Mustang Sampling has a long history of LNG sampling and continues to provide best-in-class technologies for small and large scale LNG custody transfer. The patented Mustang Sampling Vaporizer provides the core for a variety of sample conditioning systems designed specifically for cryogenic service. Mustang Sampling provides LNG Import & Export Custody Transfer solutions globally, peak shaving solutions, complete bunkering systems and LNG load rack solutions (truck transport).
Wastewater treatment plants typically produce methane-rich gas from the anaerobic decomposition of waste solids, sludge, or biosolids in the municipal wastewater. Constituents of Concern (COCs) such as metals, sulfur compounds, and siloxanes may be present in the gas because these materials are present in waste streams. With processing to increase the methane content, reduce water, and remove COCs, wastewater treatment plants are able to produce RNG that meets tariff requirements for injection into natural gas pipelines. Continuous monitoring thereafter and periodic onsite sampling before injection into the natural gas pipeline insures a reliable future supply.
The final gas quality is measured at the interconnect between the RNG plant and Southwest Gas’ natural gas pipeline. The continuous monitoring begins by extracting an RNG sample through a probe housed in the Pony Heated Probe Enclosure. The extracted gas is transferred via the patented Mustang® Heat Trace Tube Bundle to a Mustang P53® Sample Conditioning System which maintains the temperature of the sample well above the hydrocarbon dew point. The representative sample is distributed using a Musang Modular Sample Control Panel to various analyzer within a Mustang Sampling industrialized building . The RNG feed is typically monitored continuously for CH4, CO2, H2S, nitrogen, and oxygen to make sure it meets the tariff parameters set by Southwest Gas. Safety mechanisms at the interconnect allow the pipeline to reject any RNG not meeting standards into the natural gas pipeline.
To confirm the quality of the cleaned biogas, the Mustang® Biogas Sampling System will sample the gas prior to and after the gas cleaning process. This begins at the sample probe located in the raw gas pipeline. The sample tubing and the sample conditioning panel are electrically heated to slightly above the sample dew point to prevent loss of any gas components. Analyzing prior to and after the gas cleaning will help determine the performance of the cleaning process and also determine the scheduling of the filter media cleaning and or replacements.
