Mustang Intelligent Vaporizer Sampling System® – Model 1

The Mustang Intelligent Vaporizer Sampling System – Model 1 (MIV1®) is a patented technology system designed to vaporize liquid, providing a fresh sample to a continuous online analyzer.  This system is designed with enhanced sample quality, through controlled vaporization, accumulation, and homogenization, accomplished through multiple stages.  For the analyzer to meet its stated accuracy, the MIV1 ensures the sample to the analyzer is stable.  The multi-path design achieves redundancy in large scale LNG and critical areas such as the loading and unloading of ships.

VAPORIZING: The MIV1 is a multi-path design. The MIV1 flash vaporizes liquid samples for introduction into gas analysis systems. Liquid samples are maintained near line conditions until reaching a flash chamber within the vaporizer, preventing pre-vaporization. The energy for vaporization is provided by an electric cartridge heater with sufficiently large surface area to maintain a stable gas temperature throughout the process and send the sample to the Mustang® Accumulator for restructuring.

ACCUMULATING: The Mustang® Accumulator Cylinder is designed with a special mixing wand to aid in the absorption of pressure pulsations and homogenization of gasified LNG.

A vapor return bypass flow control system is controlled by a mass flow controller.  The vapor is sent to the vapor return or flare.

PRESSURE REGULATING: A pre- and post-heated pressure regulator designed to prevent hydrocarbon dew point dropout and reduce sample pressure which is then delivered to the gas chromatograph through a heated sample tube.
