ESTIMATION METHOD OF ASSOCIATED GAS ENRICHMENT, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC G01N35/00 

FIELD: oil and gas industry.

SUBSTANCE: quantitative estimation of hydrocarbon component content is identified against specific caloric efficiency on which value intensity of colour shades in the flame plume of fired gas mixture determined as per RGB colour model. When gas mixture cannot be fired with hydrocarbon components due to insufficient percentage of hydrocarbons, the known quantity of hydrocarbon gas sufficient for firing of the gas mixture. By adding measured portions of hydrocarbon gas with the known specific calorific efficiency intensity of colour shades in the flame enriched in the above method by hydrocarbon gas of the gas mixture. Against changes in colour shades of the flame both percentage of hydrocarbon components in the gas mixture and hydrocarbon content are identified when the initial gas mixture cannot be fired. Efficiency of associated gas enrichment is judged against comparison of hydrocarbon components content in associated gas before its delivery to the enrichment plant and at the plant output.

EFFECT: possibility of qualitative and quantitative identification of hydrocarbon components in associated gas, efficiency of associated gas enrichment.
