  • Process and apparatus for extracting sulfur compounds in a hydrocarbon stream
    Patent number: 9328294
    Abstract: One exemplary embodiment can be a process for extracting sulfur compounds in a hydrocarbon stream. The process can include feeding a hydrocarbon stream containing sulfur compounds to a prewash zone containing an alkali, withdrawing a prewashed hydrocarbon stream from the prewash zone, and feeding the prewashed hydrocarbon stream to a mass transfer zone for extracting one or more thiol compounds from the prewashed hydrocarbon stream. Often, the mass transfer zone includes a hollow fiber membrane contactor.

  • METHODS AND APPARATUSES FOR REMOVING IMPURITIES FROM A GASEOUS STREAM
    Publication number: 20150251134
    Abstract: Methods and apparatuses are provided for removing impurities from a gas. A method includes feeding a gaseous stream through a vapor side of a first membrane contactor, and then feeding the gaseous stream through the vapor side of a second membrane contactor. An absorption solution is fed through an absorption side of the second membrane contactor, and then fed through an absorption side of the first membrane contactor. The absorption solution is cooled between the second membrane contactor and the first membrane contactor.
