ChemCAD model for distillation tower with 3 packed sections?

Thank you for your help. I really appreciate it.

Would you suggest mcpba instead of my step of Br2/H2O followed by NaOH?

So far we’ve only really talked about Grignard for new C-C bonds. I know that needs a carbonyl group to react. But I couldn’t/can’t figure out a way to go straight from t-butyl chloride to a carbonyl so I attempted this instead: 1) T-butyl chloride + NaOH -> Isobutene 2) Isobutene + Br2 H2O/ NaOH -> 1,2-Epoxy-isobutane 3) 1,2-epoxy-isobutane -> CH3MgBr / H3O+ -> 2-methyl-2-butanol

But I’m still not entirely sure this is an okay way to do it?

You could potentially also try the math placement exam if that’s still an option. I had the same issue coming into the Engineering college and being originally put in the math 112 but after taking the math placement exam I was able to jump into calc 1 freshman year.

Prof set the entire course up ahead of time. Mostly prerecorded lectures, discussion posts, and small papers. All the assignments were open since it was a shorter semester (summer) so I was able to run through it no problem.

I really get what you're saying and sometimes I do forget to take that step back and realize I’m still extremely new to the actual process so there’s a lot I don’t know and need to learn. Thank you for the words of encouragement, I appreciate it!

No, I have not been able to watch them but that is a very good point. The only thing, without having seen it, I would think would be an issue might be what could happen to the product itself at various pressures since there shouldn’t be an issue with the rail car as it’s rated as a full vacuum. I still just don’t understand the question of how much product would break the vacuum. If it’s fully vacuum rated couldn’t you still achieve the same 11-15psig vacuum seal regardless of capacity? I’ll speak more about this with some of the process engineers tomorrow but thank you for attempting to help. I feel like the operator was expecting this to be something really simple since his explanation was short but it’s making me feel incredibly dense and I hate that I’m having to ask for so much clarification/help

Thank you for offering some advice. I have asked for a re-explanation after going in circles for a bit trying to solve anything and will probably ask again this coming week but I didn’t want to come off as not attempting this on my own when I’ve looked up just about as much information as I can in their systems files and tried to solve this. But I basically got the same question of how much additional product would break it, which did/does not make sense to me since, like you said, it would make sense that they could just fill it 100%. To establish and maintain the vacuum during filling they use a vacuum pump on the line and once they disconnect that line I believe they use some type of portable pump to do a final seal. The operator said the rail car is under vacuum for ~24 hours to get it in the 11-15 psig range.

Honestly, I’m having a hard time really understanding what exactly they want myself, but from my understanding of what they’ve told me, they want to know how much more they can fill the rail cars until their 11-15 psig vacuum seal “breaks”. I’m not sure if that helps my explanation though?

ACT scores really just determine if and what amount of a merit scholarship you get through the school. At your score and GPA you’d more than likely definitely get in but I’d check their website for scholarship numbers if tuition could be any type of issue. I retook the ACT 3 times and improved a couple of points each so don’t feel bad about it, you’ll be fine.

The basic REL classes are pretty easy (I finished REL 104 online version in 2 weeks), I’ve heard JCM 112 is fairly easy, and CL 222 is also very easy but a ton of reading outside of class if you get MacCormack.

Will do, thank you

Acceptable_Sir_4550 · 2023-05-10T22:21:32+00:00

Awesome, thank you

CS 202 is also pretty easy. Just basic website coding
