Exploration of Detection Methods for Hydrogen Sulfide in Natural Gas
Among the commonly used methods for detecting H2S,Coulomb method and gas chromatography have long analysis time,complex operation,and high requirements for instrument operation technology,while gas detection tube method has fast detection speed but low accuracy.In order to improve the efficiency and accuracy of H2S analysis,the gas detection tube method was selected for H2S content detection.Through experiments,the best detection conditions were found for the sample gas in terms of outlet flow rate,needle sampling displacement frequency,sample gas storage time,injection time,sampler selection,and environmental temperature.The results showed that under the best detection conditions,the accuracy of H2S analysis by the gas detection tube was improved,meeting the requirements of central control analysis.
