The method includes providing an adsorbent structure suitable for adsorbing the first component, the structure being of the parallel passage contactor type, and cyclically implementing the following steps. Passing the feed stream through the adsorbent structure thus adsorbing the first component and producing a stream depleted in the first component and enriched in the second component. Heating the adsorbent structure to desorb the adsorbed first component by means of circulating a heating stream enriched in the first component at a temperature suitable for regeneration. And cooling the structure by means of passing through it more than 50% of the stream enriched in the second component produced in the step a).

  • Patent number: 8805809
    Abstract: According to one embodiment, an apparatus stores a plurality of datapoints. A datapoint comprises a first value and a second value that depends upon the value of the first value. The apparatus associates the datapoint with a group from a plurality of groups. The group is associated with an identifying range and the datapoint is associated with the group based at least in part upon the first value of the datapoint and the identifying range of the group. The apparatus calculates a median of the second values of the datapoints associated with the group and a performance value by performing a regression based at least in part upon the identifying range and the calculated median of the group. The apparatus determines that the performance value exceeds a baseline value and in response, presents, on a display, an illustration depicting the identifying range and the associated median of the group.

  • Patent number: 8583408
    Abstract: An enhanced modeling tool associated with an entity may facilitate end-to-end modeling of problems in any application space. The enhanced modeling tool may collect modeling data from a variety of sources, check the collected data, find the best predictor variables for a given target variable, estimate the model, implement the model, and validate the model. The output of each of these steps may be in a standardized format to allow other steps to directly incorporate the output. An additional feature of the system may include a reporting capability that generates supporting documents related to model governance and risk compliance.
