Abstract:
A self-actuating gas/liquid separator which depends on the counterbalancing f the liquid in a closed container in excess of a certain height and the vacuum gas pressure for its actuation and operation. Primarily this invention was directed to the separation of water and methane gas after they are discharged from an inclined coal mine drainage bore hole. Basically, there are two inclined coaxial conduits, one inside the other, with the inner smaller conduit providing the path for the movement of the gas and the outer larger conduit the path for the liquid. Attached to the larger conduit, near its end remote from the source of gas and liquid to be separated, is a third conduit with a U-shaped section and a one-way liquid passing check valve. Liquids drain into the first and third conduits and the second conduit is operably subjected to a vacuum generating source. Eventually, as the liquids fill their conduit containers, there will come a time when the counterbalancing gas pressure created by the vacuum and the rising liquid level become unbalanced.

Abstract:
A portable tester is provided for reading and displaying the pressure of a gas released from a rock core sample stored within a sealed container and for taking a sample of the released pressurized gas for chemical analysis thereof for subsequent use in a modified direct method test which determines the volume of gas and specific type of gas contained within the core sample. The portable tester includes a pair of low and high range electrical pressure transducers for detecting a gas pressure; a pair of low and high range display units for displaying the pressure of the detected gas- a selector valve connected to the low and high range pressure transducers, a selector knob for selecting gas flow to one of the flow paths; control valve having an inlet connection to the sealed container, and outlets connected to: a sample gas canister, a second outlet port connected to the selector valve means for reading the pressure of the gas from the sealed container to either the low range or high range pressure transducers, and a connection for venting gas contained within the sealed container to the atmosphere. A battery is electrically connected to and supplies the power for operating the unit. The pressure transducers, display units, selector and control valve means and the battery is mounted to and housed within a protective casing for portable transport and use.
