for my Plant Design course and I'm having trouble with finding relevant references I could use to do the energy balance. I've attached our material balances for these equipment. Right now we don't have any calculated operating conditions. And I'm not having any luck finding previous studies that discuss this topic that I could refer to. I'm not sure what information and relevant equations I need to be able to calculate for the energy balances.

Which university should I go to for Chemical Engineering

Hello everyone I have been accepted recently to UC Davis, UCSD, Colorado School of mines, and Texas A&M. I don’t really know where to go so I need help from experts in the field. I mainly want to work in either the renewable energy sector or just go full on Petroleum and Gas which may sound contradictory I know that. However, for the sake of the question consider the petroleum sector and everything related to it.

Which university from these is most preferred by big companies like Shell, Exxon, or even Aramco since i am Middle Eastern. Since all these universities are ABET accredited I only hope you give answers according to international recognition by petroleum companies worldwide.

Btw I really want to work in Shell so if any Shell employees answer this I really appreciate it.

Sorry for my English, I promise I am going to improve as I arrive to the US in September. In advance, thanks to everyone for answering.

In my Homecountry, ChemE's are Earning as much as Surgeons

Hello,

I was doing research for job opportunities in foreign countries and found out in many countries like Usa, Canada, Australia etc. Chemical Engineers are not earning much compared to other professions. For example, the USA's GDP per capita is 75.000 dollars and an average ChemE is earning only 2x of it which is around 150.000 usd gross.

In my country, a chemical engineer having 10 years of experience and working in a good position might earn around 5x the gdp per capita. Also, the total compensation is around the salaries of average surgeons and specialist doctors which is great because doctor have lots of more working hours, stress and responsibilities. A senior ChemE in a managerial or senior individual contributor might earn around 3000 dollars per month take home whereas a surgeon is earning 3500.

It is strange the market is like that in countries like USA, a ChemE graduated from top universities is not earning at mid career at least as a specialist doctor. You become the most successfull student in your class, go to college and learn mind blowing topics (fluid, thermo, heat, controls etc.), design or operate chemical plants and then earn only 2x of the gdp. How is that possible? Do all the hard work and earn 1/3 of a doctor...

Remote Work Possibility in Process Design & Epc

Hello,

I am living in an Eastern European country where the minimum salary is about 500 usd, junior epc engineers earn around 1250 usd, senior epc engineers earn around 3000 usd, speacialist doctors and surgeons earn around 3500 usd. All are take-home salares.

Even though the pay for chemical engineers is not so bad compared to other professions, my aim is to work as a remote senior/principal process engineer after 5-10 years for a company in a rich country like USA, Canada or Gulf countries.

What do you think about it? Would it be possible to find a completely remote job if we have a good cv in multinational epc & process design companies? I have currently 4.5 years of experience and working in an worldwide epc company office in my country.

If I could have a remote job with a pay of 4000-6000 dollars per month in the future, it would mean a really good lifestyle for me and my family since it nearly means double of a salary of a surgeon in my country. And also as you know, the process design work life balance is good and stress is low.

Also, what do you recommend for doing that. Currently i am trying to learn simulation softwares. Is my target attainable? Maybe not full remote, but kind of a hybrid schedule like going to work 2 weeks in a month maybe and i can still live in my homecountry. Or just for site visits.

Thanks.

Aspen Plus - a cry for help to anyone with access

Hello, to keep a long story short I really need access to an example model that’s listed under the resource tab. When I try open it, it opens a blank worksheet. I suspect that because my university hasn’t updated the software in a few years.

If anyone can download an example model for me and send it to me I’d be extremely grateful.

The model is called “Example: Modeling a Circulating Flash Evaporator”.

Thanks to anyone that can help.

One Year Masters

I’m in my 3rd year in Chemical Engineering at a highly ranked state school with a good GPA. My school offers a masters program in chemical engineering that is 30 credit hours. The cost is reasonable and would not be an issue. I am interested in going in to pharmaceuticals, potentially drug discovery or vaccine work, and want to know if this would help my job prospects. Good research experience, no internships or co-ops. Willing to live anywhere. Should I do the masters?

Making Enzyme for Dog Urine

It costs over $100 (on special) for 5 litres of dog urine enzyme cleaner where I live.

Can I make my own?

Or can I use something like biozet washing powder which claims to have the three main enzyme types in it?

