Use of Coal Combustion By-Products as Low-Permeability Liners for Manure Storage Facilities
This chapter presents an overview of the use of compacted flue gas desulfurization (FGD) material as a low-permeability liner. It discusses the engineering characteristics of FGD materials...
Marine Engines Emissions for Vessels of the United States Coast Guard
A source testing project was conducted for a select class of ships of the United States Coast Guard (USCG). Pollutants quantified included nitrogen oxides (NOX), sulfur dioxide (S02),...
Production of Lunar Concrete Using Molten Sulfur
A study has been undertaken by the authors and supported by NASA to study the feasibility of using lunar regolith with different binders such as molten sulfur, epoxy or hydraulic cement...
Caustic Spray for Sewer Crown Corrosion Control
A novel method to control sewer crown corrosion which involves spray application of a caustic solution to the sewer crown is described. Corrosion control using this concept is based on...
Present and Future Use of Coal Ash in Construction and Related Applications
The American Coal Ash Association, Inc. (ACAA) is an organization of producers and marketers of coal combustion by-products. An annual survey of coal-burning electric utilities is conducted...
Sulfur as a Lunar Resource
Sulfur on the Moon may prove to be a satisfactory replacement in some uses for lighter volatile elements and their compounds. Although sulfur is not richly concentrated on the Moon, it...
A Modified Sulfate Process to Lunar Oxygen
A modified sulfate process which produces oxygen from iron oxide-bearing minerals in lunar soil is under development. Reaction rates of ilmenite in varying strength sulfuric acid have...
Offshore Challenge
Standard design techniques weren't enough to create rigs for the Main Pass Mine, which, at 67 million long tons, is the largest offshore sulfur mine in U.S. history. The 18...
Structural Renovation of Tall Chimneys
This paper describes several tall chimney projects where major renovations were performed to the linings which required complete structural analysis of the existing chimney and foundation....
Optimization Models for Acid Rain Control
A series of related optimization formulations are presented for developing and analyzing acid rain control strategies. These models span a wide array of approaches and reflect a similarly...
Screening Emissions Control Measures
Under the new Clean Air Act, electric utilities will be able to choose from a wider range of sulfur dioxide emissions control options than in the past. Among the newly available measures...
Gas Transfer Velocities on Lakes Measured with Sulfur Hexafluoride
Gas transfer velocities have been determined on five lakes ranging in size from 0.13 km2 to 450 km2 using...
Beach Evolution in Sulphur Island
Seasonal variation of shore area of Sulphur Island is studied by analyzing aerial photographs of the island taken seasonally for the past two years. Analysis reveals that shore area in...
Sulfur Polymer Concrete for Special-Purpose Applications
Special-purpose sulfur concrete construction materials, based on sulfur polymer cement (SPC) and mineral aggregate, have been developed by the U.S. Bureau of Mines as part of a program...
Power Without Acid
Anticipating tighter acid rain controls, DOE is developing duct injection units that can be attached to existing powerplants. In a typical duct injection system, lime is sprayed into existing...
Sulfur-Based Construction Materials for Lunar Construction
Several approaches have been suggested to use lunar or Martian aggregate in extraterrestrial construction. These approaches include hot pressing of lunar soils producing cements and concretes...
The Political Science of Acid Rain
Emission control engineers must understand the politics and science of acid rain. Current research indicates that acid rain can be connected with lake acidification. But it can not be...
Development of Second Generation Plasticized Sulfur Binders as a Paving Material
Plasticized sulphur is produced when melted sulphur is reacted with selected hydrocarbons to produce polysulfides. These polysulfides help retain a 'polymeric'...
Current Status of Flue GasDesulfurization in the United States
Flue gas desulfurization (FGD) systems have been in existence in the United States for only 17 years but they have made a tremendous impact in the operation of utility plants. At present,...
1981 Clean Air Act Amendments: A Call for Rhyme and Reason
The state of the nation's clean air legislation is reviewed and found lacking common sense; changes to the law are recommended. Significant improvements in air quality for...
