Asian ethylene glycol supply may tighten in 2012
It is reported that due to the limited new production capacity and overhaul of equipment, the supply of ethylene glycol in Asia will tend to be tight in 2012. In 2012, only one MEG device will be put into operation in Asia. Ningbo Haoyuan Chemical Co., Ltd. invested 5.8 billion yuan ($922 million) to build a new 500,000 tons/year MEG unit in Ningbo, Zhejiang Province, and it is expected to start production in October.
In addition, there are some devices that will be shut down. Taiwan's South Asia Plastics Corporation plans to carry out scheduled maintenance work on the 720,000 tonne/year MEG No. 4 device in McCain in March. South Korea’s Hunan Petrochemical, China’s Yamba Petrochemical, India Trust Industry and Kuwait’s Equate have also planned to conduct 10-40 days of overhaul of MEG installations during the March-May period. The planned shutdown of these devices will affect 13% of the total MEG capacity in Asia, or 2.4 million tons/year. However, in the second half of 2012, the number of overhauled MEG installations in Asia will be greatly reduced. Until now, only Sinopec, which is part of Sinopec, will conduct a 40-day work stoppage on a 260,000-ton/year installation. A 360,000-ton/year joint venture facility in Tianjin will undergo a 40-50-day overhaul.
Sodium Acetate , CH3COONa, also abbreviated NaOAc, also known as sodium ethanoate, is the sodium salt of acetic acid. This colorless deliquescent salt has a wide range of uses.
For Industrial:It is used in the textile industry to neutralize sulfuric acid waste streams and also as a photoresist while using aniline dyes. It is also a pickling agent in chrome tanning and helps to impede vulcanization of chloroprene in synthetic rubber production. In processing cotton for disposable cotton pads, sodium acetate is used to eliminate the buildup of static electricity.
For Concrete longevity:It is used to mitigate water damage to concrete by acting as a concrete sealant, while also being environmentally benign and cheaper than the commonly used epoxy alternative for sealing concrete against water permeation.
For Food:It may be added to food as a seasoning, sometimes in the form of sodium diacetate, a one-to-one complex of sodium acetate and acetic acid, given the E-number E262. It is often used to give potato chips a salt and vinegar flavor.
For Buffer solution:As the conjugate base of acetic acid, a solution of sodium acetate and acetic acid can act as a buffer to keep a relatively constant pH level. This is useful especially in biochemical applications where reactions are pH-dependent in a mildly acidic range (pH 4-6).
