  • Publication number: 20200308086
    Abstract: A process for producing olefins by cracking paraffins in the presence of methane. In the conventional steam cracking processes for olefin production, steam is used as a diluent in the feed mixture to the thermal cracker. In the processes provided herein, methane replaces steam as a diluent in the feed mixture to the thermal cracker. Replacing steam with methane as a diluent has a potential for cost savings in the construction and operation of a thermal cracking plant for olefin production. In addition, it leads to a much simpler cracking process compared to the conventional steam cracking technology as in the state of the art.

  • Publication number: 20200174142
    Abstract: The present disclosure provides a system and method for efficiently mining multi-threshold measurements acquired using photon counting pixel-array detectors for spectral imaging and diffraction analyses. Images of X-ray intensity as a function of X-ray energy were recorded on a 6 megapixel X-ray photon counting array detector through linear fitting of the measured counts recorded as a function of counting threshold. An analytical model is disclosed for describing the probability density of detected voltage, utilizing fractional photon counting to account for edge/corner effects from voltage plumes that spread across multiple pixels. Three-parameter fits to the model were independently performed for each pixel in the array for X-ray scattering images acquired for 13.5 keV and 15.0 keV X-ray energies. From the established pixel responses, multi-threshold composite images produced from the sum of 13.5 keV and 15.

  • Patent number: 10662100
    Abstract: Provided is an ordered step-wise method for the chlorination and photodestruction of MC-LR contamination of an aqueous liquid such as a potable water supply infested with blue-green algae (cyanobacteria). It has been found possible to usefully chlorinate the water at lower chlorine:MC-LR ratios as compared to known methods and then to irradiate the water with ultraviolet radiation to photolyze the chlorinated MC-LR. The methods incorporate the prechlorination of a cyanotoxin, more advantageously a microcystin, and most advantageously MC-LR, to enhance UV-induced photodegradation of this compound.
