Abstract
The concentration of a gas such as hydrogen sulfide in a liquid such as crude oil or other hydrocarbon liquid is measured by conducting a flowstream of the liquid through a jet or eductor type pump for mixing a recirculating vapor stream with the liquid, separating the liquid and the vapor stream in a separator to provide equilibrium conditions between the vapor and the liquid and withdrawing the vapor flowstream for recirculation and remixing with the liquid flowstream while measuring the concentration of the gas in the vapor flowstream. A known flow rate of the gas is added to the combined liquid and recirculating vapor flowstream and the incremental change in concentration of the gas in the recirculating vapor flowstream is measured to determine the concentration of the gas in the liquid flowstream initially. The jet type pump utilizes the liquid flowstream and is in communication with a separator chamber, preferably at atmospheric pressure, for separating liquid from the equilibrium vapor flowstream and recirulating the vapor flowstream through a nonconsumptive concentration detector for the gas. The quantity of gas added to the system is conducted to the pump for mixing with the liquid flowstream by way of a bubble counter type flow measuring device.
