Shaanxi Jingyi Chemical’s 500,000-ton coal tar deep processing project is set to resume operations. Author/Source: Yueneng News, Date: 2020-02-20, Clicks: 7. During this special period when the whole nation is working together to combat COVID-19, Shaanxi Jingyi Chemical Co., Ltd. has managed to balance epidemic prevention and control with project construction and production activities, achieving certain results in this regard. During this period, the company successfully completed the maintenance work on Boiler No. 1 in the power station, which provided a solid guarantee for the long-term safe and stable operation of the facility in the future, and laid a firm foundation for the resumption of production and operations by the enterprise. Since its successful first ignition on August 31, 2019, Boiler No. 1 in the company’s power plant has been in continuous operation for 2,902 hours. Based on the requirements of the power grid load and the operating condition of the equipment, the company conducted a thorough analysis to determine the optimal time for maintenance, and decided to shut down Boiler No. 1 for maintenance on February 7. The main tasks will be to inspect wear on the heat exchange surfaces and address any issues with the equipment; the initial plan is for the maintenance to last 10 days. At 17:40 on February 7, Unit 1 boiler was shut down; at 08:00 on February 9, the maintenance work on Unit 1 boiler commenced in full swing, and a tough battle for its repair got under way promptly. Through the joint efforts of all those involved in the inspection, the maintenance work on Boiler No. 1 was completed one day ahead of schedule on February 18, allowing for the commencement of the preparatory tasks prior to restarting the boiler. 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.
