    • The present invention generally relates to systems and methods for providing information about chromophores in physiological media. More particularly, the invention relates to non-invasive systems and methods for determining absolute values of oxygenated and/or deoxygenated hemoglobins and their ratios in a physiological medium. The system generally includes a portable probe having a source module (122) for irradiating into the medium electromagnetic radiation, a detector module (124) detecting radiation from a target area in the medium, and a processing module (140) determining the absolute values of the chromophore concentrations and the ratios thereof based on input and output parameters of the source and detector modules. In one aspect, the invention provides a solution for unknown parameters of the chromophores in a medium using a novel processing algorithm. In another aspect, the invention concerns a portable unit for performing the requisite measurements, which unit includes a movable member having one or more radiation sources and one or more radiation detectors, and an actuator designed to cause the member to move along predetermined curvilinear paths. Properties of the chromophores are measured for individual voxels defined along each motion path, and/or cross-voxels defined at the intersection of voxels along different motion paths. These measured values are then used in a preferred embodiment to generate two- or three-dimensional images of the distribution of chromophores or their properties. In other aspects, the invention includes various patterns for the optimal distribution of sources and detectors for the optical probe, and self-calibrating operation of the probe substantially in real-time.

    • A method and system for capturing hydrogen gas in a refinery is disclosed. The system comprises a first membrane and pre-reformer. The membrane is suitable for separating a refinery fuel gas feed, which includes hydrogen gas and hydrocarbon gases, into a hydrogen gas depleted retentate stream and a hydrogen gas enriched permeate stream. The pre-reformer receives the retentate stream from the first membrane and catalytically converts the retentate stream into an outlet stream of hydrogen and methane gases. The system may further include a reformer which receives at least a portion of the outlet stream and catalytically converts the methane gas into hydrogen and carbon oxides. A second membrane may be used for separating the outlet stream into a second hydrogen depleted retentate stream and second hydrogen enriched permeate stream. The reformer, in this case, receives the second hydrogen depleted retentate stream to provide methane for steam reforming. Because hydrogen is removed from the original refinery fuel gas feed fed to the pre-reformer and/or the outlet stream fed to the reformer, additional hydrocarbons can be fed to the pre-reformer and/or reformer, in place of the removed hydrogen gas, to increase the overall hydrogen gas production from the system.
    • 公开了一种用于捕获炼油厂中的氢气的方法和系统。 该系统包括第一膜和预重整器。 该膜适用于将包括氢气和碳氢化合物气体的炼油厂燃料气进料分离成氢气贫化渗余物流和富氢气渗透物流。 预重整器接收来自第一膜的滞留物流并将滞留物流催化转化成氢和甲烷气体的出口物流。 该系统还可以包括接收至少一部分出口物流并将甲烷气体催化转化成氢和碳氧化物的重整器。 第二膜可用于将出口物流分离成第二贫氢渗余物物流和第二富氢渗透物物流。 在这种情况下,重整器接收第二贫氢截留物流以提供用于蒸汽重整的甲烷。 因为从输送到预重整器的原始炼油厂燃气供给和/或供给到重整器的出口物流中除去氢,可以将另外的烃供给到预重整器和/或重整器,代替除去的氢气 ,以增加系统的总体氢气产量。
