Carbon Adsorption for VOCs Activated carbon adsorption is considered a best available control technology by the USEPA and other regulatory agencies. It is widely used in air pollution control applications to remove volatile organic compounds (VOCs) from low to medium concentration gas streams. Carbon adsorption is especially effective when strict discharge concentrations must be met…
Roadway Vertical Alignments Author: Gregory Taylor Roadway vertical alignments are a combination of parabolic curves and connecting tangent grades. Along with the roadway cross section (lanes and shoulders, curbs, medians, roadside slopes and ditches, sidewalks) and horizontal alignment (tangents and curves), the vertical alignment (grades and vertical curves) helps provide a three-dimensional roadway model. Its…
