IsoTherming: Hydroprocessing Technology Video Lecture | Chemical Technology - Chemical Engineering

welcome to a whole new way of looking at
hydro processing with conventional
technology here's what happens
feedstock flows in and mixes with
combined make up and recycle hydrogen
flows through a two-phase trickle bed
reactor packed with catalyst the
two-phase reactor affluent flows to a
hot high-pressure separator liquid
reactor affluent exits the bottom of the
hot high-pressure separator while the
overhead flows to a high pressure
condenser to a cold high pressure
separator to a high pressure amine
scrubber then back to the recycle gas
compressor but there's a better way
let's say the feedstock mixes with a bit
of make up hydrogen and flows through a
single phase isothermal reactor then as
the liquid only affluent exits the
reactor a pump recycles some of it to
mix with the feedstock while the
remaining affluent is further separated
welcome to a whole new way of looking at
hydro processing isothermic technology
is a safer more cost-effective
alternative to conventional hydro
processing with no recycled gas
compressor and up to 50% op X savings
isothermal offers a reliable and robust
high performance technology for improved
yields extended catalyst life high
energy efficiency minimal emissions and
a smaller overall footprint key to the
efficiency of isothermal is what goes on
in and around the reactor an isothermal
reactor is different from a trickle bed
reactor in important ways a trickle bed
reactor depends on near perfect
feedstock distribution throughout the
catalyst bed to maximize reaction
efficiency and avoid overheating and
coking in an isothermal reactor a single
phase feedstock saturates every square
millimeter of catalyst and operates with
a lower reactor temperature rise
minimizing coking and overheating
reaction efficiency remains consistently
high
an equally important feature of
isothermic technology is the sealless
recycle pump that delivers excess
hydrogen to fresh feedstock before it
enters the reactor the extremely
reliable pump eliminates the need for a
recycled gas compressor and uses about
10% of the energy all this sounds good
but will isothermal technology work in
fact it's working now
isothermal technology is already
commercially proven in units producing
up to 78 thousand barrels a day more
than 20 refineries worldwide have
adopted the technology for grassroots
and revamp applications that include
diesel hydro treating kerosene hydro
treating FCC feed hydro treating mild
hydro cracking dewaxing
trans mix hydro treating gas to liquid
upgrading it's easy to see why
isothermic technology is the way of the
future we invite you to experience the
