  • Removal of carbon dioxide from paraffins
    Patent number: 8552246
    Abstract: ETS-10 titanosilicate materials selectively adsorb carbon dioxide from gaseous mixtures containing carbon dioxide and light paraffins such as methane and ethane.
    Type: Grant
    Filed: March 1, 2010
    Date of Patent: October 8, 2013
    Assignee: The Governors of the University of Alberta

  • Removal of ethane from natural gas at high pressure
    Patent number: 8282709
    Abstract: ETS-10 type materials preferentially adsorb ethane and, if present, C3+ paraffins from mixtures comprising methane, ethane and optionally C3+ paraffins at pressures above 200 psia. A process in which ETS-10 type materials are used to separate ethane and C3+ paraffins from natural gas streams at over 200 psia is provided.
    Type: Grant

  • Process for the separation of olefins from paraffins using membranes
    Patent number: 7361800
    Abstract: Chitosan membranes chelated with silver or cuprous material may be used to separate olefins from a mixture of olefins and paraffins. The feed stream is humidified, demisted, treated to remove sulfur compounds and passed to a cell having a chitosan membrane containing chelated silver or cuprous compounds. The process has a reasonable flux rate and is operable at reasonable temperatures and pressures. The process could be used in an olefin separation train.

  • Use of ionic liquids to separate olefins, diolefins and aromatics
    Patent number: 7019188
    Abstract: The present invention relates to the separation of olefins, diolefins and lower aromatics from mixed streams of hydrocarbons using ionic liquids in the absence of metal compounds. The present invention eliminates the metal complexes conventionally used in such separation and thus reduces the complexity of the process.
    Type: Grant

  • Use of ionic liquids to separate olefins, diolefins and aromatics
    Publication number: 20040044264
    Abstract: The present invention relates to the separation of diolefins, and lower aromatics from mixed streams of hydrocarbons using ionic liquids and metal complexes. The present invention provides a novel method to separate diolefins and lower aromatics from other hydrocarbyl streams which may contain small amounts of water.
