Results are given of a detailed engineering evaluation of the potential for using an absorption on spent shale process (ASSP) for controlling sulfur emissions from oil-shale plants. The evaluation analyzes the potential effectiveness and cost of absorbing SO/sub 2/ on combusted spent shale in either a fluidized-bed combustor (FBC) or a fluidized transport system (lift pipe) for three retorting processes: Lurgi (lift pipe), Union C (FBC), and Modified In-Situ (FBC). Conceptual designs were completed for the three retorting processes, and the costs of removing SO/sub 2/ by the ASSP approach were compared to the costs of removing either H/sub 2/S (including other sulfur species such as mercaptans and thiophenes) or SO/sub 2/ by the leading conventional sulfur removal processes. A number of significant process variables were identified and evaluated. Study results indicate that ASSP is technically and economically viable compared to conventional technologies for most retorting processes.
