- Description
- NAICS Code: 541710 The US Environmental Protection Agency (EPA), Office of Research and Development (ORD), intends to negotiate, on a sole source basis, under the authority of FAR 13.106-1(b), with Breen Energy Solutions to perform and validate a definitive kinetic study of mercury oxidation mechanisms, including the effect of flue gas temperature gradients and heterogeneous kinetic mechanisms on the extent of high temperature mercury oxidation at the U.S. EPA's National Risk Management Research Laboratory. The current NAICS code is 541710. Based on the EPA's knowledge of the Technical Support needed for the Statement of Work (SOW) there may be unique capabilities to particular contractors/consultants. The SOW is as follows: STATEMENT OF WORK Enhancement of Mercury Oxidation on a Pilot-Scale Coal Fired Combustor Period of Performance: 12 Months from the date of award Estimated Level of Effort: The level of effort for this project is estimated to be 250 hours. Goal The goal of the proposed project is to perform and validate a kinetic study of mercury oxidation mechanisms, including the effect of flue gas temperature gradients and heterogeneous kinetic mechanisms on the extent of high temperature mercury oxidation. This work provides an important alternative mercury oxidation enhancement technology that maximizes carbon effects and doesn't require the addition of chlorine or bromine compounds either to the flue gas or to activated carbon. This requirement would further the EPA's mission as follows: "The work would serve to explain the variability in mercury emissions often observed and documented under the EPA's Information Collection Request (ICR) and will provide a foundation for the extension of studies now being conducted to reduce mercury emissions from coal-fired boilers." The work would produce a kinetic model of mercury speciation, which would be a valuable national resource as utility and industrial coal-fired boilers implement technology to meet mercury regulations through a wide range of national coal supply. This will fill an important gap in the current understanding of mercury oxidation mechanisms. "Results would be published in a peer-reviewed journal and at trade shows to add to the national knowledge base on mercury and disseminate the results to a wide audience. Approach 1. Areas of interest and parameters to be tested include the following test matrix: " Flue gas starting temperature. " Flue gas temperature gradient across heat exchanger (economizer simulation). " Coal type (sub-bituminous and bituminous). " Coal Cl and mercury content. " Fly ash carbon levels and carbon surface activity. " Continuing experiment planning, test matrix development and on-going data review. " Available kinetic modeling results will provide guidance, definition and a-priori predictions for this matrix. 2. Test runs at NRMRL's combustor " Testing and experimental verification of existing kinetic curves. " Obtain parametric data for: flue gas temperature entering and leaving heat exchanger flue gas temperature rate of change (quenching rate) in heat exchanger fly ash unburned carbon levels Coal rank and chlorine content oxidized mercury entering and leaving heat exchanger. " Define maximum mercury oxidation possible, and limitations to oxidation. 3. Data reduction, reporting and publication of results Task 1: Test Definition/Matrix Development with the Laboratory EPA Laboratory Responsibilities: 1. Laboratory personnel will provide the Contractor with drawings, flue gas flow rates and temperatures, and firing rates for the Multi-Pollutant Control Research Facility (MPCRF). 2. The Laboratory will install flue gas sampling locations at the inlet and outlet of HX 2-b in the convective section of the MPCRF. 3. The Laboratory will install thermocouples for measuring the flue gas temperature going into and out of HX 2-b of the MPCRF. 4. The Laboratory will work with the Contractor to finalize the actual test matrix. Contractor Tasks: 1. The Contractor shall use data provided by the Laboratory to evaluate flue gas cooling rates at the various heat exchangers in the combustor. 2. The Contractor shall specify where to install additional flue gas sampling and temperature measurement capabilities. 3. The Contractor shall work with the Laboratory to finalize the actual test matrix. The test matrix will be combinations of the following parameters, plus any other items identified during Task 1 and capable of being tested/varied. Parametric Variable Conditions to be tested Coal Type Subituminous, bituminous Flue gas quench rate, F/s Max. possible, 2000 F/s, 1000 F/s Flue gas inlet temperature, F 1250, 1150, 1100 Flue gas outlet temperature, F 750, 650, 600 Coal Cl, ppm (by weight, daf basis) As found in coal LOI, wt. % Baseline, +1%, +3% as active surface of C CO spike, ppm 25, 100 Task 2: Perform Experiments at NRMRL Combustor EPA Laboratory Responsibilities: 1. The Laboratory will fire the combustor according to the test matrix defined in Task 1. An EPA technician or on-site contractor will operate the combustor and sampling equipment. 2. Set-up and demonstration of temperature control and flue gas monitoring may require at least one week of firing prior to data collection. It is estimated that one week of subituminous coal firing and one week of bituminous coal firing will be necessary for this test program. NRMRL will provide analyses for each coal to be tested: Proximate analysis Ultimate analysis Higher heating value Coal Hg and Cl content NRMRL will sample the flue gas for each test run: O2, CO, NOx, CO2, SO2 Fly ash unburned carbon Mercury speciation - elemental, oxidized, particulate Contractor Tasks: 1. The contractor shall coordinate test runs and scheduling with NRMRL. 2. The effects of active carbon and flue gas cooling within the 1150-650 F gradient will be emphasized by the contractor when compromise between exact test conditions desired and actual operating capabilities, is required during experimental runs. 3. The contractor shall provide technical support to NRMRL in combustor operation and data collection. Two contractor engineers shall be on-site for this purpose during experimental data collection runs. Task 3: Data Analysis and Presentation of Results EPA Laboratory Responsibilities: 1. NRMRL will provide the contractor with the data enumerated under Task 2. 2. NRMRL will co-author papers for presentation at appropriate industry conferences such as the MEGA symposium. EPA personnel will present the papers where budgets and work schedule permit. Contractor Tasks: 1. The contractor shall integrate results of this test program with kinetic modeling runs for mercury speciation produced by Niksa Energy Associates (NEA). 2. The contractor shall specify any additional kinetic modeling runs needed for comparison to this data set and for validation of the mercury oxidation mechanisms modeled. 3. The contractor shall prepare at least one manuscript for submission to the Mega Symposium or the Air and Waste Management Annual Conference. This shall include reducing the data and submitting the manuscript to the conference organizers. EPA personnel will present the paper(s) where budgets and work schedules permit. In the event EPA personnel are not able to attend the conference, the contractor shall be responsible for presentation of the results at the conference. Task 4: Presentation of Test Results for Conference Paper The contractor shall prepare at least one manuscript for submission to the Mega Symposium or the Air and Waste Management Annual Conference. This shall include reducing the data and submitting the manuscript to the conference. EPA personnel will present the paper(s) where budgets and work schedules permit. In the event EPA personnel are not able to attend the conference, the contractor shall be responsible for presentation of the results at the conference. Task 5: Preparation of Peer Reviewed Journal Article The contractor shall prepare at least one manuscript on the work performed in this study for submission to a peer reviewed journal. This includes preparing the manuscript in accordance with the style used by the selected journal. The journal article shall be cleared for publication by the EPA's technical review system prior to publication. Deliverable Schedule Identify specific deliverables and the timeline for delivery.
