A window and cooling plenum for use with x-ray devices. The x-ray device includes an x-ray tube at least partially immersed in coolant contained within a reservoir. The coolant is continuously circulated through the reservoir by an external cooling unit. The window is brazed into a vacuum enclosure of the x-ray tube and includes a plurality of extended surfaces that are integral with the window. A compensating window is also provided and is disposed substantially proximate to the extended surfaces of the window so that a fluid passageway is defined. The compensating window and window are substantially enclosed within a cooling plenum having fluid inlet and outlet connections in fluid communication with the fluid passageway and the reservoir. A flow of coolant generated by the external cooling unit enters the fluid passageway so that the coolant is able to absorb heat dissipated by the window. Upon exiting the fluid passageway, the coolant returns to the reservoir to repeat the cycle. In addition to facilitating definition of the fluid passageway, the compensating window includes extended surfaces and slots which serve to attenuate differences in the intensity of x-rays emitted through the extended surfaces and slots of the window. By ensuring that the x-rays ultimately emitted from the x-ray device are of substantially uniform intensity, the compensating window serves to maintain the quality of diagnostic images produced by the x-ray device.

Methods for removing sulfur from hydrocarbon streams using the sequential application of hydrodesulfurization, fractionation and oxidation. The hydrodesulfurization step is operative to remove easily-hydrogenated sulfur species, such as sulfides, disulfides and mercaptans. The resultant stream is then fractionated at a select temperature range to generate a sub-stream that is sulfur-rich with the sulfur species resistant to removal by hydrodesulfurization. The sub-stream is then isolated and subjected to an oxidative process operative to oxidize the sulfur species to sulfones or sulfoxides, which may then be removed by a variety of conventional methods, such as absorption. Alternatively, the methods may comprise using the sequential application of fractionation to generate a sulfur-rich sub-stream followed by oxidation and subsequent removal of the sulfur species present in the sub-fraction. The latter methods are ideally suited for transmix applications.
