On the morning of July 1, 2020, the ethylene glycol unit of Hami Guanghui Ethylene Glycol Project began to hoist the first main pipeline, marking the start of pipeline installation, the largest single project of the project.
The total welding volume of pipelines in Hami Guanghui Ethylene Glycol Project is 1.3 million din. The pipelines of this project generally have large diameters, tight construction schedules, and compact sites. In order to ensure that the pipelines The construction was completed on schedule. The project team did a lot of preparation and planning work in the early stage: on the one hand, they prepared enough pipeline prefabrication sites, and on the other hand, they kept abreast of the civil construction progress to ensure that the pipeline work surface was launched in time. At present, the project’s DMO refining, ethylene glycol synthesis, conversion and heat recovery frame steel structure has been basically installed, and the pipeline installation conditions are met; the ground pipe and civil foundation are in the final stage; equipment is gradually arriving at the project site, of which 42 units have arrived. 19 units have been installed.
Since the Hami Guanghui ethylene glycol project site has fully resumed work and production, the project has received great attention from local government departments, Guanghui Group and company leaders . Leaders such as the Secretary of the Hami Municipal Party Committee and the Vice President of Guanghui Group visited the project site to inspect and guide the resumption of work and production.
The Hami Guanghui ethylene glycol project is currently in the final stage of civil construction, and the civil construction and equipment and pipeline installation work are being carried out in an orderly manner.
On September 9, 2019, Guanghui Energy’s comprehensive utilization of coal gas shortage project with an annual output of 400,000 tons of ethylene glycol started construction. The project relies on Xinjiang, a subsidiary of Guanghui Energy Holdings The 10 million tons/year coal grading and upgrading comprehensive utilization project invested and constructed by Guanghui Coal Clean Refining Co., Ltd. uses by-product waste gas as raw material and uses a series of technologies such as conversion, transformation, adsorption, and separation to produce high-end chemical ethylene dioxide. alcohol.
China Wuhuan Engineering Company, the general contractor of the project, signed a cooperation agreement with Peking University Pioneer Company. Peking University Pioneer will design and build the raw gas pressure swing adsorption purification 45720Nm3/h The carbon monoxide device produces carbon monoxide products with a purity of more than 98.5%, which will all be used for ethylene glycol production. Data shows that this PSA-CO device is also the largest pressure swing adsorption CO purification device in the world so far.
The construction site of Guanghui Ethylene Glycol Project is located in Naomao Lake Industrial Park, Yiwu County, Hami City, Xinjiang, with a total investment of 3.56 billion yuan. The project uses the third-generation technology of “WHB synthesis gas to polyester-grade ethylene glycol” jointly developed by China Wuhuan Huashuo Technology Co., Ltd. and Hebi BMW (Group) Co., Ltd., through conversion, transformation, low-temperature methanol washing, Through a series of processes such as PSA adsorption and separation, the high-value syngas components H2 and CO in raw coal gas are extracted, and high-end chemical products – polyester grade ethylene glycol are produced through carbonylation, hydrogenation, and refining technologies.
Compared with the coal-to-ethylene glycol project, using raw coal gas to produce ethylene glycol can save more than 30% of project construction investment, significantly reduce the production cost of ethylene glycol products, and improve The overall profitability of the project not only conforms to the new green development concept, but also plays a very positive role in promoting energy conservation and emission reduction and promoting ecological and environmental protection. </p
