Installation of Methanol Synthesis Tower at Shaanxi Jingyi Chemical Industry – Author/Source: Compiled and published by the Nitrogen Fertilizer and Methanol Technology Network of Shaanxi Jingyi Chemical Industry. Date: May 13, 2019. Clicks: 9. On May 8th, the methanol synthesis tower, a key piece of equipment in Shaanxi Jingyi Chemical Industry’s hydrogen production facility, was installed, marking another significant advancement in the company’s project installation efforts. The methanol synthesis tower in the hydrogen production facility is a vertical shell-and-tube type unit, classified as a Class III pressure vessel. It is the core equipment for methanol production, designed by Hualu Engineering Technology Co., Ltd. and manufactured by Xi’an Nuclear Equipment Co., Ltd. The synthesis tower has a diameter of 3.8 meters, a height of 13.493 meters, and a net weight of 332 tons. On April 20, 2019, the synthesis tower was delivered to the company’s project site. To ensure the success of this lifting operation, Shaanxi Huahe Equipment Lifting and Transportation Company, together with the company’s hydrogen production project team, the construction party, and the supervision unit, conducted preliminary research and formulation of technical plans to guarantee that all aspects such as construction preparation, plan development, site preparation, crane positioning, and trial lifts were carried out flawlessly. After completing the technical briefings and trial lifting operations, at 16:50 on May 8, the synthesis tower began to be lifted slowly, and the lifting was completed successfully at 21:30. The lifting and installation of the synthesis tower have created favorable conditions for the subsequent installation of process piping in the hydrogen production center. Project Overview: The deep processing and multi-product integrated utilization project of coal tar carried out by Shaanxi Jingyi Chemical Co., Ltd. is located in the Jinjie Industrial Park in Shenmu City, covering an area of about 1,200 mu. With a total investment of 4.6 billion yuan, it is a new type of high-end fine chemical demonstration project that receives key support from the Yulin Municipal Party Committee and government. It is expected to be completed and ready for trial operation by the end of October 2019. Upon completion of the project, Shaanxi Jingyi Chemical Company will become the first and largest coal-based aromatic compounds manufacturer in China. 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.
