Chemical Looping Combustion Kinetics (open access)

Chemical Looping Combustion Kinetics

One of the most promising methods of capturing CO{sub 2} emitted by coal-fired power plants for subsequent sequestration is chemical looping combustion (CLC). A powdered metal oxide such as NiO transfers oxygen directly to a fuel in a fuel reactor at high temperatures with no air present. Heat, water, and CO{sub 2} are released, and after H{sub 2}O condensation the CO{sub 2} (undiluted by N{sub 2}) is ready for sequestration, whereas the nickel metal is ready for reoxidation in the air reactor. In principle, these processes can be repeated endlessly with the original nickel metal/nickel oxide participating in a loop that admits fuel and rejects ash, heat, and water. Our project accumulated kinetic rate data at high temperatures and elevated pressures for the metal oxide reduction step and for the metal reoxidation step. These data will be used in computational modeling of CLC on the laboratory scale and presumably later on the plant scale. The oxygen carrier on which the research at Utah is focused is CuO/Cu{sub 2}O rather than nickel oxide because the copper system lends itself to use with solid fuels in an alternative to CLC called 'chemical looping with oxygen uncoupling' (CLOU).

Oral History Interview with John G. Solis, March 31, 2009

The National Museum of the Pacific War presents an oral interview with John G. Solis of Irving, Texas. He discusses enlisting in the U.S. Navy on September 17, 1942, and was sent to the Naval Air Station in Corpus Christi, Texas for bootcamp. In bootcamp Mr. Solis talks about learning to shoot rifles by shooting clay pigeons and presentations held to teach how to identify enemy aircraft. While learning to fly, Mr. Solis was assigned to Bombing Squadron 1. In 1944 Mr. Solis ended up with the Torpedo Squadron 100 flying torpedo planes in Oahu, Hawaii. His squadron never saw combat, but he did witness U.S. ships getting destroyed by Kamikaze planes during the Okinawa invasion. He helped in some Naval strikes in Japan from March to June of 1945 before returning to the states for leave. Mr. Solis was still at home on leave when the war officially ended, and he was discharged on September 14th of 1948 due to signing up for a 6-year contract instead of the normal 4-year one.

Troubled Asset Relief Program: Status of Efforts to Address Transparency and Accountability Issues

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses our work on the Troubled Asset Relief Program (TARP), under which the Department of the Treasury (Treasury) has the authority to purchase and insure up to $700 billion in troubled assets held by financial institutions through its Office of Financial Stability (OFS). As Congress may know, Treasury was granted this authority in response to the financial crisis that has threatened the stability of the U.S. banking system and the solvency of numerous financial institutions. The Emergency Economic Stabilization Act (the act) that authorized TARP on October 3, 2008, requires GAO to report at least every 60 days on the findings resulting from our oversight of the actions taken under the program. We are also responsible for auditing TARP's annual financial statements and for producing special reports on any issues that emerge from our oversight. To carry out these oversight responsibilities, we have assembled interdisciplinary teams with a wide range of technical skills, including financial market and public policy analysts, accountants, lawyers, and economists who represent combined resources from across GAO.

Global War on Terrorism: Reported Obligations for the Department of Defense

Correspondence issued by the Government Accountability Office with an abstract that begins "Since 2001, Congress has provided the Department of Defense (DOD) with about $808 billion in supplemental and annual appropriations, as of March 2009, primarily for military operations in support of the Global War on Terrorism (GWOT). DOD's reported annual obligations for GWOT have shown a steady increase from about $0.2 billion in fiscal year 2001 to about $162.4 billion in fiscal year 2008. For fiscal year 2009, Congress provided DOD with about $65.9 billion in supplemental appropriations for GWOT as of March 2009 and the President plans on requesting an additional $75.5 billion in supplemental appropriations for GWOT for the remainder of the fiscal year. A total of $31.0 billion has been obligated in the first quarter of fiscal year 2009 through December 2008. The United States' commitments to GWOT will likely involve the continued investment of significant resources, requiring decision makers to consider difficult trade-offs as the nation faces an increasing long-range fiscal challenge. The magnitude of future costs will depend on several direct and indirect cost variables and, in some cases, decisions that have not yet been made. DOD's future costs will likely be affected by …

JV Task 126 - Mercury Control Technologies for Electric Utilities Burning Bituminous Coal (open access)

JV Task 126 - Mercury Control Technologies for Electric Utilities Burning Bituminous Coal

The EERC developed an applied research consortium project to test cost-effective mercury (Hg) control technologies for utilities burning bituminous coals. The project goal was to test innovative Hg control technologies that have the potential to reduce Hg emissions from bituminous coal-fired power plants by {ge}90% at costs of one-half to three-quarters of current estimates for activated carbon injection (ACI). Hg control technology evaluations were performed using the EERC's combustion test facility (CTF). The CTF was fired on pulverized bituminous coals at 550,000 Btu/hr (580 MJ/hr). The CTF was configured with the following air pollution control devices (APCDs): selective catalytic reduction (SCR) unit, electrostatic precipitator (ESP), and wet flue gas desulfurization system (WFDS). The Hg control technologies investigated as part of this project included ACI (three Norit Americas, Inc., and eleven Envergex sorbents), elemental mercury (Hg{sup 0}) oxidation catalysts (i.e., the noble metals in Hitachi Zosen, Cormetech, and Hitachi SCR catalysts), sorbent enhancement additives (SEAs) (a proprietary EERC additive, trona, and limestone), and blending with a Powder River Basin (PRB) subbituminous coal. These Hg control technologies were evaluated separately, and many were also tested in combination.

