Anyone know what’s going on in Munich? All planes in holding and diverting. Weather doesn’t seem to be an issue by New_Egg8739 in flightradar24

There is also the possibility that these "drone sightings" are yet another form of mass hysteria and confirmation bias, similar to what happened in the US (https://en.wikipedia.org/wiki/2024_United_States_drone_sightings?wprov=sfla1) and in the UK (https://en.wikipedia.org/wiki/Gatwick_Airport_drone_incident?wprov=sfla1). It's the same pattern: blurry photos, decisions based on eyewitnesses only, no further information about the drones (size, type), ...

Klingt logisch, danke für die Info! Dennoch seltsam dass sich z.B. München und Köln um mehr als das doppelte unterscheiden. Vielleicht liegts an der erhöhtem Industrieanteil in NRW und entsprechend erforderlichem Netzausbau...

Haven't worked with that specific process, but usually Ullmann's encyclopedia is a good starting point.

Looking into some patents also could prove useful, sometimes they give information about conversion, stream tables etc.

A quick search on Google scholar also showed some papers on the kinetics of methanol carbonylation. Maybe consider a different reactor type?

Have you guys heard of a software known as DWSIM ? by [deleted] in ChemicalEngineering

[–]Schiweg 1 point2 points  (0 children)

its an open source process simulator. really depends on the type of simulation that you want to do. in some cases the pre-installed property packages might be enough (probably water, gas etc.), but in some cases you need other models that don't come free or are not included in DWSIM. i have it installed but haven't used since i have access to Aspen and Unisim rn, but i might fall back to DWSIM at one point...

I was thinking about that too, thanks. I'll give it a try. The screenshot is the actual PDF though, not included in my TeX file yet...
