  • Method, solvent formulation and apparatus for the measurement of the salt content in petroleum fluids
    Patent number: 9448221
    Abstract: A method and apparatus for determining the salt concentration of crude oil using a single solvent that allows for improved safety and accuracy. The apparatus can include a pair of electrodes, a solvent storage container, a power source, a temperature sensor, a computer, and a display device. The method includes introducing a volume of the crude oil and a solvent to a mixing zone and mixing them together to form a homogenized mixture. The temperature and conductivity of the homogenized mixture are measured in order to determine the salt concentration of the homogenized mixture, and subsequently, the salt concentration of the crude oil.

  • SULFUR RECOVERY PROCESS FOR TREATING LOW TO MEDIUM MOLE PERCENT HYDROGEN SULFIDE GAS FEEDS WITH BTEX IN A CLAUS UNIT
    Publication number: 20150298972
    Abstract: An enrichment apparatus and process for enriching a hydrogen sulfide concentration in an acid gas stream to create a hydrogen sulfide rich stream for feed to a Claus. The enrichment apparatus comprises a hydrocarbon selective separation unit operable to separate the acid gas stream into a hydrocarbon rich stream and a purified acid gas stream, wherein the acid gas stream comprises hydrogen sulfide, carbon dioxide, and hydrocarbons, a hydrogen sulfide selective separation unit operable to separate the purified acid gas stream to create the hydrogen sulfide rich stream and a hydrogen sulfide lean stream, the hydrogen sulfide rich stream having a concentration of hydrogen sulfide, and the Claus unit operable to recover sulfur from the carbon dioxide lean stream. The enrichment apparatus can include a carbon dioxide selective separation unit in fluid communication with the hydrogen sulfide selective separation unit, operable to separate the hydrogen sulfide rich stream.
