Safety - the most important feature of Burgess Magna-Vac Degassers.
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.
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-scheduling 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.