Human Subjects Research: Undercover Tests Show the Institutional Review Board System Is Vulnerable to Unethical Manipulation

Testimony issued by the Government Accountability Office with an abstract that begins "Millions of Americans enroll in clinical studies of experimental drugs and medical devices each year. Many of these studies are meant to demonstrate that products are safe and effective. The Department of Health and Human Services' (HHS) Office for Human Research Protections (OHRP) and the Food and Drug Administration (FDA) are responsible for overseeing aspects of a system of independent institutional review boards (IRB). IRBs review and monitor human subjects research, with the intended purpose of protecting the rights and welfare of the research subjects. GAO investigated three key aspects of the IRB system: (1) the process for establishing an IRB, (2) the process through which researchers wishing to apply for federal funding assure HHS their human subjects research activities follow ethical principles and federal regulations, and (3) the process that medical research companies follow to get approval for conducting research on human subjects. GAO investigated these three aspects of the IRB system by creating two fictitious companies (one IRB and one medical device company), phony company officials, counterfeit documents, and a fictitious medical device."

Oral History Interview with Leo Itz, March 26, 2009

The National Museum of the Pacific War presents an oral interview with Leo Itz. Itz was given a one-year exemption in order to help his father on the farm before he was drafted into the Army in March 1945. He was trained in demolitions at Fort Lewis and sent to Luzon to join the 395th Infantry Regiment. Before shipping out to the Philippines, he was assigned to work at Del Monte Foods in California, due to the labor shortage. During his voyage overseas, the war ended. Itz was tasked with guarding an ammunition dump outside of Clark Field. Armed only with an unloaded rifle, he came under fire when Japanese holdouts were raiding the dump. He returned safely to his bunk, only to discover a putrid smell. In the ground beneath him was a shallow grave. In August 1945, Itz was granted a dependency discharge upon learning that his father had suffered a heart attack. He returned to the States in December.

Climate Change: Observations on Federal Efforts to Adapt to a Changing Climate

Testimony issued by the Government Accountability Office with an abstract that begins "Changes in the climate attributable to increased concentrations of greenhouse gases may have significant environmental and economic impacts in the United States. For example, climate change could threaten coastal areas with rising sea levels, alter agricultural productivity, and increase the intensity and frequency of floods and storms. Federal, state, and local agencies are tasked with a wide array of responsibilities that will be affected by a changing climate, such as managing natural resources. Furthermore, climate change could increase the cost of federal programs, such as crop and flood insurance, and place new stresses on infrastructure. Greenhouse gases already in the atmosphere will continue altering the climate system into the future regardless of emissions control efforts. Therefore, adaptation--defined as adjustments to natural or human systems in response to actual or expected climate change--is an important part of the response to climate change. Today's testimony summarizes GAO's prior and ongoing work examining (1) actions that federal, state, local, and international authorities are taking to adapt to a changing climate, (2) the challenges that federal, state, and local officials face in their efforts to adapt, and (3) actions that the Congress …

Department of Labor: Wage and Hour Division's Complaint Intake and Investigative Processes Leave Low Wage Workers Vulnerable To Wage Theft

Testimony issued by the Government Accountability Office with an abstract that begins "The mission of the Department of Labor's Wage and Hour Division (WHD) includes enforcing provisions of the Fair Labor Standards Act, which is designed to ensure that millions of workers are paid the federal minimum wage and overtime. Conducting investigations based on worker complaints is WHD's priority. According to WHD, investigations range from comprehensive investigations to conciliations, which consist primarily of phone calls to a complainant's employer. In July 2008, GAO testified on 15 case studies where WHD failed to investigate complaints. This testimony highlights the findings of a follow-up investigation performed at the Committee's request. Specifically, GAO was asked to (1) test WHD's complaint intake process in an undercover capacity, (2) provide additional case study examples of inadequate WHD responses to complaints, and (3) assess the effectiveness of WHD's complaint intake process, conciliations, and other investigative tools. To test WHD's complaint intake process, GAO posed as complainants and employers in 10 different scenarios. To provide case study examples and assess effectiveness of investigations, GAO used data mining and statistical sampling of closed case data for fiscal year 2007. GAO plans to issue a follow-up report with recommendations …

HUBZone Program: Fraud and Abuse Identified in Four Metropolitan Areas

Testimony issued by the Government Accountability Office with an abstract that begins "Created in 1997, the HUBZone program provides federal contracting assistance to small businesses in economically distressed communities, or HUBZone areas, with the intent of stimulating economic development in those areas. On July 17, 2008, we testified before Congress that SBA's lack of controls over the HUBZone program exposed the government to fraud and abuse and that SBA's mechanisms to certify and monitor HUBZone firms provide limited assurance that only eligible firms participate in the program. In our testimony, we identified 10 firms from the Washington, D.C., metropolitan area that were participating in the HUBZone program even though they clearly did not meet eligibility requirements. Of the 10 firms, 6 did not meet both principal office and employee residency requirements while 4 met the principal office requirement but significantly failed the employee residency requirement. We reported in our July 2008 testimony that federal agencies had obligated a total of nearly $26 million in HUBZone contract obligations to these 10 firms since 2006. After the hearing, Congress requested that we perform a follow-on investigation. We describe the results of this investigation and further background about the HUBZone program in a …
