Description:
The paper gives results of inhouse emissions testing and a literature review relating to Orimulsion, an emulsion of Venezuelan bitumen, water, and a proprietary surfactant, being used as a fuel for utilities in Canada, China, Denmark, Italy, Japan, and Lithuania, primarily as a replacement for heavy fuel oil. In 1997, the U.S. Congress directed the EPA to examine the environmental impacts resulting from the use of Orimulsion as a fuel. In response, EPA's National Risk Management Research Laboratory is conducting a study of air pollutant emissions from Orimulsion combustion, based on a externally reviewed technology assessment plan. The plan includes collection and review of previously reported data, EPA inhouse combustion and toxicology testing, and environmental assessment to be conducted by EPA's National Center for Environmental Assessment and, where possible, testing of full-scale units operating with Orimulsion. The inhouse combustion testing measured emissions of carbon monoxide, carbon dioxide, oxides of nitrogen, particulate matter, sulfur dioxide, sulfur trioxide, and several metals. Measurements were made or Orimulsion and a high-sulfur heavy fuel oil to provide a basis for comparison.
