Self-Scrubbing Coal{trademark}: An integrated approach to clean air. Comprehensive report to Congress, Clean Coal Technology Program
In response to the PON, 33 proposals were received by DOE in May 1991. After evaluation, nine projects were selected for award. One of the nine projects selected for funding is a project proposed by Custom Coals International (CCI) entitled ``Self-Scrubbing Coal: An Integrated Approach to Clean Air.`` This project will provide a commercial demonstration of the Custom Coals Coal Cleaning (CCCC) process for producing Carefree Coal{trademark} and Self Scrubbing Coal{trademark}, as well as full-scale burns of the products in coal-fired utility boilers. The Self-Scrubbing Coal{trademark} project involves the construction of a 350 tons/hr advanced coal cleaning plant that will be designed with a unique blend of existing and new process steps. The Carefree Coal{trademark} produced by this cleaning process will allow many utilities to achieve compliance with the Clean Air Act Amendments (CAAA) sulfur emissions requirements. Deep cleaning alone, however, cannot produce a compliance fuel from coals with high organic sulfur contents. In these cases, Self-Scrubbing Coal{trademark} will be produced. Self-Scrubbing Coal{trademark} is the same as Carefree Coal{trademark} except that the finest fraction from the cleaning circuit is mixed with limestone-based additives and pelletized. These additives react during combustion to remove an additional 70--80% of the sulfur remaining with the clean coal, thus achieving a total sulfur removal of 80-90%.
