3-Pack - H2S, H2O, CO2 Analyzer System

 
The SpectraSensors H2S, H2O & CO2 3-Pack gas analyzer system retains the analytical benefits and reliability known by our existing customers. In addition, reduced installation costs, support and complexity are achieved via a single technology for gas quality measurements.
Product Code: 11715

 


Application Note

Gas Quality Simplified
The analyzer system includes all required sample conditioning and regulation. The sample system is heated to 50°C (122°F) to keep all constituents in vapor phase.

Training requirements are reduced and the system enables fewer electrical runs, fewer sample runs and less labor. Installation and operational costs are dramatically reduced.
 

 

 
The Installation diagram on the left is a simple representation of connection to the pipeline.
 
A variety of sample probe products are available to compliment the application.
 
SpectraSensors offers probes, probe regulators, and heated regulators depending on the pressure in the pipeline, the gas and ambient temperatures and the hydrocarbon dew point.

Sample Conditioning

P53   P53 Heated Sample Extraction System

HEATED SAMPLE CONDITIONING

The P53 Heated Sample Conditioning System ensures performance of gas analyzer by delivering a heated sample through patented technology to the analyzer.

This avoids costly errors resulting from hydrocarbon dew point drop out by the maintaining at least 30ºF above the expected hydrocarbon dew point.

The gas sample is heated inside of the regulator before and after the pressure is reduced eliminating hydrocarbon liquid condensation caused by the Joule Thomson effect during the pressure reduction.

    PONY

    HEATED PROBE ENCLOSURE

    The Pony® Heated Probe Enclosure is designed to provide and maintain heat for the sample probe directly at the sample point with a P53 Heated Sample Conditioning System.

    The Pony® enclosure is an integral part of the P53, developed to install between 6” center-to-center thread-o-lets.

    Consisting of a molded, insulated, and weatherproof clam shell design, the Pony® enclosure provides easy maintenance with steel latches and chain to prevent loss of lid.

    Construction selections include hot press glass fiber reinforced polyester or stainless steel.
