DICOM Image Scrubbing Software Library/Utility

Description: This software is aimed at providing user-friendly, easy-to-use environment for the user to scrub (de-identify/modify) the DICOM header information. Some tools either anonymize or default the values without the user interaction. The user doesn't have the flexibility to edit the header information. One cannot scrub set of images simultaneously (batch scrubbing). This motivated to develop a tool/utility that can scrub a set of images in a single step more efficiently. This document also addresses … more

Methods of Gas Phase Capture of Iodine from Fuel Reprocessing Off-Gas: A Literature Survey

Description: A literature survey was conducted to collect information and summarize the methods available to capture iodine from fuel reprocessing off-gases. Techniques were categorized as either wet scrubbing or solid adsorbent methods, and each method was generally described as it might be used under reprocessing conditions. Decontamination factors are quoted only to give a rough indication of the effectiveness of the method. No attempt is made to identify a preferred capture method at this time, although… more

Advanced Amine Solvent Formulations and Process Integration for Near-Term CO2 Capture Success

Description: This Phase I SBIR project investigated the economic and technical feasibility of advanced amine scrubbing systems for post-combustion CO2 capture at coal-fired power plants. Numerous combinations of advanced solvent formulations and process configurations were screened for energy requirements, and three cases were selected for detailed analysis: a monoethanolamine (MEA) base case and two “advanced” cases: an MEA/Piperazine (PZ) case, and a methyldiethanolamine (MDEA) / PZ case. The MEA/PZ and M… more

Electron Cloud Observations and Cures in Rhic

Description: Since 2001 RHIC has experienced electron cloud effects, which have limited the beam intensity. These include dynamic pressure rises - including pressure instabilities, tune shifts, a reduction of the stability threshold for bunches crossing the transition energy, and possibly incoherent emittance growth. We summarize the main observations in operation and dedicated experiments, as well as countermeasures including baking, NEG coated warm beam pipes, solenoids, bunch patterns, anti-grazing rings… more

BEAM SCRUBBING FOR RHIC POLARIZED PROTON RUN.

Description: One of the intensity limiting factor of RHIC polarized proton beam is the electron cloud induced pressure rise. A beam scrubbing study shows that with a reasonable period of time of running high intensity 112-bunch proton beam, the pressure rise can be reduced, allowing higher beam intensity.

Advanced separation technology for flue gas cleanup. Quarterly technical report No. 5, [April--June 1993]

Description: The objective of this work is to develop a novel system for regenerable SO{sub 2} and NO{sub x} scrubbing of flue gas that focuses on (a) a novel method for regeneration of spent SO{sub 2} scrubbing liquor and (b) novel chemistry for reversible absorption of NO{sub x}. In addition, high efficiency hollow fiber contactors (HFC) are proposed as the devices for scrubbing the SO{sub 2} and NO{sub x} from the flue gas. The system will be designed to remove more than 95% of the SO{sub x} and more tha… more

Enhanced Practical Photosynthetic CO2 Mitigation

Description: This report highlights significant achievements in the Enhanced Practical Photosynthetic CO{sub 2} Mitigation Project for the period ending 09/30/2004. The primary effort of this quarter was focused on mass transfer of carbon dioxide into the water film to study the potential effects on the photosynthetic organisms that depend on the carbon. Testing of the carbon dioxide scrubbing capability (mass transfer capability) of flowing water film appears to be relatively high and largely unaffected by… more

Development of advanced NO{sub x} control concepts for coal-fired utility boilers. Quarterly technical progress report No. 8, July 1, 1992--September 30, 1992

Description: The complete CombiNO{sub x}, process has now been demonstrated at a level that is believed to be representative of a full-scale boiler in terms of mixing capabilities. A summary of the results is displayed in Figure 5-1. While firing Illinois Coal on the Reburn Tower, Advanced Reburning was capable of reducing NO{sub x}, by 83 percent. The injection of methanol oxidized 50--58 percent of the existing NO to N0{sub 2}. Assuming that 85 percent of the newly formed N0{sub 2} can be scrubbed in a li… more

Alternative flue gas treatment technologies for integrated SO{sub 2} and NO{sub x} control

Description: Enactment of the 1990 Clean Air Act Amendments, as well as passage of legislation at the state level has raised the prospect of more stringent nitrogen oxides (NO{sub x}) emission regulations and has fueled research and development efforts on a number technologies for the combined control of sulfur dioxide (SO{sub 2}) and NO{sub x}. The integrated removal of both SO{sub 2} and NO{sub x} in a single system can offer significant advantages over the use of several separate processes, including suc… more

Sorbents for mercury removal from flue gas

Description: A review of the various promoters and sorbents examined for the removal of mercury from flue gas is presented. Commercial sorbent processes are described along with the chemistry of the various sorbent-mercury interactions. Novel sorbents for removing mercury from flue gas are suggested. Since activated carbons are expensive, alternate sorbents and/or improved activated carbons are needed. Because of their lower cost, sorbent development work can focus on base metal oxides and halides. Addition… more

A method for the removal of elemental mercury from a gas stream

Description: A method is provided to remove elemental mercury from a gas stream by reacting the gas stream with an oxidizing solution to convert the elemental mercury to soluble mercury compounds. Other constituents are also oxidized. The gas stream is then passed through a wet scrubber to remove the mercuric compounds and oxidized constituents.

Technical letter report: Submerged bed scrubber sediment resuspension testing for the Hanford Waste Vitrification Plant

Description: During-vitrification operations in the Hanford Waste Vitrification Plant (HWVP), some feed components will be vented from the melter to the melter offgas cleaning equipment. The current HWVP reference process for melter off.-gas treatment includes a submerged bed scrubber (SBS) to provide the first stage of off-gas scrubbing and quenching. During most melter/off-gas test runs at Pacific Northwest Laboratory (PNL) with the Pilot Scale Ceramic Melter (PSCM) and at the West Valley Demonstration Pr… more

Ultralow Concentration Mercury Treatment Using Chemical Reduction and Air Stripping

Description: Field, laboratory and engineering data confirmed the efficacy of chemical reduction and air stripping as an ultralow concentration mercury treatment concept for water containing Hg(II). The simple process consists of dosing the water with low levels of stannous chloride (Sn(II)) to cover the mercury to Hg degrees. This mercury species can easily be removed from the water by air stripping or sparging.

A comparison of wet and dry scrubbing systems for control of metals and dioxin/furan emissions from incinerators

Description: In Europe and the United States, both wet and dry (including semidry) scrubbing systems are being used for control of emissions from all types of waste incinerators. In terms of the effectiveness of controlling particulates and acid gases, both types of scrubbing systems are capable of meeting US Environmental Protection Agency and European Community limits. Two of the more difficult emissions requirements for an incinerator air-pollution-control system to meet are the metals and the dioxin/fur… more
