  • Sour gas and acid natural gas separation membrane process by pre removal of dissolved elemental sulfur for plugging prevention
    Patent number: 8540804
    Abstract: Methods for removing sulfur from a gas stream prior to sending the gas stream to a gas separation membrane system are provided. Two schemes are available. When the sulfur content is high or flow is relatively high, a scheme including two columns where one tower is regenerated if the sulfur concentration exceeds a preset value can be used. When the sulfur content is low or flow is relatively low, a scheme including one column and an absorption bed.

  • METHOD, SOLVENT FORMULATION AND APPARATUS FOR THE MEASUREMENT OF THE SALT CONTENT IN PETROLEUM FLUIDS
    Publication number: 20120293186
    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.
