Basic Unit Operations in Process Engineering Video Lecture | Chemical Technology - Chemical Engineering

and finally let's talk about some unit
operations it's a basic process step in
a chemical engineering process the unit
operation in Bob almost always physical
change or chemical transformation you
don't have none of these you are not
having a unit operation so always
remember physical or chemical change
example separation is physical
crystallization is physical evaporation
is physical filtration is physical
polymerization is chemical is
summarization is chemical and other
reactions already its chemical from
Mighty Wikipedia now let's see some unit
operations I put them here red you can
see the ones about retro engineering
which is actually just a reactor
anything that reacts you can call a
retro so that's where now let's see the
heat operation units
what do you can use for heat transfer
you can either condense evaporate or
simply exchange it this is more like
increase or decrease temperature this is
to change liquid to gas and this one is
to change the gas to liquid you call
also have a freezer etc now let's
continue with the mass operations which
is the most large section cube and we
have crystallizer filter cyclone any
separator any mixer a distillation
column absorption which is not the same
as adsorption okay just remember that
apps and app is a totally different
stuff so take care and finally we see
some operation integration of momentum
which are in general pumps compressors
and maybe a storage tank so just keep
those in mind and you will get the idea
what unit operations we
but in mass balance we're going to see a
lot of unit operations so don't worry
just you have doubt just check what the
unit operation is if I tell you I'm it's
a dryer and you don't know what's a
dryer how does a dry operate just check
have an example how do you see these in
I don't know in the school in the books
very nice you can see actually
everything and the problem is when you
get to the real life you don't see that
much you don't see outside some tubes
here maybe inlet but you don't know like
where all these here and here is the
same here you'll see the column for head
and button and you will see also here
the in real life you'll see a lot but
here you don't see that much but there
are many many stuff here actually there
there's some sky laters for men mmm you
take change oh sorry last one was
distillation column which is mass
transfer heat exchange will be simply a
tube heat exchanger which is many tips
go here you will see that in mass and
energy in heat transfer plus you see it
but the idea is it comes filled like
this and the other fluid goes through
the tube stays on touch basically one
goes inside the tube and the other one
goes outside the tube so they are
touching each other here the real life
well this one is very nice you can you
can actually see the tubes but your real
one life you will see only like this
huge pipe you will see like a rod I
thought it was a pipe not a heat
exchanger and since your fuel pump which
is the momentum one okay diagram picture
you will see simply this or even
something like this but in real life you
will see like there's a motor here and
just Inlet then it goes out
