Six Integrated Gasifi cation Combined-Cycle (IGCC) power plant confi gurations operating on bituminous coal were evaluated and the results are presented in this summary sheet. All cases were analyzed on the same basis, using a consistent set of assumptions and analytical tools. Each gasifi er type was assessed with and without carbon capture and sequestration (CCS). The individual confi guratio...

The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin. Shemshak Formation which is the main coal-bearing sequence was formed during the Triassic-Jurassic in the basin. It consists of sandstone, siltstone, shale and claystone, which variedly al...

In Korea, there are not detailed analysis data on soil contamination in nuclear power plant(NPP) and suitable treatment criteria of contaminated soils. When the soils of NPP were contaminated, they have been simply collected and kept in radioactive waste building. But contamination of soils in NPP is inevitable and enormous amounts of contaminated soils can be produced during decommissioning. T...

Coal seams preserve continuous and high-resolution records of paleoenvironments wildfire events during peat accumulation. In order to elucidate characteristics terrestrial climate changes the time accumulation, petrographic coals in Lower Cretaceous Yimin Formation (Albian) Jiuqiao Sag, Hailar Basin, NE China were studied. petrology analysis shows that studied coal are characterized by dominant...

Background: Chlorophenols are classified as priority toxic pollutants. These acidic organic compounds present a serious potential hazard for human health and aquatic life. Chlorophenols accumulate in water, soil and air due to high stability, and impart an unpleasant taste and odor to drinking water and can exert negative effects on different biological processes. Among the different methods of...

This demonstration project was intended to repower an existing plant facility, the Lakeside Station in Springfield, Illinois. A single Integrated Gasification Combined Cycle (IGCC) process train was planned to generate a net output of 60 megawatts. The plant consists of a combined cycle (gas turbine, heat recovery steam generator, steam turbine) power train located in the existing buildings and...

BACKGROUND Coal burning provides 70% of the energy for China's industry and power, but releases large quantities of polycyclic aromatic hydrocarbons (PAHs) and other pollutants. PAHs are reproductive and developmental toxicants, mutagens, and carcinogens. OBJECTIVE We evaluated the benefit to neurobehavioral development from the closure of a coal-fired power plant that was the major local sou...

it the first U.S. purchase by a utility of low-carbon power from a commercial-scale, coal-based power plant with carbon capture. The 400-MW TCEP plant is a first-of-its-kind integrated gasification combined cycle (IGCC) poly-generation facility capable of capturing 90 percent of the carbon dioxide (CO 2) it produces. The $2.4-billion plant was a third round selection under DOE's Clean Coal Powe...

Structurally preserved vascular plants have recently been discovered in calcite petrifactions near the town of Shade, Ohio The florule includes representatives of all of the major groups of Carboniferous-age vascular plants, with members of the Calamitales and Marattiales appearing in the highest percentages. The relationships between the Shade coal-ball plants and other coal-ball floras in Nor...

In order to better understand groundwater influx and protection in coal mining extraction works, an in-house water flow apparatus coupled with an industrial rock testing system, known as MTS 815.02, were used to study the effects of grain size mixtures on the compaction and flow properties of disintegrated, or non-cemented, coal samples. From the Reynolds number evaluation of the samples with d...
