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.

Ridge and gap structures disposed along the periphery of the outer surfaces to allow for easy placement and removal of the pads. A channel is formed around the housing to form an ergonomic gripping surface. A plurality of replacement pads are stored in the interior of the housing.

The present invention provides a mercury removal system and method for effectively removing a mercury component, which is present in a gas stream in an extremely small amount in wet gas cleaning used for coal or heavy oil gasification, petroleum refining and the like. The mercury removal system in wet gas cleaning comprises a water washing tower for introducing therein a target gas containing a mercury component and transferring the mercury component into an absorbing solution, a flush drum (10) for flushing the absorbing solution discharged from the water washing tower to separate the absorbing solution into a gas component and waste water, an oxidation treatment means (1) for adding an oxidizing agent to the absorbing solution at the preceding stage of the flush drum, and a waste water treatment means for subjecting to coagulation sedimentation treatment the separated waste water containing the mercury component at the following stage of the flush drum to dispose of the mercury component as sludge. The present invention also provides a mercury removal method using the above-described system.

Acid mist may be removed efficiently from a gas stream using at least one fiber bed mist eliminator operating at elevated pressure of typically at least 2 bar (0.2 MPa), e.g. at about 4 bar (0.4 MPa) to about 50 bar (5 MPa).

A new regeneration method has been developed which can effectively and efficiently remove sulfur from Ni-based steam reforming catalysts. In its simplest form the present invention comprises the steps of oxidizing a catalyst with a dilute O₂ stream; decomposing the nickel sulfate under inert gas stream and removing sub-surface sulfur under steam reforming conditions. In some embodiments these steps can all be accomplished and the regenerated catalyst be reintroduced to a steam reforming operation in a matter of eight hours or less.

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.
