  • Patent number: 10717041
    Abstract: The present disclosure describes a process for separating at least a first gas component and a second gas component by contacting a gas stream comprising the first and second gas components with a carbon molecular sieve (CMS) membrane under aggressive gas separation conditions in which the partial pressure of the selectively sorbed gas component in the gas stream is high. Despite the high partial pressure of the sorbed gas component, the selectivity of the carbon molecular sieve membrane is not substantially reduced by plasticization or saturation. In some embodiments, the aggressive gas separation process may include contacting a gas stream at supercritical conditions with a CMS membrane to separate at least first and second gas components. The process may be useful for, among other things, the separation of CO2 from a natural gas stream.

  • Patent number: 10705252
    Abstract: A Paleo Event Table creator tool box is described which is induced and/or allows a user to spatially join a selected area of interest of the earth crust to one selected tectonic plate in a tectonic plate model, which selected tectonic plate has an overlap with the area of interest, and to sample a paleogeographic dataset relevant to the area of interest for a series of paleogeographic time steps. A graphical user interface is induced and/or allows the user to create a Paleo Event Table that displays the sampled paleogeographic dataset. The Paleo Event Table creator tool box is used for paleogeographic reconstruction of the earth crust in the area of interest and identifying information relevant for the area of interest.
