Abstract: A rapid and continuous separator or equilibrator to separate a gas from a liquid includes a venturi and injector, a mixer and a free overfall stream to separate a gas from a liquid. The injector introduces a carrier medium into the liquid which provides a reservoir for the gas to diffuse into as the liquid and carrier make a single transit through the apparatus. The separator was developed to enable real-time estimation of methane concentrations in ground water during purging. Real-time monitoring allows evaluation of trends during water well purging, spatial trends between water wells, and temporal comparisons between sampling events. These trends may be a result of removal of stored casing water, pre-purge ambient borehole flow, formation physical and chemical heterogeneity, or vertical flow outside of well casing due to poor bentonite or cement seals. Real-time information in the field can help focus an investigation, aid in determining when to collect a sample, save money by limiting costs (e.g.

Abstract: A two phase gas-liquid separation apparatus is provided that shapes the flow in a flow shaping line. Shaping the two-phase flow allows centrifugal force to send the heavier, denser liquid to the outside wall of the flow shaping line and allows the lighter, less dense vapor or gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall of the flow shaping line, an exit port on the inner wall will allow for the majority, if not all, of the gas, along with a low amount of liquid, to be sent to a conventional separator. A high ratio of vapor/liquid at a flow rate much lower than the total flow rate within the flow shaping line is sent to the conventional separator. This allows for efficient separation of the vapor from the liquid with the use of a smaller conventional separator.
