Hydrogen sulfide (H₂S) is a naturally occurring chemical and can make up to 28% of natural gas. Characterized by its rotten egg odor, the gas can be detected at low concentrations. Also colorless, the gas can be lethal when exposed to high concentrations. Such levels desensitize the nose, making individuals unaware of the danger that they are in.
Hydrogen sulfide and several other factors contribute to the embrittlement of pipelines. This occurs as the gas reacts with and dissolves in the metal of the pipeline, causing cracks. Weakened pipelines can rupture and spew gases into the atmosphere.
To protect pipelines from embrittlement and personnel from the lethal effects of H₂S in the natural gas industry, accurate measurements of H₂S are imperative. As a result of this, Advanced Instruments Inc. now offers a full line of H₂S analyzers for measuring trace levels of H₂S in flowing gas streams and ambient air.
Through the implementation of advanced galvanic electrochemical sensor technology, Advanced Instruments Inc.’s H₂S analyzers provide accurate measurements at low cost and with little to no maintenance required. The H₂S sensors are specific to H₂S and generate an electrical signal proportional to the amount of H₂S present in the gas stream. The H₂S analyzer series features state-of-the-art electronics to achieve the most reliable and accurate measurements of H₂S.
The GPR-7500 AIS is an analyzer with two user-configurable alarms and the GPR-7500 IS is a two wire loop powered transmitter. Both units have a sample conditioning system consisting of a coalescing filter, flow meters, sample/ span valve and air pump and are ATEX certified intrinsically safe for use in hazardous areas. With 4-20 mA or 1-5 V analog outputs, the units provide real time continuous measurements. This eliminates the errors associated with individual observation and interpretation.
The GPR-7100 is a portable H₂S analyzer. Like the GPR-7500 AIS and IS, the GPR-7100 includes a coalescing filter, flow meter and air pump and is ATEX certified intrinsically safe for use in hazardous areas. The unit has a NEMA 4X enclosure designed to withstand the rigors of work in the field.
Optional equipment is available to customize the GPR-7500 AIS/ IS and GPR-7100 to your specific application, including a high PPM H₂S sensor capable of measuring up to 2000 PPM.
