Functions of Poor boy degasser for oil & gas
drilling
Poor boy degasser, also called mud gas
separately, it is a normal equipment in mud solids control system for onshore
and offshore rigs. We can see from the name, the main function of poor boy
degasser is to separate gas from drilling mud. There normally big quality air
bubble in the drilling mud. The air bubble may damage the solids control equipment, like mud cleaner, desander,
desilter. Another reason, and the most important reason, there normally dangerous
gas consisted in the air bubble, if it is comes out with mud and spread the environment,
it will make pollution and hurt the operation people at jobsite.
There
mainly 2 types design Poor boy degasser for onshore and offshore oil & gas
drilling.
Design
1: Atmosphere type poor boy degasser
Features
of Atmosphere type poor boy degasser: there will be 5~10 m or more longer vent
line on top of poor boy degasser. It is used to pipe the gas into the
atmosphere directly.
Design
2: Ignition type poor boy degasser
Features
of Ignition type poor boy degasser: Ther dangerous gas in drilling mud is H2S.
It is combustible gas. After fire, it changes out to harmless gas and can be
discharged directly. There will be 50m ~ 100m vent line to guide the gas to
remote area. There will be a flare igniter connected with the vent line and
fire the gas while it comes out.
Flare ignition Device for Poor boy degasser for onshore
and offshore oil & gas drilling
As a
kind of security and environmental protection device, the flare igniter can be
used to make the harmful gas ignited and burned to prevent it pollute
environment. The flare ignition device, apart from being used in the
refinery and gas distribution station, can be matched with Mud
Gas Separator.
