Introduction: 2017 is drawing to a close. In this year, the expansion of cathode material enterprises has been vigorous. The proportion of various technical routes has fluctuated, and profound changes have taken place in the field of cathode materials.

Production by continuous method. Solid sodium hydroxide dissolved in methanol, dissolved, after precipitation clarification, removal of solid impurities, clear water with a pump into the top of the reaction dehydration tower, refined methanol vapor from the bottom of the tower into the tower, through continuous reaction dehydration, from the bottom of the tower to obtain products. The water-containing methanol vapor enters the rectification system for refining after coming out from the top of the tower, and the anhydrous methanol vapor returns to the bottom of the tower.

That's up 14 percent from 5.82 million tons in 2009. According to Yahua consulting data, by the end of 2010, China's ethylene glycol production capacity was about 4 million tons, including 150000 tons of coal-to-ethylene glycol production capacity of Tongliao Gold Coal. In 2011, China will not have a large petrochemical route glycol project put into production. In 2011, if the operating rate of the domestic polyester industry is estimated at 75%, the output will be about 25.12 million tons and the consumption of ethylene glycol will be 8.54 million tons.
