Progress on the Construction of Xinjiang Zhongkun New Materials Co., Ltd.’s 2×600,000 tons/year Ethylene Glycol Production Project from Natural Gas / Author/Source: Gasification World / Date: 2022-11-30 / Clicks: 22 On November 28, the pouring of the large-volume concrete for the floor of the 1124 comprehensive pump station in the first phase of Xinjiang Zhongkun New Materials Co., Ltd.’s 2×600,000 tons/year ethylene glycol production project from natural gas, which is under the general contract of Donghua Engineering Technology Co., Ltd. (referred to as “Donghua Technology”), was successfully completed. This achievement accelerated the progress of the project as a whole and laid a solid foundation for achieving the target of completing the construction on schedule. The bottom slab of the pool in the integrated pumping station is approximately 56 meters long and 52 meters wide, with a thickness of 0.5 meters; the bottom slab of the water intake pool has a thickness of 0.6 meters. The total volume of concrete required for pouring is around 1,700 cubic meters. As the contractor, Donghua Technology is responsible for the engineering design within the scope of this project, the procurement of certain equipment and materials, construction work, as well as providing technical services from the completion of the machinery until performance testing (final performance assessment) and the completion acceptance of the contracted facilities ； The contract price consists of a fixed amount and a time bonus, totaling 2.901 billion yuan. The target date for the completion of the machinery installation is September 30, 2023, while the date for commissioning the plant is December 31, 2023. Project Overview: The 2×600,000 tons/year natural gas-to-ethylene glycol project of Zhongkun Chemical is located in the petrochemical and textile integration industrial zone within the Korla Petroleum and Petrochemical Industrial Park in Bortala Prefecture, Xinjiang. The project uses natural gas as raw material and employs Shanghai International Construction’s non-catalytic partial oxidation (POX) technology to produce syngas. After CO2 is removed from the syngas using the NCMA method at the Nanjing Chemical Research Institute, it undergoes deep cooling and PSA pressure swing adsorption to separate H2 and CO, which are then used as raw materials for the dimethyl oxalate and ethylene glycol production facilities. CO is used in the dimethyl oxalate plant to produce DMO, while H2 and the dimethyl oxalate produced in that plant are used to manufacture ethylene glycol; by-products such as ethanol, heavy diols, and light diols are also generated. Ethylene glycol and dimethyl oxalate are high-tech chemicals. Upon completion, the project will produce 1.2 million tons of ethylene glycol and 55,000 tons of dimethyl carbonate per year. It plays a significant role in increasing the local conversion rate of oil and gas resources in Xinjiang, accelerating the transformation and upgrading of the petroleum and petrochemical industries in Bayingolin Mongol Autonomous Prefecture, and optimizing the industrial structure of both the region and its enterprises. The main construction components of the project include: the core facilities, which consist of natural gas purification and conversion units (cobalt-molybdenum hydrogenation reactors, zinc oxide desulfurization tanks, conversion furnaces, conversion waste boilers, NCMA absorption towers, regeneration towers, etc.), H2/CO separation units (PSA-H2 units, cryogenic tanks, etc.), dimethyl oxalate production units (NOx generators, DMO reactors, MN regeneration towers, methanol dehydration towers, and MN recovery towers, etc.), and ethylene glycol production units (ethylene glycol synthesis towers, methanol recovery towers, ethylene glycol product towers, etc.) ； Auxiliary engineering includes power supply, water supply, drainage, heating, automatic control, laboratories, fire protection, office buildings, flares, air separation units, refrigeration stations, etc ； Storage and transportation engineering includes storage, loading, and unloading ； Environmental protection engineering includes projects for treating waste gas, wastewater, noise, and solid waste, as well as projects for preventing environmental risks. The total land area of the project is 931,700 square meters, with a total investment of 886,997.13 million yuan; of this amount, 232,300 million yuan is allocated to environmental protection measures, accounting for 2.62% of the total investment. On June 24, Donghua Technology issued a statement stating that the \"General Contract for the Construction of the Zhongkun New Materials 2×600,000 tons/year Natural Gas-to-Ethylene Glycol Project (Phase I)\\" (hereinafter referred to as \"this Contract\") signed between Donghua Engineering Technology Co., Ltd. and Xinjiang Zhongkun New Materials Co., Ltd. came into effect officially after being signed and sealed by both parties. The total price is 2.901 billion yuan. On September 23, the groundbreaking ceremony for Section 3 of the main plant of Xinjiang Zhongkun New Materials Co., Ltd.’s 2×600,000 tons per year natural gas-to-ethylene glycol project was successfully held at the project site.
