Process and coke recovery plant for the treatment of sulfur-containing process residues from petroleum processing; Petroleum coke formed from sulfur-containing process residues

摘要

The invention relates to a process for the treatment of sulfur-containing process residues from petroleum processing, wherein the process residues are converted into coke in a coke oven. According to the invention, the process residues, optionally with further additives, are comminuted before coking and mixed with calcium carbonate, that the mixture thus obtained is compacted before coking and that a portion of the calcium carbonate with a portion of the contained in the process residues in chemical compounds Sulfur is subsequently converted during the carbonization to calcium sulfide. The invention furthermore relates to the petroleum coke obtainable by such a process and to a coke recovery plant for carrying out the process.
