Methanol Cracker
Description:
Beside
endothermic
gas
or
endo
gas,
more
and
more
methanol
is
used
for
the
thermal
treatment
of
metals
as
a
protective
gas.The
methanol
is
directly
insirted
into
the
furnace
and
cracked
there.
CH3OH

H2
Carbon
monoxid
and
hydrogen
are
formed.The
methanol
cracking
gas
is
an
excellent
carrier
gas.
Hydrogen
and
carbon
monoxide
are
reducing
agents
and
avoid
oxidation
or
corrosion
of
metal
surfaces
in
a
furnace.It
has
to
be
taken
into
account
however,
that
carbon
monoxid
increases
the
carbon
content
of
steel.
Methanol
cracking
gas
can
therefore
be
used
for
surface
hardening
of
steel
by
carbonisation
or
carburization.
Carbon
concentration
can
be
increased
up
to
the
saturation
level
of
austenite
in
surface
close
areas
(around
1mm
deep).In
order
to
control
the
carbonization,
water
vapour
can
be
added
or
nitrogen
can
be
used
for
dilution.

Characteristic:
1.Methanol
is
more
expensive
compared
to
Methane,
however
total
costs
for
methanol
cracking
is
lower.
2. Lower
investment
costs.
3. Less
energy
consumption.
4. Less
maintenance.
