Fremgangsmåte for oksidasjon av organiske spillvæsker |
摘要 |
<p>A method for essentially complete oxidation of concentrated liquors containing oxidable organic matter is disclosed. The following steps are performed under substantial superatmospheric pressure in the method: a feed of the concentrated liquor (8) is brought into direct contact (7) with a hot gas (5) for heating and evaporation of said liquor to produce a final concentrate (11) suitable for oxidation and at a temperature close to its boiling point, and to quench the hot gas to a temperature not more than 100 DEG C above the final conconcentrate boiling point at the prevailing superatmospheric pressure, the final concentrate (11) is oxidised (1) essentially completely at a temperature of at least 800 DEG C with a gas (13) containing at least 60 per cent by volume of oxygen resulting in a suspension of hot gas (5) and molten slag (6), and the molten slag is separated (6) from the hot gas and dissolved in water (15).</p> |
