Although the production capacity and output of ethylene oxide in China have increased in recent years, and will show an increasing trend in the next few years, due to the rapid development of polyester and surfactants, ethylene oxide is far from meeting the needs of the domestic market. Tight supply patterns are difficult to change in the short term.
The capacity of the device is large and the amount of goods is small. At present, there are 12 sets of ethylene oxide production devices in China, and most of the devices are co-produced with ethylene oxide and ethylene glycol. In 2007, the ethylene oxide plant capacity reached 2.1 million tons. Although in recent years China's ethylene oxide production capacity and production have greatly increased, but in actual production process, some ethylene oxide devices only produce part of ethylene oxide, and some devices are even used to produce ethylene glycol. . Therefore, the real ethylene oxide product volume only accounts for 33% of the total capacity. In 2007, the volume of ethylene oxide products was approximately 650,000 tons. Although the volume of ethylene oxide products increased by 500,000 tons in 2006, the overall increase in production was slow and could not meet market demand.
Restricted import, too concentrated layout
Because the boiling point of ethylene oxide at atmospheric pressure is only 10.7°C, long-distance transportation can easily cause self-explosion, which determines that ethylene oxide cannot rely on imports to make up for the inadequacies of the domestic market. The demand for ethylene oxide can only rely on domestic production.
At present, domestic ethylene oxide production capacity is relatively concentrated in Jiangsu, Zhejiang and Shanghai. Nanjing Yangtze-BASF’s new 300,000-ton/year installation, Sinopec Yangzi Petrochemical’s 262,000-ton/year installation, Shanghai Petrochemical’s new 300,000-ton/year installation, plus the original 300,000-ton/year installation, with a total capacity of 60 Ten thousand tons / year, Jiaxing Sanjiang Chemical newly built 60,000 tons / year device. The production capacity of ethylene oxide in the above-mentioned regions accounts for 58% of the country's total. The rise and fall in ethylene oxide prices in this region will directly affect other domestic markets. In addition, due to the impact of the soaring international crude oil prices, under the effect of the product industry chain, the high price of ethylene and ethylene oxide will not change under the current situation of increasing production costs.
The downstream demand has increased, and the market gap has been large . Since 2007, the demand for ethylene glycol, synthetic detergents, surfactants and other products has been increasing, especially the rapid development of the ethylene oxide deep processing industry. Ethylene oxide is derivatized. The market space for specialty chemicals has been greatly expanded. A fine petrochemical product cluster has been formed for the downstream processing of ethylene oxide. Ethoxylates, pyridazines, ethylene carbonates and hydroxyethyl compounds have been widely used in civil washing and industrial cleaning. Petrochemical, metal processing, pesticides and pharmaceuticals, textile printing and dyeing, rubber and plastics, and papermaking industries. The ethylene oxide demand for fine chemicals in recent years is increasing at a rate of 10% per year.
In addition, the shortage of domestic ethylene oxide is also reflected in the huge number of downstream products imported. The import of major downstream products showed a rapid growth momentum. About 70% of domestic ethylene oxide production capacity was used to produce ethylene glycol, glycol ether and ethanolamine. In December, the spot price of imported ethylene glycol hit an all-time high, rising to the current $1,700 (land-to-shore net water price). According to industry analysts, the price may also break through the $1800 mark. According to incomplete statistics, since 2003, the total amount of ethylene oxide downstream products imported by our country has exceeded 2.4 million tons, which shows that the supply and demand gap of ethylene oxide will continue to increase.
Industry experts called for a large gap in the domestic market for ethylene oxide, the market prospects are vast and urgently needed rapid development. It is recommended to accelerate the digestion and absorption of advanced foreign technologies while introducing large-scale ethylene oxide/ethylene glycol units, actively develop domestic technologies, develop large-scale ethylene oxide reactors, and build large-scale ethylene oxide boilers in ethylene production sites. Alkane device, which eases the domestic supply of ethylene oxide market situation.
Ethylene market is full of enthusiasm
In 2007, the domestic ethylene oxide price has been unilaterally rising. The price has risen from 12,500 yuan (t price, the same below) at the beginning of the year to 17,500 yuan in November, setting a record high. In particular, the increase of more than 1,500 yuan in November has attracted special attention.
