Abstract: A gas trap liberates subterranean gases entrained in drilling muds. The trap introduces a stripping gas into a flow of mud gas for liberating mud gases. The trap comprises a pair of opposing truncated right circular vessels and having a concentric bottom mud inlet, a side mud outlet and a gas collection port in the freeboard area, at the top. A stirrer depends vertically into the trap. The stirrer has radial tubes extending from its lower end and inlet ports at its top end for forming a continuous bore and flow passage therethrough. The radial tube ends are bevelled on the trailing edge. The trap is partially immersed in mud forming a mud level in the trap and a freeboard area above containing air. When rotated, the hollow shaft spins the mud, establishing a flow through the trap and forming a turbulent low pressure area at the bevels, drawing air down the shaft from the upper ports and injecting stripping air into the mud, all of which aids in liberating gases from the mud.

In a preferred embodiment, hydrogen sulfide produced with geothermal fluids is converted into hydrochloric acid, which is then used to reduce pH and control scale formation during the extraction of energy from geothermal fluids in a geothermal power plant.

Abstract: The system removes contaminating gases, such as radon, from water using a bubbling action. Contaminated water is sprayed together with air through a duct to a bottom region of a bubbling container. The water and air move generally in the same direction through the system, allowing the flow rate to be varied while maintaining forced air/water contact. The aerated contaminated water bubbles upwardly through the bubbling container and passes through one or more diffusing or mixing plates causing the aerated contaminated water to further break out contaminating gases into the air. At the top region of the bubbling container, the contaminating gases are vented while the decontaminated water flows into a tank. The decontaminated water can then be pumped to a desired location, for example, to a house water system.

Abstract: To collect analyte in a supercritical fluid extraction process, the extractant flows to a collection container under pressure. In one embodiment, the collection container contains collection solvent through which the extractant flows to partition analyte. The extractant adds to the liquid and when the collection solvent-extractant mixture rises to a heating zone, the extractant vaporizes selecively since its vapor pressure is higher than the vapor pressure of the collection solvent. When its pressure exceeds a preset valve pressure it is vented so that extractant continually leaves the collection container. After the extraction is complete, the analyte is concentrated in the collection solvent. In another embodiment, the collection vessel includes a solid material on which the analyte collects. It is removed under pressure by a solvent that is concentrated under pressure.
