Method and apparatus for sampling the gaseous content of a liquid
First Claim
1. An apparatus for sampling the gaseous content of a liquid laden with solids, comprising:
- a support frame;
a degassing device mounted on said support frame for degassing sample liquid received therein to obtain a sample of gas of the sample liquid, said degassing device comprising a degassing container having an inlet connection for receiving sample liquid therethrough, a rotary degassing agitator, a discharge nozzle for discharging degassed sample liquid, and means for conducting sample gas from said degassing device for delivery to an analyzing device; and
means for collecting sample liquid from a stream of the liquid and delivering substantially all of the sample liquid to said degassing container, said means for collecting and delivering comprising a pump mounted on said support frame having an input connection and an output connection, a flexible suction tube connected to said input connection, and a motor means mounted on said support frame for driving said pump, said output connection being fluidly connected to said inlet connection of said degassing container, and said rotary degassing agitator being driven by said motor means driving said pump.

Abstract
A method and apparatus for sampling the gaseous content of a liquid laden with solids initially involves sampling the liquid as close as possible to the source of the liquid. A strainer housing having a strainer plate for filtering out debris in the liquid is connected to a suction pump for sucking the liquid into the housing and to the pump. The pump delivers the sampled liquid to a degassing device mounted on a frame with the pump. The degassing device agitates the liquid to liberate gases suspended therein. The gases are then collected from the degassing device so that the gases may be analyzed. A motor mechanism on the frame drives the pump, a rotating agitator in the degassing device and a rotating scraper on the exterior of the strainer plate simultaneously. This method and apparatus are particularly applicable to the sampling of drilling mud from an oil well exploration site for purposes of analyzing the hydrocarbon content of the drilling mud.
