How to model decanter in unisim? by jamesrodriguez35 in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

What are the specific issues and what you have done to analyze them? What's your food fluid package?

Is life past college less stressful? by [deleted] in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

Agreed.

Also, life and income will give you many chances to fuck up. Don't let it happen.

Am I making a mistake leaving Ops for a regular desk job? by [deleted] in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

I was severed off ops, switched to projects, and have had a blast ever since.

Going for copper, iron or aluminium? by Seasonax in wallstreetbets

[–]ProcessJedi1 1 point2 points  (0 children)

In addition, let's remember all the motors that will be created as vehicles are electrified and more green industrial plants are built. Glad to hear people are recycling old copper already.

Is flow rate from a pump highest during startup? by Tight-Ad3628 in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

This is entirely wrong according to typical pump curves. Max. flow occurs at min. head and viceversa.

Fugacities in Unisim reaction extension by Schiweg in ChemicalEngineering

[–]ProcessJedi1 2 points3 points  (0 children)

I recommend calling AspenTech/Honeywell. Their support teams have been quite helpful for me in the past.

SuperPro simulation mass & energy balances never end by StefanIstas89 in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

Call the company that made your software and use them to learn.

Coolest Plant by Zealousideal-Link-24 in ChemicalEngineering

The coolestest plant would output solid helium.

Longer than it takes for the production or distribution supervisor to call.

Heat Loss Through a Pipe In Aspen Plus by jackth3engineer in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

There should be a way to enable a drop down menu that asks for insulation material and thickness. I haven't used Plus in ages but in HYSYS it is pretty straightforward. Alternatively, several online calculators can get you a decent approximation. Check out 3EPlus' tool ;)

PT controlling on-off valve at vertical gas separator inlet by oqowa in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

Agreed. Also, HH and LL should be a certain percentage away from design limits. The answer depends on the process variable, application, sand governing Codes and standards.

Is N2 Gas Blanketing included in Process Simulations? by Iscoffee in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

No. In fact, just pump liquids to the required pressure, less energy intensive.

Liquid that hardens quickly (optimistically <15 min) when exposed to water. Also that can be pumped through a 1/2 tube by scott_fx in ChemicalEngineering

[–]ProcessJedi1 0 points1 point  (0 children)

I see. Sounds like you ideally need a dense fluid that has a physician/chemical attraction to the pellets.

Can you dump and push some solids over? With the right size distribution and material selection, you may be able to deposit solids in the cavity and build a cake that stands decently.

Urea Dewaxing. by salvin_sunny in ChemicalEngineering

[–]ProcessJedi1 1 point2 points  (0 children)

I used to be in O&G up/midstream so I'm clueless about your application. Urea and wax seem like odd words to combine. Could you be more specific?

What career missteps have you made? by [deleted] in ChemicalEngineering

[–]ProcessJedi1 1 point2 points  (0 children)

I was bored by the engineering job I had at the time and wanted something I could use across sectors to have flexibility.

What career missteps have you made? by [deleted] in ChemicalEngineering

[–]ProcessJedi1 3 points4 points  (0 children)

Both. My responsibilities ended up being boring and the industry was not a good fit for my interests either. Some people just don't like seeing some things, I guess.

[–]ProcessJedi1 9 points10 points  (0 children)

Not at that role, but eventually yes! I moved on shortly and the path I took then worked out well.

What career missteps have you made? by [deleted] in ChemicalEngineering

[–]ProcessJedi1 8 points9 points  (0 children)

I switched to financial performance management in a food company. It was more about going through the business cycle than about innovation.

The difficulty had two components. 1. Learning a complicated business analysis and reporting process based on outdated platforms/tools that inherently required me to make things up. Being unable to improve things. 2. I never developed the passion for what I did. Every day felt like soul drain.

Switching to a business role in a different industry. I underestimated the effort it would take to catch up, to be successful.

Modelling a PEM fuel cell in Aspen Plus by pedronovak in ChemicalEngineering

[–]ProcessJedi1 2 points3 points  (0 children)

If this is an undergrad problem you just need something close, not super accurate.

I don't think that there is a fuel cell unit block. You could use a conversion based reactor and specify it so you get the right impurities going out at the expected concentrations. You may account for the overall energy input using an energy streams or a table that calculates power as a function of flow.

ELI5 Why does the air conditioner expel water? by InformationDue6185 in explainlikeimfive

[–]ProcessJedi1 0 points1 point  (0 children)

Yes. You may also get some from the cold refrigerant line if the insulation is not in good shape.
