    摘要: The present invention provides a wet gas purification method in which ammonia in the gas is removed, and a system for carrying out said method, characterized in that the method includes a washing step in which ammonia in the gas is absorbed in an absorbent for removal; and an ammonia treating step in which ammonia is stripped from the discharged absorbent at a following stage of the washing step, wherein the absorbent is divided into an off-gas containing ammonia and effluent. In the washing step makeup water is charged continuously or intermittently so that the concentration of ammonia in the gas having passed through the washing step is 10 ppm or lower. According to the present invention, a wet gas purification method can be performed in which the running costs involved in operation is reduced, the manipulation step and system are simple, operation is easy, and the reliability is high.

    摘要: 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.

    摘要: The present invention provides a mercury removal method which can effectively remove very small amounts of mercury components present in a gas during wet gas purification such as coal or heavy oil gasification gas purification and petroleum refining. A mercury removal method for the removal of mercury present in a gas, the method comprising the steps of bringing a gas containing at least mercury and not less than 10 ppm of hydrogen sulfide into gas-liquid contact with an absorbing fluid under pressurized conditions so as to cause mercury to pass into the absorbing fluid; flashing the mercury-containing absorbing fluid under lower-pressure conditions to separate it into gaseous components and liquid components; and removing the mercury contained in the separated gaseous components by adsorption to an adsorbent.

    摘要: 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.
