资料简介
美国能源部（DOE）编制了本环境评估（EA），以评估向Viresco Energy，LLC（Viresco）提供资金援助，以建设和运营以煤和生物质为燃料的中试工厂的潜在影响。位于犹他州卡纳布。该工厂将位于犹他州学校和机构信托土地管理局出租给Viresco的土地上。该试验工厂将占地10英亩，占地约1.5英亩，位于犹他州卡纳布市区以南约2.5英里处。 《 2010财年能源与水开发及相关机构拨款法》（第111-85号公共法）包括由当时的犹他州参议员Bennett赞助的“犹他州煤和生物质燃料试点工厂”拨款250万美元。能源部将向Viresco提供财务支持，以支持其设计，建造和测试中试规模的蒸汽加氢气化设施。根据成本分摊协议，美国能源部将提供2,404,000美元（约占研发项目总成本的80％），Viresco将出资剩余的601,000美元。试点工厂将由Viresco建造，拥有和运营。 Viresco负责获得项目所需的许可证和其他授权；美国能源部对该项目或其运营没有监管权限。根据合作协议，Viresco将运营试点工厂，并收集一系列试验运行的数据，这些试验在几个月内共运行30天；在DOE的财务援助终止后，Viresco计划寻求更多资金以继续运营。 Viresco拟议项目的目的是对蒸汽加氢气化反应（SHR）过程进行中试评估。试点工厂将是一个小型工厂，旨在评估使用蒸汽加氢气化将煤炭和生物质（例如农业或木材加工废料）转化为合成气（合成气）并最终转化为清洁燃料（例如天然天然气）的技术可行性。汽油，无硫费托柴油机，喷气燃料，二甲醚和甲烷。该SHR气化技术在试点规模的成功运行将提供开发该工艺商业化途径所需的工程信息。该项目支持美国能源部以有效和环保的方式开发和使用国内煤炭和可再生资源的目标。这项技术使用了先进的气化工艺并产生清洁燃料。向煤原料中添加生物质还可以减少温室气体净排放量。 EA发现，Viresco提出的项目最显着的潜在变化将发生在以下领域：土地使用，美学，空气质量，固体和危险废物，公用事业和社会经济学。在分析这些潜在变化时未发现重大的环境影响
The U.S. Department of Energy (DOE) prepared this Environmental Assessment (EA) to evaluate the potential impacts of providing financial assistance to Viresco Energy, LLC, (Viresco) for its construction and operation of a Coal and Biomass Fueled Pilot Plant, that would be located in Kanab, Utah. The plant would be located on land leased to Viresco by the Utah School and Institutional Trust Lands Administration. The Pilot Plant would occupy approximately 1.5 acres of a 10-acre site located approximately 2.5 miles south of the downtown area of Kanab, Utah. The Fiscal Year 2010 Appropriations Act for Energy & Water Development and Related Agencies (Public Law 111-85) included a $2,500,000 earmark sponsored by then Senator Bennett of Utah for the “Utah Coal and Biomass Fueled Pilot Plant.” In accordance with the earmark, DOE would provide financial assistance to Viresco to support its design, construction, and testing of a pilot-scale steam hydrogasification facility. Under a costsharing agreement, DOE would provide $2,404,000 (approximately 80 percent of the total cost of the research and development project) and Viresco would contribute the remaining $601,000. The Pilot Plant would be constructed, owned, and operated by Viresco. Viresco is responsible for obtaining the permits and other authorizations needed for the project; DOE would have no regulatory authority over the project or its operation. Under the cooperative agreement, Viresco would operate the Pilot Plant and collect data for a series of test runs totaling 30 days of operation over a period of months; after DOE’s financial assistance ends, Viresco plans to seek additional funding for continued operations. The objective of Viresco’s proposed project is to conduct a pilot-scale evaluation of the Steam Hydrogasification Reaction (SHR) process. The Pilot Plant would be a small-scale facility designed to evaluate the technical feasibility of using steam hydrogasification to convert coal and biomass (such as agricultural or wood processing waste) into synthesis gas (syngas), and ultimately into clean fuels such as substitute natural gas, sulfur-free Fischer-Tropsch diesel, jet fuel, dimethyl ether, and methane. The successful operation of this SHR gasification technology at a pilot scale would provide engineering information needed to develop a commercialization pathway for this process. This project supports DOE’s goal of developing and using domestic coal and renewable resources in an efficient and environmentally acceptable manner. This technology uses an advanced gasification process and produces clean fuels. The addition of biomass to the coal feedstock also reduces net greenhouse gas (GHG) emissions. The EA found that the most notable potential changes from Viresco’s proposed project would occur in the following areas: land use, aesthetics, air quality, solid and hazardous wastes, utilities, and socioeconomics. No significant environmental effects were identified in analyzing these potential changes
