Design of a tubular reactor instrumentation assembly for conducting thermal decomposition studies

A thermal instrumentation assembly which uses a high‐temperature tubular reactor for conducting gas‐phase thermal decomposition studies of organic substances has been designed. This thermal reactor assembly uses a counterflow heat exchanger in conjunction with a narrow‐bore quartz tubular reactor to obtain precise control over physical factors, such as exposure temperature, mean residence time, and gas‐phase residence‐time distribution. By virtue of the design of this quartz‐ware assembly, gaseous species are subjected to essentially a square‐wave thermal pulse as they pass through the thermal reactor.

Metals and incinerators: The latest regulatory phase

Abstract Recent regulations in the United States controlling emissions of metals and halogen acid gases from boilers and industrial furnaces (BIFs) burning regu

Windmills, incinerators, and siting

Abstract The public reaction to proposals for the siting of hazardous waste disposal facilities results largely from fear and from distrust of technologists. Several case histories are presented with inferences drawn as to possible future actions to reduce the problem.

Industrial Waste Management At the Swedish Facility in Norrtorp

The central industrial waste treatment and disposal facility located at Norrtorp, Sweden is presented. Kinds and quantity of waste, regional collection sites, path of waste through the plant, design of incinerator and operating philosophy are discussed. Emission of process water and its quality along with the continuously monitored incineration parameters is part of this paper as is a comparison of emissions from the Norrtorp operations with those from autos and other sources in the country. Start-up problems are presented along with conclusions on operations to date.

The united states environmental protection agency combustion research facility: A commitment to hazardous waste management

Abstract This article describes the United States Environmental Protection Agency Combustion Research Facility (CRF) located in Jefferson, Arkansas. The program objectives are presented along with a detailed description of the existing facility. A discussion concerning some research conducted to date is presented along with results from the official permit test burn. Future research objectives are presented.

A hazardous waste siting experience

Abstract This article describes experiences in attempting to conduct hazardous waste research at the pilot scale and the difficulties in finding an acceptable setting for the research. A description of events leading up to and the selection of the site for the USEPA Combustion Research Facility is presented.

Current research on the disposal of hazardous wastes

Abstract The Solid and Hazardous Waste Research Laboratory is one of six laboratories in the Environmental Protection Agency (EPA), National Environmental Research Center at Cincinnati, Ohio. The laboratory is responsible for research into new and improved systems of solid and hazardous waste management, development of technology, determination of environmental effects, and collection of data necessary for the establishment of processing and disposal guidelines. In the past, the laboratory concentrated on problems associated with municipal solid waste; but recently the emphasis has shifted, and present efforts are directed primarily toward the problem of industrial hazardous waste disposal on land. Under the solid waste program, investigations were initiated on the migration of municipal landfill leachate and leachate containment with synthetic liners. These studies have been underway for more than a year, but they will not be discussed here because of the present emphasis on industrial hazardous waste problems. Although none of our research projects is concerned specifically with the disposal of residues and sorbants generated during cleanup of hazardous material spills, much of the forthcoming information will be applicable to spill-cleanup problems. The extramural projects and program areas described here involve many activities that could be useful in spill problems.
