Successful Completion of Heavy-Lift Installation for Shaanxi Jingyi Chemical Project Author/Source: Shaanxi Huajian Date: 2019-07-17 Clicks: 31 The installation of the 155-ton gas-to-gas heat exchanger equipment for Shaanxi Jingyi Chemical’s synthesis unit marks the successful completion of the company’s heavy-lift installation work on this project. It is reported that this project is a key project in Shaanxi Province, with an estimated investment of around 4.6 billion yuan, and it is primarily focused on the production of high-value-added chemical products derived from aromatics. Upon completion, the project will become the largest coal-based aromatic compounds manufacturing facility in the country. Shaanxi Jingyi Chemical Co., Ltd.’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 primarily produces 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.
