    Abstract: A system and method for conditioning of very low pressure gas samples extracted from a source, heating the samples, boosting the pressure to a level appropriate for analysis, regulating the gas sample temperature and pressure to prevent dew-point dropout from Joules Thompson condensation, and passing the gas sample to an a remotely located analyzer or analyzer array where the electrical power for the pressurizing pump and heated regulator is provided by heat tracing.

    Abstract: A cryogenic liquid sampling system including a chamber having affixed therein a sample pump to pull a cryogenic liquid sample from an external source and an enclosure. The enclosure includes a supply port to receive an input stream of a gas, an input port connected to the chamber via a vacuum line, a sample pump port connected to the chamber via a pump line and configured to feed therethrough gas received at the supply port to the sample pump, a vacuum device connected to the input port and configured to generate a vacuum within the chamber by pulling air from the vacuum line, and processing circuitry to control the vacuum device and the sample pump to perform transfer of a cryogenic liquid sample from the external source to an external device.

    Abstract: A multi-stage pressure regulation system, device and associated methodology for reducing the pressure of gas passing through a gas sample conditioning system. The device and method allow for automatic and/or manual configuration settings for regulating different types of gas having different profiles while still avoiding dew point dropout thereby ensuring accurate sample analysis at a downstream analyzer. The pressure regulating device includes a housing having a core, a vapor sample input port, a plurality of openings on an upper surface, a plurality of pressure regulating valves configured to reduce the pressure of a vapor sample, and an assembly having a base and substantially central stem orthogonal to the base and extending axially therefrom, the stem being disposed within the core.

    Abstract: Systems and methods for generating a Methane number for a compressed natural gas fuel by obtaining compositional data from one or more particular analyzers and applying the obtained compositional data to one or more selectable Methane number generation protocols. The systems and methods can include refining of the compressed natural gas fuel to meet a predetermined Methane number.
