My name is Karen Braden and I work for a chemical company called Clariant and I'm currently working in the Syngas industry (ammonia, hydrogen, methanol!). The goal of this TH-cam channel is to share educational information about our catalysts and adsorbents that isn't easily google-able. Let's all learn together!
AICHE Paper - Temperatures Greater Than 100°C on HTS and LTS Catalyst
Full disclosure - I did not write this paper and I am not familiar with this site. I am just sharing a little bit of information that I found interesting during the #AICHE #Ammonia Safety Symposium last week. 💡
One of the papers that was presented talked about an HTS / LTS catalyst overheating scenario where the catalyst experienced temperatures up to 1010°F / 1850°F. 🌶 After shutting down, this site was able to run on its #Clariant catalyst for another seven months at full capacity before a planned outage and catalyst replacement.
The paper discusses how this occurred and the subsequent steps after to allow the plant to run for another seven months. 📑

What to do if you see heavies coming in to your Syngas plant with Taylor Archer

Let's discuss what happens when you get heavies coming into your #Syngas plant with Taylor Archer! What are some things to look at if this happens to you? 1) Monitor the dP in your zinc oxide (ZnO) bed as well as sulfur in / out. a. Heavies can crack in the feed gas coil resulting in carbon laydown on your ZnO bed which could be seen by an increased dP b. With heavies sometimes come sulfur whic...

Tube Wall Temperature Monitoring - Primary Reformers / Steam Methane Reformers with Anton Kariagin

Today I am speaking about tube wall temperature monitoring (TWT) in steam methane reformers, this time with Anton Kariagin. 👍 Anton helped me think about TWT monitoring being used for two separate goals 💡: Goal 1) Checking that your TWT does not exceed the design temperature of your tubes. (Running over design significantly decreases your tube life.) 📉 Goal 2) Primary reformer / steam methane r...

Big thank you to Patrick Hayes for talking through this one with me! 👊 (I enlist one of my colleagues on each of these videos to talk through the topic for accuracy and make sure there aren't any major points I'm missing that need to be added and Pat is just one of those colleagues that helps me frequently.)

What not to say to pregnant women

Unrelated to catalyst but related to pregnant people (which none of us would be here without so relevant to all in my opinion 😀 ).

One of these items is not to comment on weight or size. Some people might be worried they're gaining too much wait, ...
Ammonia synthesis / ammonia converter contaminants
มุมมอง 745 หลายเดือนก่อน
Let's talk about contaminants in ammonia syn converters - typically water, CO, and CO2 coming from the upstream methanator. These show up in your loop as reduced activity. 🌊 We recommend keeping the total CO CO2 content less than 10 ppm, ideally less than 5 ppm. If you operate at higher levels (depending on duration and severity), you may say chemical sintering resulting in permanent activity l...
Secondary Reformer / ATM Spare dome AND Average SMR / Primary Reformer Tube Life
มุมมอง 266 หลายเดือนก่อน
Today I want to share a few things I learned at our Catalyst and Operating Training Seminar for Syngas Plants (a month-ish ago). 💡 1) Some companies with multiple sites actually keep one spare secondary reformer or ATR dome in inventory (for the fleet) in the event that they unexpectedly need to replace their dome during a turnaround. Lead times for these items can be long and you can't really ...

I have analyzed your TH-cam channel. I found some problem with your youtube channel. If you want, you can solve the problem and grow your TH-cam channel. Day by day your channel will grow and you can monetize your TH-cam channel. What are your plans for TH-cam channel? can you tell me I am always ready to help you.
Hello, great videos. Thank you. What are typical hydrogen and nitrogen efficiencies in a modern plant?
What I've been seeing lately is: H2 efficiencies: 87-103% N2 efficiencies: 87 - 99% Of course you can't exceed more than 100% efficiency but all of these numbers are also based on the quality of data that is received and measured.
@@karenbraden5833 Thank you!
Very Nice presentation, Karen. Zero Bad Information.
Glad it was helpful!
Best explanation that i have ever seen Thanku ❣️
Thank you!
Does midrex process need to be feeded only with iron ore pellet?what about low grade iron ore?
That's impressive! Were you able to maintain optimal performance with the less active catalyst at the same inlet feed gas temperature, or did you need to make adjustments?
I was looking for my sister, you aren't her. Congratulations on your family.
Hi. So it is an ammonia plant. Neat!
Hello. I am interested in a "wood alcohol" bio-reactor. Google is really bad now so it is hard to find information. If you do read this I would like to know how to do a more low-tec non-catalytic bioreactor. I would like to use wood scrap to produce methanol but I am finding more information about the CO2 catalization. Thank you for sharing.
Hi Karen, Thanks for the quick video of advice! I recently got employed as a process engineer and have been thinking of taking the PE once I reach the experience point. Is it common for companies to pay for the exam fee as well? Do you think it's a poor idea to take the test perhaps in a couple of months while university material is more fresh in my head?
I don't think you're allowed to take it until you have around 5 years of job experience. When you apply to take it you have to list your job experience and then get approved before you can take the test. My company paid for the course and for the testing fees if I remember correctly.
@@karenbraden5833 I've heard mixed things, as I was absent the day my undergrad kinetics class had someone come in and talk about it. I'll definitely apply to take it after 5 years of working. If it's a similar process like the FE, it should be good :)
Can you make a video on the pros and cons on the different types of methanol reactors. I'm currently doing my design project on a methanol reactor and unsure whether to use a quench or water-cooled reactor.
Some of these might be helpful: th-cam.com/play/PL2uiTIn3xa-t6D71IK_nOvwcmujRaCbJ6.html&si=l735VCp8AHVRFUce
Assuming by process gas you mean a composition of CO2, CO and H2, could this converter type used for methanol synthesis from syngas obtained from waste gasification?
How can I contact you? We are going to change our reformer catalyst
Please send a note via the Clariant website or look for Karen B at Clariant on LinkedIn.
Making a drawing instaead of storytelling it, helps to save hand labour whyle talking.
xD agree
owning one of these places urself is a big thing to do, all on your lonesome, even with other people.
Hi Karen , I appreciate the content. Please could you elaborate a little more how did you come to the conclusion that these reactors are rarely used in design these days? Thanks
Hello - The new plants that we are seeing being built are not using this design in their methanol converters. This is just based on my experience in the methanol industry (and speaking to others in the methanol industry) - if you know of know plants being built that are using this design I would love to hear about it!
Beautiful
Thanks for great videos about methanol production. I understand it might be a lot of work but I would love if you had the time to explain how a methanol production plant would work using direct air capture of the CO2. I think this is the future since then you could make liquid fuel with zero emissions in the most efficient way. Also, it would be the most convenient and efficient way to store excess renewable energy. 🌍🐆🦏
Thanks! Just note that the video is twice looped at 0:49
Thanks for sharing! I agree and I could just expand :) I usually think that there is a certain probability that I get the job, achieve what I want etc. I can never make it a 100%, however, I can work on increasing the probability and no matter if I get the job or achieve what I want, doing the struggle will always improve me for future problems. It is always way much better to engage in to something then not trying since you learn so much more than the alternative!
Love this!
Thanks!
You are welcome!
thanks
Thank you Karen. Just found your channel. Very useful information. Keep up the good work. A fellow ChemE here 🙂

Hello! From my understanding, chlorides can be organic or inorganic and are a poison that can cause stress corrosion cracking.
Good video
Thank you!

Thanks, post some more. I'm interested in green hydrogen, ammonia, and methanol as future fuels.
Thanks for running through this.
I hope it was useful!
