Oilfield drilling Poor boy degasser that removes air or gases
(methane, H2S, CO2 and others) from drilling liquids. There are two generic
types that work by both expanding the size of the gas bubbles entrained in the
mud (by pulling a vacuum on the mud) and by increasing the surface area
available to the mud so that bubbles escape (through the use of various
cascading baffle plates). If the gas content in the mud is high, a mud gas separator or “poor boy degasser” is used, because it has a higher
capacity than standard degassers and routes the evolved gases away from the rig
to a flaring area complete with an ignition source.
Poor boy degasser is located between
choke manifold and shale shaker, it has a pipeline for discharging gas
directly. According to practical experience, the thruput of poor boy degasser must
be reached five times design circulation. The inner diameter of drilling fluid exit pipeline
should be not less than the inner diameter of inlet pipeline, drilling fluid
will be directly discharged in inlet manifold of shale shaker or mud tanks.
Based upon your predicted operating conditions
and your required gas handling capacity, DC Machinery will be able to calculate the optimal size of your mud gas separator.
All of our poor boy degassers are supplied with a complete calculation package;
this will include mechanical strength calculations, theoretical separation
capacities and safe working pressures etc.
