    Hydrotreater - cost of +1 deg inlet temp

    Dear all, I'm looking for a way to quantify the cost to increase a hydrotreater inlet temp by 1 degree. Specifically, I am at a loss of how to correlate the megwatts per ton of feed required to heat up +1 degree to the cost of the associated fuelgas per ton reactor feed. I am not working in...

    Global vs detail oriented brain

    We all know the anecdotes about micro managers and other detail minded people.

    How will we replace plastics?

    I find it funny how many people wonder what we should do if we run out of oil (economically speaking), while there's a whole range of solutions readily available (GTL, nuclear, fuel cell, hydro, solar, wind...). A much more tricky question IMHO is, how are we ever going the replace LDPE, HDPE...

    Teamwork

    Does anybody have a good example of (even better: recipe for) successful teamwork? My theory (slightly exaggerated of course for the sake of the discussion) is that true efficiency can only be achieved when you do something on your own. A team is a necessary evil to achieve something you can't...
