Sulfur-emission-control technology for coal-conversion plants. [List of 60 processes with uses, brief description and flowsheet; 63 references]
The degree of commercialization and the industrial applications of each control technology are summarized in Table 2. The technologies which have been used or planned for coal conversion facilities are listed in Table 3. The Chiyoda Thoroughbred 101 was the most used process for flue gas SO/sub 2/ control, followed by the Citrate process. Both are recovery processes. However, throwaway processes are much more common for flue gas desulfurization. Therefore, both the dual alkali process and a conventional lime/limestone process should be included when evaluating control technology options. Thus, the SO/sub x/ removal processes recommended for further study are: (1) Chiyoda Thoroughbred 101; (2) Citrate; (3) generalized dual-alkali (e.g., CEA-ADL); and (4) conventional lime/limestone scrubbing. From Table 3, the Rectisol, Stretford, Benfield, Selexol, Claus and Amoco sulfur recovery processes were most often chosen for acid gas removal and sulfur recovery. These processes are all widely commercialized. For tail gas clean-up from sulfur recovery plants, the SCOT, IFP, Beavon and W-L SO/sub 2/ recovery processes were most often specified for coal conversion facilities, as shown in Table 3. They are all fully commercialized and applicable technologies, as shown in Table 2. The control technologies selected for further detailed examination cover the general types of sulfur control schemes potentially applicable to coal conversion facilities. Further, they are all commercially available.
