The deep processing project of coal tar at Shaanxi Jingyi Chemical is expected to start trial production with the introduction of materials by the end of June. Author/Source: Business Society; Date: 2020-04-15; Clicks: 27. Since resuming full operations in late March, Shaanxi Jingyi Chemical Co., Ltd. has continued to strengthen epidemic prevention and control measures while making every effort to complete the construction of the project for the comprehensive utilization of coal tar through deep processing on a scale of 500,000 tons per year. The company has accelerated the testing of the production facilities, thus entering a intensive phase of work that lays a solid foundation for starting trial production by the end of June. At present, the company has over 3,000 workers on the project sites. By optimizing the management approach in line with the construction plan, strengthening incentive measures, and continuously investing in equipment and tools, they work overtime to carry out their tasks. 96% of the work has been completed: the civil construction is essentially finished, and the equipment installation is nearly complete. The hydrogen production heat recovery unit, the hydrogen production PSA unit, the oil pretreatment unit, and the oil PSA unit are ready for commissioning. All compressors, except those in the refrigeration station, are ready for individual testing. Regarding equipment commissioning, the company’s production system exerts additional pressure by carrying out daily checks based on the \"three inspections and four determinations\" framework, and holding meetings with the construction team every night to ensure that construction efforts are coordinated effectively and progress smoothly. At present, pipeline purging, pressure testing, flushing, inspection of equipment internals, and unit commissioning are all progressing in an orderly manner as planned, with significant progress having been made in the commissioning of large-scale units and pipeline purging. Of the 56 public external pipeline networks, 49 have been purged and flushed and are ready for operation ； All pipes within the plant area that meet the purging conditions have been purged. Regarding individual unit testing, 12 out of the 28 reciprocating compressors have already undergone testing, while the remaining 16 are scheduled to be tested by April 20. To ensure the smooth and orderly progress of all tasks, the company holds regular meetings of the commissioning command team, project engineering meetings, production scheduling meetings, and unit commissioning coordination meetings. It stays focused on the set objectives, adopts a problem-oriented approach, uses commissioning to drive completion of projects and vice versa, further refines the commissioning and testing plans for various units as well as the catalyst loading plan, and arranges for the arrival of the startup team and expert group at the site, thereby making every effort to advance project construction and unit commissioning activities. By the end of April, all civil engineering works are expected to be completed, and utility systems such as the fire protection water system, finished product storage areas, and external utility pipelines will all be put into operation. Multiple units, including air separation, purification, methanol synthesis, methanol distillation, oil pretreatment, and PSA, will complete their construction phases. By then, individual unit tests will gradually give way to system-wide integrated tests. It is reported that the coal tar deep processing and multi-product integrated utilization project of Shaanxi Jingyi Chemical Co., Ltd. is currently the first large-scale coal-based aromatic hydrocarbon production line in China. It achieves comprehensive and systematic utilization of coal on a differentiated basis, representing a new industrialized approach to coal conversion and utilization. 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 direct 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.
