New Shiploading System for Pacific Coast Terminals

Remediation of Nitrate Contaminated Surface Water Using Sulfur and Limestone Autotrophic Denitrification

Air Pollution at the Urban, Regional and Continental Scales

Acidification of Rainwater Due to Washout of Atmospheric Gaseous Pollutants

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),...

Deposition of Atmospheric Pollutants to a Limestone Building

Hydration Mineralogy of Cementitious Coal Combustion By-Products

Tests for Biogenic Sulfuric Acid Corrosion in a Simulation Chamber Confirms the On Site Performance of Calcium Aluminate Based Concretes in Sewage Applications

Sensitized Photooxidation of Dissolved Sulfides in Water
The ability of methylene blue (MB) and riboflavin (RF) to sensitize dissolved sulfides for photooxidation was investigated. Both MB and RF were found to be effective sensitizers for the...

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...

In Situ Recovery of Water from Dormant Comet Cores & CI Carbonaceous Chondrites
Water and volatiles may be produced by drill holes into dormant comet cores or class CI or CM asteroids. This is modeled after in-situ mining as in the Frasch process sulfur mines of the...

FGD Waste Engineering Properties are Controlled by Disposal Choice

The Use of Phosphogypsum-Based Slag Aggregate in Hot Mix Asphaltic Concrete

The Use of Flue Gas Desulfurization Gypsum in Civil Engineering Applications

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...

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...

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...

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....

Projections for Reduction in Lake Acidification From SO2 Emission Reductions
The Acid Deposition Assessment Model (ADAM) is used to assess the possible range of effects of a national acid rain emission reduction plan on lake chemistry and fish populations in the...

Acidic Polysaccharides from Marine Organisms
Different types of acidic polysaccharides have been extracted from various marine organisms. The chemical composition and structural studies of these molecules established that the main...
