Three hidden worries of coal to ethylene glycol

wallpapers Industry 2020-12-09

coal-based syngas was hydrotreated to ethylene glycol via oxalate hydrogenation route. In 2009, it was listed as one of the five modern coal chemical industry demonstration projects by the national development and Reform Commission. A series of achievements have been made so far. According to the

and

Asian consultation data, Xinjiang Tianye (600075, The operating load of the 50000 T / a syngas to ethylene glycol project of Guba) reached 96%; the annual load of Tongliao Jinmei was 76%, of which the average load in the second half of the year was 89%; the ethylene glycol products of Hubei chemical fertilizer of Sinopec were mainly digested by Yizheng Chemical Fiber Co., Ltd.; the ethylene glycol products of Yongjin Anyang of Henan Coal Chemical Co., Ltd. were mainly used by polyester factories built by Henan Coal Chemical Co., Ltd. Although the development of

and

is full of opportunities, the opportunities are limited. The original intention of developing coal to ethylene glycol is to supplement the domestic ethylene glycol supply and demand gap and apply it to downstream polyester industry on a large scale. From 2009 to 2014, the import volume of ethylene glycol increased year by year, and the domestic coal to ethylene glycol did not form an important supplement as scheduled, which has a very obvious gap compared with coal to polyolefin. Since the beginning of 2015, the development speed of coal to ethylene glycol has been significantly accelerated, but it also faces the following three hidden worries. One of the hidden worries of

and

: the raw material competition between low oil price and cheap ethane. Since June 2014, the international oil price of

and

has declined, which has enhanced the cost competitiveness of ethylene glycol in China's domestic oil route. At the same time, the shale gas revolution in the United States, which began in 2008, and ethane, a byproduct, have increased the attractiveness of investment in the US petrochemical industry. Several new ethylene plants are planned to be put into operation by 2019. At present, the downstream product planning is mainly polyethylene, but the production capacity of ethylene glycol may be increased in the future. The second worry of

and

is the competition of alternative technical routes. Ethylene glycol of oxalate hydrogenation route of

and

is the mainstream of the development of coal to ethylene glycol. However, there are still two routes for using coal (or methanol) as raw material. The first is coal (methanol) to olefin (CTO / MTO), and then ethylene glycol is produced by ethylene through the traditional petrochemical route. DMTO of Ningbo Fude adopts this route and is operating an ethylene glycol project with a capacity of 500000 tons / year. Second, Eastman Chemical Co., Ltd. announced in October 2013 that it cooperated with JM David Technology Co., Ltd. to develop an advanced patented technology for producing ethylene glycol from syngas without passing through oxalic acid intermediates. The technology has entered the pilot stage. The third hidden trouble of

and

: environmental pressure

and

have been formally implemented since January 1, 2015. More and more attention has been paid to environmental protection measures of coal chemical industry, and coal to ethylene glycol is no exception. In March 2015, the annual output of 200000 tons of coal to ethylene glycol project under construction by Henan coal chemical Anyang Yongjin Chemical Co., Ltd. was ordered to stop the pilot production and fined 100000 yuan by the environmental protection department of Henan Province at the end of 2014 due to the inconsistency between the sewage treatment process and the original EIA reply. Up to now, the revised EIA change report has been completed and submitted to Henan environmental protection department for re evaluation. Yahua consulting believes that modern coal chemical projects, including coal to ethylene glycol, will face more stringent environmental protection requirements.

and

think that coal to ethylene glycol, like coal to olefin, has the potential to change the raw material structure of China and realize the diversification of ethylene glycol raw materials. At the same time, it should be noted that although the opportunity window of coal to ethylene glycol still exists, it has begun to narrow. We need to recognize the hidden worries of the industry development and explore the way to deal with it as soon as possible. The sixth technical and economic seminar on coal to ethylene glycol will be held in Nanjing on April 27. The industry will jointly discuss the raw material competition between low oil price and cheap ethane, a by-product of shale gas in the United States, the progress of new alternative technology routes, the impact of new environmental policies on coal chemical industry and coal to ethylene glycol, and the bottleneck of large-scale application of coal to ethylene glycol products and countermeasures.
