Carbon dioxide capture from coal-fired power plants : a real potions analysis
Investments in three coal-fired power generation technologies are valued using the "real options" valuation methodology in an uncertain carbon dioxide (CO2) price environment. The technologies evaluated are pulverized coal (PC), integrated coal gasification combined cycle (baseline IGCC), and IGCC …

Remediation Strategies for Mercury Contaminated Lakes and Reservoirs Within the State of California
… due to lack of non-invasive mercury accumulating plants. Aqueous capping is a viable method, but only if the lake or reservoir is small in size. HOS is the least problematic remediation method investigated in this paper. HOS controls and prevents mercury from being methylated and entering the food …

Continuum Damage Mechanics (CDM) modelling of dislocation creep in 9-12% Cr creep resistant steels
… immense pressure on how quickly and efficiently power is produced. Being the most prevalent source of electricity generation, coal fired power plants have been subject to increasing scrutiny and study in an effort to improve the efficiency at which they operate. Hence, coal fired power plants are …
