Liming efficacy and transport in soil of a dry PFBC by-product

The by-products of pressurized fluidized-bed combustion (PFBC) systems are mixtures of coal ash, anhydrite (CaSO{sub 4}), and unspent alkaline sorbent. Because PFBC by-products are alkaline and contain large concentrations of readily soluble bases (Ca and in some cases Mg) and other essential plant nutrients such as S and K, they have potential use as soil amendments, especially in acidic soils. PFBC by-products (particularly those with large Mg contents) may cause excessively high soluble salt… more

The Carnol process for CO{sub 2} mitigation from power plants and the transportation sector

A CO{sub 2} mitigation process is developed which converts waste CO{sub 2}, primarily recovered from coal-fired power plant stack gases with natural gas, to produce methanol as a liquid fuel and coproduct carbon as a materials commodity. The Carnol process chemistry consists of methane decomposition to produce hydrogen which is catalytically reacted with the recovered waste CO{sub 2} to produce methanol. The carbon is either stored or sold as a materials commodity. A process design is modelled … more

Investigation of the use of fly-ash based autoclaved cellular concrete blocks in coal mines for air duct work. Final report, January 25, 1993--December 31, 1994

Coal mines are required to provide ventilation to occupied portions of underground mines. Concrete block is used in this process to construct air duct walls. However, normal concrete block is heavy and not easy to work with and eventually fails dramatically after being loaded due to mine ceiling convergence and/or floor heave. Autoclaved cellular concrete block made from (70{plus_minus}%) coal fly ash is lightweight and less rigid when loaded. It is lighter and easier to use than regular concre… more

Management of dry flue gas desulfurization by-products in underground mines. The development and testing of collapsible intermodal containers for the handling and transport of coal combustion residues

SEEC, Incorporated, is developing a collapsible intermodal container (CIC{trademark}) designed for containment and transport of fly ash and other dry-flowable bulk commodities. The CIC is specially configured to ride in open top rail cars, but as an intermodal container, it also rides in barges and on flat bed trailers. This allows SEEC to use unit coal train back haul capacity to transport fly ash to markets at and near coal mines. SEEC`s goals for this project were to design a CIC for handlin… more

Reducing biosolids disposal costs using land application in forested areas

Switching biosolids land application from a reclamation site to a forested site significantly reduced the cost of biosolids disposal at the Savannah River Site. Previous beneficial reuse programs focused on reclamation of existing borrow pits. While extremely beneficial, this program became very costly due to the regulatory requirements for groundwater monitoring, soil monitoring and frequent biosolids analyses. A new program was developed to reuse biosolids in forested areas where the biosolid… more

Conversion of coal wastes into waste-cleaning materials. Quarterly progress report, April 1, 1995--June 30, 1995

In the last three months we have studied the ion exchange behavior of the zeolites, converted from fly ash in more detail. In particular, the ion-exchange isotherms of the treated fly ash containing zeolite Y with Cs+ ions were studied. For comparison, the ion exchange isotherms of synthetic zeolite Y and commercial zeolite A were also studied. These results showed that the background materials in the fly ash do not affect the ion exchange performance of the zeolites that the fly ash contains. … more
