    Recently, China's independent research and development of a single set of the largest synthetic gas glycol technology industrial equipment driving success, and smooth operation for nearly 2 months, the excellent product rate of 100%. The device takes the purification gas of low temperature methanol washing device as raw material, uses advanced synthesizer indirect production ethylene glycol technology, can not only reduce the dependence of crude oil import, but also realize the clean and efficient utilization of coal, marking a new breakthrough in the key technology of modern coal chemical industry in China, the synthesized gas glycol industry entered the "big device" era.pictured is the scene of the press conference
    this is the reporter from November 28 in Beijing, "China's single set of the largest and most efficient synthetic gas glycol device successfully put into production" press conference was informed of the .
    The President of the Petroleum and Chemical Planning Institute Gu Zongqin, the former president of the China Coking Industry Association Jingan, the president of the China National Chemical News Agency Cui Xuejun and other government agencies, industry associations, related enterprises, as well as CCTV Network, The Central People's Radio, Science and Technology Daily, China Chemical News, China Chemical Network and other news media reporters nearly 100 people attended the press conference.
    understood that recently, by Ningbo Zhongke Far East Catalytic Engineering Technology Co., Ltd. development, Shandong Hualu Hengsheng Chemical Co., Ltd. annual output of 500,000 tons of large-scale glycol device through the entire process. On November 13, the plant's production load reached 100%, with a daily output of 1490 tons, close to the design value of 1500 tons per day, and a premium yield of 100%.Zhao Bo, marketing director of
    China Science and Technology Far East, said at the press conference that the successful driving of the device has set a number of records: the shortest driving time of the ethylene glycol device; As the first large-scale 500,000 tons of ethylene glycol demonstration project, research and development and construction on the basis of no precedent to follow, and in a month and a half quickly reached 100% full load, and the plant operation is stable, product quality is excellent, proving that the Chinese Science and Technology Far East synthesizer glycol technology mature and reliable, good performance.
    Hualu Hengsheng Deputy Chief Engineer Gao Wei said that the construction of 500,000 tons of ethylene glycol plant is a major decision and initiative of the company, in the tacit cooperation and efforts of all parties, quality and quantity on schedule to complete the construction task, the smooth completion and commissioning of the plant is a major milestone in the history of Hualu Hengsheng.
    , vice president of China Chengda Engineering Co., Ltd., said the device faces three major technical challenges: the largest single unit, the largest, the largest equipment, and the large diameter thin-walled tube. In the project design, construction, test drive, put into production process, through the joint efforts of all parties, set a successful feeding drive, production standards take the shortest time, excellent product quality, key equipment, process large-scale, all equipment materials localization, investment savings and other impressive results.
    according to Dr. Li Tong of The Ningbo Materials Institute of the Chinese Academy of Sciences, the Far East of The Chinese Academy of Sciences, relying on the Ningbo Materials Institute of the Chinese Academy of Sciences, has carried out a large number of detailed basic experiments, so that the large-scale device can be relied upon. The entire process package is complete and covers scientific research, engineering, technology and production. So that the whole project from the early demonstration to start construction, and then to run production are very smooth, each stage can reasonably cross, methodical, and really achieve organic integration.
    that in 2013, the Far East successfully developed a key catalyst for synthesized gas glycol, and completed 200,000 tons of glycol process package expert review. In March 2014, hualu Hengsheng 50,000 tons of glycol industrial equipment for line testing. In May 2015, Hualu Hengsheng 50,000 tons of ethylene glycol plant technology reform completed into operation, the plant operation is stable, low production costs, product quality reached polyester grade, excellent product rate reached 100%, all products are used in the polyester industry.
    July 2016, China Science and Technology Far East and Hualu Hengsheng signed a 500,000-ton ethylene glycol technology contract, taking the lead in the construction of the largest production plant of coal glycol in China. The device is optimized on the basis of the operation of the 50,000-ton device, and uses the cutting-edge technologies such as DMC separation, nitric acid reduction and distillation using thermal coupling.
    Pointed out that high-quality development is a new issue in the development of each industry. Hualu Hengsheng 500,000 tons / year synthesizer glycol device is through multi-party cooperation, joint breakthrough results, fully reflects the characteristics of high-quality development. The project has the following characteristics: large single set of scale, high technical difficulty, low investment cost, fast construction speed, good economic benefits. He believes that the technology is a new breakthrough in the coal glycol industry, is an innovative result, exciting.
    data show that glycol is mainly used in the production of PET, accounting for about 90% of the total consumption, other used in the production of antifreeze and fine chemicals. As the world's largest polyester producer and market, China is also the world's largest consumer of glycol. For a long time due to raw material restrictions, China's glycol production capacity growth rate is limited, while domestic demand growth rate remains high, the domestic demand for glycol is expected to reach 15 million tons in 2020. However, China's external dependence on glycol remains high, with a total production capacity of about 8.4 million tons in 2017, a production capacity of 6.58 million tons, an import volume of 8.71 million tons, and an external dependence of up to 57%.
    , glycol synthesis routes can be divided into two categories: petroleum synthesis routes and non-oil synthesis routes. Among them, coal glycol technology stands out in the non-oil synthesis route, with the continuous maturity of the technology, has become the main force in the development of glycol. It is understood that the current production capacity of petroleum-based glycol about 56%, coal-based glycol about 35%, the rest of the methanol glycol.
    , marketing director of The Far East of China Science and Technology, believes that the new technology can completely replace the technical route of petroleum legal glycol and improve China's ethylene glycol self-sequincability. Next, China Science and Technology Far East intends to enter the capital market and become an international first-class catalytic engineering technology research and development company.
    experts at the meeting said that under the background of china's coal-rich oil and gas shortage, the development of coal-based glycol large-scale technology, help to fill the huge gap in the domestic market, and then drive the development of downstream polyester industry. This not only opens up a new way for the clean and efficient use of coal, but also guarantees the national energy security and energy structure optimization.
