The world’s largest natural gas to ethylene glycol demonstration project has another good news about the construction of important equipment. On September 30, Xinjiang Zhongkun New Materials Co., Ltd. (referred to as “Zhongkun New Materials”) 2×600,000 tons /year Natural Gas to Ethylene Glycol Project (Phase I) Thermal Power Project After the mechanical completion, the 1# boiler was successfully ignited for the first time, marking that the Zhongkun Thermal Power Project has completed the set goals and has successfully shifted from the construction stage to the trial production stage.
The Zhongkun Thermal Power Project (Phase I) includes two 320t/h circulating fluidized bed boilers and one 39MW extraction back-pressure steam turbine generator unit and its supporting facilities. Construction will start in November 2022, and the boiler will be installed in February 2023. The installation of the first steel structure began. On March 16th, the large plate beams of the 1# boiler were hoisted. On May 6th, the main factory building was capped. On May 30th, the water pressure test of the 1# boiler was carried out. On June 30th, the outer tube of the chimney was capped. In September The 1# boiler was successfully ignited on the 30th, and it took less than 8 months to successfully ignite the 1# boiler.
As the world’s largest natural gas to ethylene glycol demonstration project, the project has a total investment of 10.8 billion yuan and covers an area of 1,500 acres. It uses natural gas as raw material and adopts the internationally advanced oxidative coupling ethylene glycol production process to build an air separation unit and conversion device, purification separation device, DMO device and ethylene glycol device, as well as supporting public works, forming an annual production capacity of 1.2 million tons of ethylene glycol.
Zhongkun New Materials’ 2×600,000 tons/year natural gas-to-ethylene glycol project is located in the refining-chemical-spinning integrated industrial zone of Korla Petroleum and Petrochemical Industrial Park Production Zone, Bazhou, Xinjiang. The project uses natural gas as raw material and uses Shanghai International Chemical Construction’s natural gas non-catalytic partial conversion (POX) technology to produce syngas. After CO2 is removed from the syngas through the NCMA method of Nanjing Chemical Industry Research Institute, it enters H2/CO cryogenics and PSA pressure swing adsorption. The H2 and CO are separated and used as raw materials for dimethyl oxalate and ethylene glycol devices. CO is fed into the dimethyl oxalate unit to produce DMO, H2 is combined with the dimethyl oxalate produced in the DMO unit to produce ethylene glycol, and ethanol, heavy glycol, light glycol and other by-products are produced. Ethylene glycol and dimethyl oxalate are high chemical technologies. After the project is completed, it will produce 1.2 million tons of ethylene glycol and 55,000 tons of dimethyl carbonate annually. It is of great significance for improving the on-site conversion rate of Xinjiang’s oil and gas resources, accelerating the transformation and upgrading of Bazhou’s petroleum and petrochemical industry, and optimizing the industrial structure of the region and enterprises. The main construction content of the project includes: the main project includes natural gas purification and conversion equipment (cobalt-molybdenum hydrogenation reactor, zinc oxide desulfurization tank, reforming furnace, conversion waste boiler, NCMA absorption tower, regeneration tower, etc.), H2/CO separation device (PSA -H2 device, cold box, etc.), dimethyl oxalate device (NOx generator, DMO reactor, MN regeneration tower, methanol dehydration tower, MN recovery tower, etc.), ethylene glycol device (ethylene glycol synthesis tower, methanol recovery tower, ethylene glycol product tower, etc.); public auxiliary projects include power supply, water supply, drainage, heating, automation control, laboratories, fire protection, office buildings, flares, air separation units, refrigeration stations, etc.; storage and transportation projects include storage, Loading and unloading; environmental protection projects include waste gas, waste water, noise, solid waste treatment projects and environmental risk prevention projects. June 24, East
Hua Science and Technology announced that Donghua Engineering Technology Co., Ltd. and Xinjiang Zhongkun New Materials Co., Ltd. signed the “Zhongkun New Materials 2×600,000 tons/year natural gas to ethylene glycol project (Phase I) construction project general contract contract” 》(hereinafter referred to as “this contract”) will officially come into effect after being signed and sealed by both parties. The total price is 2.901 billion yuan.
