Drilling Fluid Management & Disposal
Drilling fluid waste management and solids control of drilling mud related technical and developed situation.
Degasser mainly talk about: vacuum degasser and poor boy degasser (gas mud separator ) in drilling fluid field.vacuum degasser is front shale shaker settled device in solids control system. Poor boy degasser is safety device for avoid people was damaged by mal-gas in drilling progress.
This section provides additional thoughts and considerations concerning solids-control equipment. The practical operational guidelines for equipment discussed here may not apply to all drilling applications. These guidelines (in italics) were developed as part of API RP 13C. The discussion beneath each captures some of the comments by committee members as they debated the guideline before approval.

Hoppers, mud guns, desanders, desilters, degassers, and triplex pumps requiring supercharging all have one thing in common: they require 76–80 feet of inlet head to operate as designed. Exceptions do exist, and the equipment manufacturer should be consulted. This simplifies the job of sizing centrifugal pumps. Since most applications in drilling systems require 80 feet of head at the inlet of the equipment, knowledge of volume needed by each piece of equipment is required. Following are standard flow rates when equipment has an 80-foot inlet head:

A degasser is a device used in drilling to remove gasses from drilling fluid which could otherwise form bubbles.-wiki
The purpose of a degasser is to remove entrained gas from the drilling
fluid. By this definition, then, the degasser has a limited capability for
handling large quantities of gas—typically anything more than about
50–100 scfm (20 scfm of gas at surface pressure will gas-cut 400 gpm of
16-ppg drilling fluid to 10 ppg). Large volumes of gas need to be
removed first by a separator or gas buster.
