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. The mercury removal system in wet gas cleaning includes a water washing tower for introducing therein a target gas containing a mercury component and transferring the mercury component into an absorbing solution, a flash drum () for flashing 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 () for adding an oxidizing agent to the absorbing solution at the preceding stage of the flash 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 flash drum to dispose of the mercury component as sludge.

A COS treatment apparatus for a gasified gas includes an Oremoval catalyst and a COS conversion catalyst located on the downstream side of a gasified gas flow with respect to the Oremoval catalyst. Also, a COS treatment apparatus includes a TiOcatalyst that carries CrOor NiO. Further, a COS treatment method includes a first step in which Ois removed by the reaction with HS and CO, and a second step in which COS is converted to HS.

A transmission screen having a writable and erasable surface for one side is provided. This transmission screen is constructed so that the writable and erasable surface should have a specular gloss (JIS K5600-4-7:1999) of 70 to 135%, the transmission screen as a whole should have a haze (JIS K7136:2000) of 80% or more, and the surface opposite to the writable and erasable surface should have a specular gloss (JIS K5600-4-7:1999) of 10% or less. With this transmission screen, writing with a marker for white boards and erasing can be easily done while seeing images projected on the transmission screen, and the images from a projector do not become hard to see due to projection of the images on the body of a writer.

A transparent hard coat film having excellent hardness and transmitted resolution, in which an interference fringe attributable to non-uniform thickness of the transparent hard coat layer is not noticeable, is provided. The transparent hard coat film of the invention has a transparent hard coat layer formed on at least one surface of a transparent polymer film, wherein the transparent hard coat film has a b* value in the L*a*b* color space system of 0.5 or less.

In a vessel () to which waste liquid () which contains ink pigment, water and cleaning liquid used in a printer is supplied, a metal electrode plate () which allows the waste liquid () to flow therethrough is disposed to partition the inside of the vessel () into a first region (a) and a second region (b). A high voltage from a high-voltage power supply () is applied to the metal electrode plate () while a grounding electrode () is connected to the first chamber (a) to generate an electrostatic field between the metal electrode plate () and the grounding electrode () so that the water and the ink pigment are electrostatically agglomerated from the waste liquid () making use of electrophoresis of the ink pigment by the electrostatic field thereby to separate the waste liquid in the first region (a) into the cleaning liquid, water and ink pigment.

A wet gas purification method is provided for removing ammonia from a heavy oil gasification gas, such as coal. The method principally involves a washing step during which absorbent is charged into the gas to absorb ammonia and an ammonia treating step wherein absorbent discharged from the washing step is separated into an effluent and an off-gas containing ammonia. The amount of absorbent charged during the washing step is controlled such that the ammonia concentration of gas exiting the washing step is 10 ppm or less.
