Partial oxication of sewage sludge. |
摘要 |
<p>Municipal sanitary sewage sludge is disposed of by an improved partial oxidation process without polluting the environment. Aqueous slurries of sewage sludge are upgraded by being sheared without heating, concentrated if necessary, and then mixed with a supplemental fuel, preferably coal. In one embodiment, the aqueous slurry of sewage sludge and the supplemental coal and/or petroleum coke are introduced into a shearing mixer for simultaneous shearing and mixing together. A pumpable aqueous slurry of sewage sludge-coal and/or petroleum coke is thereby produced having an increased amount of total solids and an increased heat content (HHV) as well as containing an increased amount of sewage sludge for reacting with free-oxygen containing gas in a free-flow partial oxidation gas generator. Hot quench water or steam produced by cooling the hot raw effluent stream of synthesis gas, reducing gas or fuel gas from the gasifier may provide heat for indirect heat exchange with other streams in the process.</p> |