How do I do this flash calculation?

I have a chemical reaction in a batch reactor where the outlet is comprised of 2-amino-2-methyl-propanol (2-AMI), water and my product.

The reaction takes place at 105 deg. Celsius. I have to separate the product from the other 2 components. So I was thinking that since the reaction has high enough temperature I can conduct this reaction at maybe a slightly higher temperature and vapor out the water and 2-AMI directly from the reactor and then condense them later. To calculate how much vapor is released, the temperature required and the vapor composition, how do I do that?

Also I am trying to learn Aspen so if anyone knows how to simulate this, that would be great !

Sales engineering to design the R&D engineering?

I’ve been working as a sales engineer for about 2 years. The job is great, but I suppose I want to go into a more technical role. I do have a degree in chemical engineering, but the degree did not offer any CAD skills.

Questions: How can I transition into a design or R&D engineering role? How can I develop the skills like AutoCad and Solidworks? How proficient do I need to be for an entry level role? Can I tailor my experience as a sales engineer to a more technical role?

Companies with the best work culture in each industry?

I know this depends a lot on managers, but anyone have a list of top ChemE related employers that treat their employees well. I know that in Pharma it’s AbbVie and Eli Lilly and in chemicals it’s Dow and BASF. But what about other industries?

NAPTA (PTech) Exam

I’m starting a new job at a chemical plant and one of their requirements is to take the NAPTA Exam. Does anyone have experience with taking the North American Process Technology Alliances(NAPTA) Exam? If so, can you give me some books or websites that maybe helpful when it comes to passing the test.

Pharmacist to ChemE?

I have a chemical engineering degree that I never used. I graduated in 2009 and had trouble finding a job so I got a PharmD and have been working in the pharmacy field since 2011 (tech-intern-pharmacist). Now I'm wondering what options are out there or if I should even consider a career change. I currently work in retail and I'm in a really good situation as a pharmacy manager right now. I've got a pretty good work/life balance but I foresee it going the way most retail goes with hour cuts, pushing metrics, and unsafe work environments. I've been really lucky that Walmart is big on safety.

Would it even be feasible to try to make a switch? I never even had a job in engineering other than a co-op in the paint department of a car manufacturing plant. It'll probably be at least a $50k pay cut. I'm aware that engineering is completely different from what I've been doing.

Anyway, it's just been something I've been thinking about and wanted to see if anyone had input or advice. I don't dislike my job right now and this might just be me feeling stuck where I am.

Maximizing the Internship

Hi! I'm a fresh graduate who recently got accepted for an amazing internship in the R&D department (testing and working in labs) which is my chosen field. Although it's unpaid, I know I can get a lot of experience from this.

This is a rare opportunity given my background and the country I am in (with jobs unfriendly to new grads) so I just want to seek advice:

How does one maximize his internship to be able to land good jobs or maybe even get absorbed in the company he's interning in?

Doubt on rocess control engineering

What specific skill set one should get to become engineer in control industry?

I think ontrols engineer works on creating flowchart for automations, creating recipe modes etc. But do they only create logic or work on integrating the same in to DCS?

For example in my organization, we deal with mostly batch plants. For optimization, I sometimes create logics (flowchart) for control loops and give them to our instruments engineer... Who then integrates it to DCS. so here instruments engineer is doing process control engineer's job?

Internship Ideas

Hi, I have applied to all available positions in my country for an internship. Now, I have started to manually send applications to companies that do not advertise their internships on platforms like LinkedIn. Do you guys have any ideas for processes that I should search for to find these companies?

So far, I have applied to companies involved in processes for cement, paper, bauxite, copper, gold, soda ash, glass, food, fertilizer, paint, detergents, textiles, oil and gas.

As a student, I am not very knowledgeable about the range of what chemical engineers can do. Any help is much appreciated.

American Chemical Engineer with a Canadian Fiance. Looking for advice.

My fiance and I met while I was in graduate school. She got a great job in London, Ontario. I took a job in the USA. Our goal has always been to reunite and move to Canada after we get married, and I get residency. We are getting married in December. She isn't a chemical engineer, but she has friends who are engineers in Southwestern Ontario. We are trying to use friends and family connections to find me a chemical engineering job closeish to her job in London, Ontario.

I am looking for places in Southwest Ontario to apply. My current job is primarily environmental remediation (water, soil, air) and demolition (rehabilitating old industrial sites). I also have experience in government contracting, teaching, and disaster preparedness and response. I have been finding connections through my current job as well.

