PROCESS AND DEVICE FOR UTILIZATION OF SOOT IN POX PLANTS

摘要

THE INVENTION RELATES TO A PROCESS FOR THE MATERIAL UTILIZATION OF SOOT FROM THE WASTE WATER (3) OF A GASIFICATION APPLIANCE (HEAVY OIL POX) (S) IN WHICH A HYDROGEN-AND CARBON MONOXIDE-CONTAINING (CRUDE SYNTHESIS GAS) (4) IS GENERATED FROM RELATIVELY HIGH-BOILING HYDROCARBONS BY PARTIAL OXIDATION, AND ALSO A DEVICE FOR CARRYING OUT THE PROCESS. THE SOOT-LOADED WASTE WATER (3) FROM THE HEAVY OIL POX IS MIXED WITH NAPHTHA (10) AND IS SUBSEQUENTLY INTRODUCED INTO A SEPARATOR (DECANTER) (D, D1) FROM WHICH A SUBSTANTIALLY SOOT-FREE WATER FRACTION (13, 20) AND A SUBSTANTIALLY WATER-FREE NAPHTHA/SOOT MIXTURE (12, 17) ARE TAKEN OFF SEPARATELY, WHEREIN THE NAPHTHA/SOOT MIXTURE (12, 17) IS FED AS FEED TO A FURTHER GASIFICATION APPLIANCE (NAPHTHA POX) (N), IN WHICH APPLIANCE PREDOMINANTLY NAPHTHA IS CONVERTED INTO A CRUDE SYNTHESIS GAS (9) BY PARTIAL OXIDATION.
