On the morning of May 24, the commissioning command team of Shaanxi Jingyi Chemical Co., Ltd. held a special meeting to focus on the commissioning of the chemical plant, establish specific goals for this task, and issue a call to action, thus launching a full-scale effort to carry out the feeding and commissioning process of the chemical plant. At the meeting, the company’s test drive office, hydrogen production center, oil products center, storage and transportation center, power center, administrative and logistics team, safety, health, and environment team, equipment maintenance team, instrumentation specialist team, electrical engineering specialist team, and human resources department each presented reports on their work. It focused on reporting on the overall commissioning plan, progress of commissioning, production preparations, and utility systems, as well as the completion status of individual unit tests, airtightness tests, catalyst loading, water circulation tests, and the next steps in the commissioning process ； Supporting conditions such as technical services, preparation of necessary supplies, handling of licensing procedures, and issuance of various permits. At the same time, suggestions and requirements for coordinated solutions were put forward regarding the problems identified during the testing process, as well as the factors that hinder the device’s trial operation. Shaanxi Jingyi Chemical’s 500,000 tons per year project for the deep processing and integrated utilization of coal tar involves the use of advanced technologies with independent intellectual property rights, developed specifically for the characteristics of coal tar. The core technology consists of a combination of boiling-bed hydrogenation for quality improvement of coal tar across all fractions, along with fixed-bed hydrocracking; using medium- and low-temperature coal tar as raw material, this process is used to produce high-value aromatic chemical products. The project covers an area of about 1,200 mu, with an estimated investment of around 4.6 billion yuan. Construction of the project officially began in August 2017, and it is now in the final stages of design, civil works and safety preparations, as well as equipment installation. Completion and commissioning are expected by the end of October 2019. The projects mainly include: 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, a 100,000-ton/year methanol synthesis unit, as well as related supporting facilities such as hydrogen purification (PSA) units, sulfur recovery units, phenol-amine recovery units, storage and transportation systems, and other auxiliary and environmental protection systems.
