4.6 billion yuan invested; Unit 1 of Shaanxi Jingyi Chemical’s coal tar deep processing project connected to the grid successfully. Author/Source: Coal Tar Deep Processing and Hydrogenation Technology Collaboration Group. Date: 2019-11-06. Clicks: 116. At 1:10 a.m. on November 5, Unit 1 of the Shaanxi Jingyi Chemical project was successfully connected to the grid for the first time. After the complete startup of Unit 1, the boiler combustion was stable, the main steam parameters met the requirements, and the turbine speed rose to 3000 revolutions per minute. With the protective systems necessary for grid connection activated, the unit’s voltage was successfully synchronized with the grid. At present, the auxiliary equipment of Unit 1, such as the turbine and generator, is operating normally; all parameter values are within acceptable ranges, and all systems are running stably. The unit has now entered the phase of load-testing. Shaanxi Jingyi Chemical Co., Ltd.’s project for the deep processing of coal tar and integrated multi-product production is currently the first large-scale coal-based aromatic hydrocarbon production line in China. It enables a comprehensive and systematic utilization of coal at different quality levels, representing a new industrial approach to the conversion and use of coal. The total investment in the project is 4.6 billion yuan. Once it is operational, it is expected to generate an annual sales revenue of around 4.5 billion yuan, with tax payments of over 600 million yuan. The project will also create employment for more than 1,000 people, offering significant economic and social benefits. The project is located in the Jinjie Industrial Park in Shenmu City, Shaanxi Province. The scale of construction includes a power station comprising 3×240 t/h high-temperature and high-pressure mixed combustion circulating fluidized bed boilers, 2×50 megawatt high-temperature and high-pressure directly air-cooled double-condensing steam turbines, 2×60 megawatt air-cooled generators, as well as civil engineering and installation work for other associated auxiliary systems. 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.
