®.
Gas can be
safely piped
directly to
the flare
line as no
air and
oxygen is
entrained in
the gas to
create an
explosive
mixture.
Vessel-type
degassers
have air and
gas mixed.
Fabrication
costs in rig
structures
are greatly
reduced
since
Burgess
Magna-Vac
Degassers®
weigh
one-third as
much as
vessel-type
degassers.
The compact
size of
Burgess
Magna-Vac
Degassers®
saves on mud
room and mud
tank space.
The degasser
has ability
to run dry
with no mud
or low mud
level
continuously
without
harm.
Burgess
Magna-Vac
Degassers®
require
considerably
less piping
than
vessel-type
degassers.
Burgess
Magna-Vac
Degassers®
are equipped
with 20
horsepower
electric
motors. A 60
to 75
horsepower
centrifugal
pump is
required to
operate
vessel-type
degassers.
Fuel cost
savings are
based on 20
horsepower
versus 75
horsepower.
Burgess
Magna-Vac
Degassers®
are closed
to the
atmosphere
and are
capable of
scavenging
the oxygen
from the
mud,
resulting in
lower
corrosion
costs on the
mud system.
Vessel-type
degassers
have to
bleed the
atmosphere
into the
vessel in
order to
control the
vacuum.
Burgess
Magna-Vac
Degassers®
can handle
100 cubic
feet per
minute of
gas. The
vacuum pump
on
vessel-type
degassers
handles only
20 cubic
feet per
minute of
gas.
Burgess
Magna-Vac
Degassers®
can be
controlled
by a single
start/stop
button. They
are
self-regulating
and require
no start and
stop
procedures
like
vessel-type
degassers.
The
vacuum/blower
on Burgess
Magna-Vac
Degassers ®
is capable
of
entraining
mud in the
event of a
mechanical
failure;
simply fix
the problem
and wash out
the
vacuum/blower.
If mud is
entrained at
the positive
displacement
pump of
vessel-type
degassers,
the valves,
pistons and
cylinders
are ruined
and pump
must be
overhauled.
Burgess
Magna-Vac
Degassers®
can be
disassembled
into two
components
and carried
into the mud
room through
a standard
manway door.
If a
vessel-type
degasser is
used, the
floor or
deck must be
cut out to
remove the
unit.
