Successful Ignition of Boiler No. 2 in Shaanxi Jingyi Chemical’s 500,000-ton Coal Tar Deep Processing Project Author/Source: Northwest Electric Power First Engineering Company Date: November 28, 2019 Clicks: 42 At 22:22 on November 25, Boiler No. 2 of Shaanxi Jingyi Chemical’s coal tar deep processing and multi-product integrated utilization project, constructed by Northwest Electric Power First Company, was successfully ignited on the first attempt. It is reported that the project is located in the Jinjie Industrial Park in Shenmu City, Shaanxi Province. For this project, a total of 3 high-temperature and high-pressure circulating fluidized bed boilers with a steam flow rate of 240 tons per hour, operating at 9.81 MPa and 540°C, manufactured by Wuxi Huaguang Boiler Co., Ltd., were installed, along with 2 high-pressure double-extraction direct air-cooled condensing steam turbines of the CCZK50-8.83/4.3/1.3 type, produced by Nanjing Turbine Factory. The pipeline system within the power station site was designed by China Coal Xi’an Design and Engineering Co., Ltd. The piping system uses a master pipe layout. Upon completion of this project, it will not only meet the heat and steam needs of the chemical production area within the factory, but also satisfy the demands for electricity development in the region. It will significantly alleviate local employment pressures. Additionally, it will improve centralized heating conditions, which is important for enhancing energy efficiency, achieving increased production while reducing pollution, and greatly improving the regional environmental quality. It will also play a vital role in promoting the development of the circular economy, as well as economic and social progress and urban development in this area. The project mainly includes a 550,000-ton/year coal tar pretreatment unit, a 500,000-ton/year coal tar fluidized-bed hydrocracking unit, a 450,000-ton/year coal tar fixed-bed hydrocracking unit, a 400,000-ton/year naphtha continuous reforming unit, a 170,000-ton/year aromatic extraction unit, a 50,000 cubic meters per hour coal-to-hydrogen unit, a 50,000 cubic meters per hour air separation unit, and a 100,000-ton/year methanol synthesis unit. It also includes related supporting facilities such as hydrogen purification (PSA) units, sulfur recovery units, phenol-amine recovery units, storage and transportation systems, as well as other auxiliary and environmental protection systems.
