How Much Do You Know About MEG Plant?

图片
End uses for MEG range from clothes and other textiles, through packing to kitchenwaresearch engine coolants and antifreeze. Polyester and fleece fabrics, upholstery, rugs and pillows, in addition to mild and sturdy polyethylene terephthalate drink and food containers originate from ethylene glycol. The humectant (water attracting) properties of MEG products also make them perfect for use in fibres therapy, paper, adhesives, printing inks, leather and cellophane. MEG is a colourless, odourless liquid with a syrup-like consistency. 55% of MEG is used to make polyester fibres. 25% of MEG is employed in polyethylene terephthalate - or PET - packaging and bottles. 45% of the planet's MEG output is consumed in China. Global MEG demand was approximately 21 million tonnes in 2010. Forecasts indicate that by 2015, demand could be above 28 million tonnes each year. In China, MEG need continues to grow at around 7 percent every year. Shell opened among the world's biggest MEG ...

Know More About The Production of Methyl Acetate

The  Methyl Acetate Manufacturing Process , moreover retaining its usefulness from solvent applications, is gaining significance as an intermediate in the production of other valuable goods. Due to its unfavourable physical attributes (viz. Article of azeotropes and solubility in water) pure methyl acetate containing low levels of methanol and water isn't readily obtainable using traditional procedures. A traditional esterification procedure which may be used for its production of methyl acetate comprises the addition of a feed mixture comprising extra methanol and acetic acid into an esterifier containing aqueous acetic acid and a solid acid catalyst (e.g. toluene-para-sulphonic acid) under reflux conditions. A normal ester distillate product obtained by use of a 2:1 molar ratio feed of methanol:acetic acid must comprise 59.9percent w/w methyl acetate, 26 percent w/w methanol and 14.5% w/w water. Conventionally purification of such a crude ester distillate is effected at a multi-...

How Much Do You Know About MEG?

Monoethylene glycol (MEG), also known as ethylene glycol (EG) or simply glycol, is a diol mostly employed for its production of polyester fibers and polyethylene terephthalate (PET) resins. It is also utilized in antifreeze programs and in pharmaceuticals and cosmetics. MEG is produced through the hydrolysis of ethylene oxide (EO), which is obtained via ethylene oxidation. From the described process, MEG is produced via EO, which is fabricated in an integrated plant using Shell EO technology. An important characteristic of the procedure is the minimal production of diethylene glycol (DEG) and triethylene glycol (TEG), which occur as byproducts in other ethylene glycol production processes.

Alkyl Phenol Production Process

图片
A procedure for the creation of unsubstituted and lower alkyl substituted p-aminophenols. A charge mixture is prepared containing an unsubstituted or lower alkyl substituted nitrobenzene substrate, a platinum catalyst and a sulfur compound. The sulfur compound might be a divalent sulfur compound where sulfur is bonded to two other moieties or a compound reducible to these sulfur chemical beneath catalytic hydrogenation conditions. Hydrogen is introduced into the mixture while it's agitated at a temperature of 0.degree.-40. degree. C., thereby reducing the substrate to an unsubstituted or alkyl substituted phenylhydroxylamine. The hydroxylamine is thereafter heated to a temperature of at least 70. degree. C. and agitated at least 70. degree. C. in the presence of a highly dissociated acid, therefore effecting rearrangement of the hydroxylamine to the corresponding p-aminophenol.

Separation of Crude Aromatics

图片
crude aromatics separation process has the advantages of advanced process flow, high process flexibility, low process energy consumption and high yield. With the separation of C10 crude aromatics from 60 thousand tons / year as an example, the high boiling point solvent products have the characteristics of high aromatic content, strong solubility, low toxicity, small smell, high flash point, high boiling point, moderate volatilization speed and stable chemical and physical properties. It has no chlorine and heavy metals. Its physical and chemical properties are stable and leveling is good. Its solubility is excellent. Especially in the later stage of evaporation, it can exert high dissolving force, so that the smoothness of the coating is good without orange peel and gloss. In addition, it can also be used as cleaning agent for precision machinery and pesticide emulsifier. It is an ideal solvent for producing high grade paint, paint, diluent, ink, adhesive, oil additive and high tem...
