Utilization of combustible components of a tail-gas in the manufacture of carbon black at a high production rate |
摘要 |
The present invention provides an effective means of increasing the production rate of a carbon black process. A hydrocarbon fuel is burned in an insufficient amount of air to support complete combustion to produce a hot gas mixture which produces a tail-gas containing carbon black by the incomplete combustion of a hydrocarbon feedstock. This tail-gas is quenched, the carbon black is removed, and the tail-gas is dried. One or more of the combustible components are removed from the dried tail-gas and from 33 1/3% to 100% of the fuel is replaced with the combustible components so removed. One method of removing carbon monoxide is by contacting the tail-gas with a liquid sorbent comprising cuprous aluminum halide; complexing substantially all of the carbon monoxide contained in the tail-gas; removing the complexed carbon monoxide from the tail-gas; contacting the complexed carbon monoxide with a stripping ligand that forms a more stable complex with sorbents than carbon monoxide, thereby exchanging the stripping ligand for carbon monoxide and recovering the carbon monoxide and a cuprous aluminum halide-stripping ligand containing complex. The contacting steps conducted under substantially anhydrous conditions in the substantial absence of oxygen.