My current list of potential companies in Canada to apply for is: Jacobs, Wsp, Newterra, AECOM, Tetra Tech.

Do you have any other suggestions?

Anyone here pivoted into MBB?

Hi all,

I am in my early stages of my career (1 year in Pharma before my masters) and I joined a big Engineering consulting firm recently after graduating from my masters course and was immediately seconded full time with a big energy client. Today I made a lateral move to a Management consulting role within the Business Consulting arm of my firm via networking.

My goal is to break into MBB (McKinsey, Bain, BCG) within the next year or so. Just wondering if anyone has any advice on how to make this transition? Should I apply directly to an entry level role when they open for the upcoming cycle? Should I gain some more experience in consulting within my current firm and pivot into an Associate role?

Background:

  1. BE ChemE ( Mid level UK university)
  2. MS ChemE ( Target UK university- Think Oxford/Cambridge/Imperial )

Things I am already doing:

  1. Self teaching myself Corporate Finance, Accounting, Valuation and Modelling.
  2. Practicing casing and learning all the frameworks for casing interviews

Midstream Oil and Gas or P&G offers

I wanted an opinion as I am stuck between two options after graduating college

  1. Midstream O&G offer in downtown Houston with a 3 year rotational program and after the 3rd year I would most likely return to Houston full time. Location is ideal as majority of family and friends are from the Texas area. Company isn’t a super major(Shell,Exxon,bp,etc.) but Is top 10 largest midstream companies. Also has remote work on Wednesday and Friday which is huge plus. Annual raises are standard (3-6%)

  2. P&G offer is in West Virginia. No plan on how to get back to Texas with P&G in the next 5-10 years. Goal would be to get to HQ in Ohio after 5 years. HQ should have hybrid work model. P&G has a good growth and a good long term career. Also after talking to several employees, I learned that high performers get around 10-15% raises annually. In addition, P&G would be great for getting into a M7 MBA school because of the name and the work I’m doing is more leadership oriented. Could potentially get MBA after working for 2-3 years and pivot into consulting later in life. I don’t know if it’s worth giving up seeing my family for the foreseeable future to go to the big name or for a potential top tier MBA.

TC at both companies is about the same starting off.

Questions :

  1. Is it easy to job hop between different midstream companies in Houston for pay raises?

  2. Do I still have a high chance of getting a M7 MBA from working in O&G?

  3. Midstream is pretty stable for O&G but P&G is even more stable because it’s consumer products? Should I be worried about losing my job at all with Midstream(assuming I’m a good engineer).

What offer do y’all think I should take?

Can you help me about this

How should I explain that why the filter medium resistance drop. But my specific cake resistance is higher as the pressure increase. Noted that the slurry concentration at 20 psi is not the same as in 10 and 15 psi (it has diluted).

Thank you very much ;___;

First Career Advice

I am graduating this May and wanted to ask for advice regarding an unofficial job offer. this morning I got an unofficial offer to work for the New York department of health. This role focuses on their drinking water program for the state. The role involves hands-on technical support to public water systems, conducting inspections and site evaluations and performing field investigations. I was hoping to get a more standard chemical engineering role (process/controls/manufacturing engineer) and I am still actively looking. Is this opportunity to work with the department of health a good opportunity and a good choice as a first career into chemical engineering? Anyone work for a similar position and have any thoughts on the role? I am just not too sure if this role will hinder my future growth/transition to another industry. I'm also not sure if this role has a lot of chemE, I really enjoyed what I learned in my courses and from my understanding it seems like this role is more technical writing and inspections. But also I have no industry experience, so I might be wrong. Any help would be appreciated thanks!

What type of compressors are used in the natural gas hydrocarbon industry?

I've been looking into toluene disproportionation and have thought about how large the compressors need to be to feed the reactors which usually operate at 400-500 celcius and around 30-50 bar. Has anyone had any experience in the compressor field?

Who’s hiring around San Antonio?

I got the degree and passed the FEE in 2010, but I’ve been in the Army for 13 years so I’m basically looking for entry positions and I’m definitely not in a traditional recruiting pool… do I need to swallow my pride and look for a paid internship or go through a recruiting/temp firm, or do I have a shot at actually getting my FRAC on out in Pleasanton?
