Ethylene glycol (EG) production via coalbased syngas has been demonstrated to be an attractive process with a higher conversion and lower energy consumption. However, few researches are focused ...
As of May 14, combined ethylene glycol inventories increased 22,500 tonnes from million tonnes at eastern ports, data showed. Judging from the current maintenance situation, the domestic ethylene glycol production will drop to around 600,000 tonnes in May, but low operating rate may help to mitigate oversupply status.
Jan 06, 2017· Now, it can be made from multiple raw materials, such as coal, natural gas and ethylene. Globally, it is mainly produced from ethylene via an ethylene oxide intermediate. This process generates di and triethylene glycol along with MEG. The process In the process described here, ethylene glycol is produced from synthesis gas (syngas), a ...
Nov 05, 2007· Ethylene glycol used to be manufactured by the hydrolysis of ethylene oxide (EO) which was produced via ethylene chlorohydrin but this method has been superseded by a direct oxidation route. The EO is first produced by the oxidation of ethylene in the presence of oxygen or air and a silver oxide catalyst. A crude ethylene glycol mixture is then produced by the hydrolysis of EO with water .
Oct 01, 2015· Ethylene glycol production and purification. Ethylene oxide is reacted with CO 2, forming ethylene carbonate, which is then hydrolyzed to form MEG and CO 2. Both reactions are carried out in the liquid phase using homogeneous catalysts. CO 2 streams from the reaction steps are recycled to the ethylene carbonate reactor. MEG is purified in two ...
Jul 15, 2018· The improved CtEG process can produce more ethylene glycol and has a better thermodynamic performance than the reference process. The ethylene glycol production of the improved CtEG process is increased from t/h to t/h, and the exergy efficiency is increased from % to %.
Jul 15, 2018· With the rapid development of polyester industry, the increasing demand of ethylene glycol (EG) is in conflict with the shortage of supply in China. Large project of EG production from coal has been receiving more and more attention.
Increasing demand of ethylene glycol conflicts with the shortage of supply, forcing Chinese government to seek for its alternative production routes. .
In a composite process for subjecting ethylene to catalytic gas phase oxidation thereby obtaining ethylene oxide and causing this ethylene oxide to react with water thereby obtaining ethylene glycol, a method for producing the ethylene glycol is provided which permits effective utilization of the energy at the step for dehydrating and concentrating the resultant aqueous ethylene glycol solution.
proprietary technology for the production of ethylene glycol from coal has been selected by Inner Mongolia Jiutai New Material (Jiutai) for its planned 1,000,000 tonnes per annum ethylene glycol facility. Ethylene glycol, commonly referred to as mono ethylene glycol (MEG), is a key industrial chemical
Ethylene glycol is produced from carbon monoxide in countries with large coal reserves and less stringent environmental regulations. The oxidative carbonylation of methanol to dimethyl oxalate provides a promising approach to the production of C 1based ethylene glycol.
Johnson Matthey and Eastman Chemical Company (Eastman) announce that their advanced, proprietary technology for the production of ethylene glycol from coal has been selected by Inner Mongolia Jiutai New Material (Jiutai) for its planned 1,000,000 tonnes per annum ethylene glycol facility.
Ethylene glycol, commonly referred to as mono ethylene glycol (MEG), is typically produced from ethylene. MEG is used as a building block in the production of polyesters for fibre and packaging applications. The new process allows MEG to be produced from syngas feedstocks, thereby eliminating the need for ethylene. The coaltochemicals ...
Brief introduction. The technology for synthesizing ethylene glycol from synthesis gas/industrial vent gas, instead of petroethylene, is a major part of the C1 chemical industry, whose use of raw materials is a more scientific, more reasonable, and economically superior to the use of petroleum.
Today, coalbased facilities represent about 40% of China''s ethylene glycol production capacity and 14% of actual output, according to Michael Zhao, another CCFGroup consultant. In five years, he expects coalbased facilities will account for 20% of the country''s output, while production capacity will be half of the country''s total.

The new coal to ethylene glycol (CtEG) technology involves the production of ethylene glycol from coal. CtEG is far more economical than production from naphtha. The increasing awareness and ...
Published October 2012. This review presents a technoeconomic evaluation of a newly commercialized monoethylene glycol (MEG) production route, which, if it successfully meets the desired level of product purity and catalyst stability, could revolutionize the MEG industry with the possibilities of switching its production from the current ethylenebased source to a new coalbased source.
Jul 05, 2016· Among these products, ethylene glycol (EG) is an important bulk chemical with an annual production and consumption of more than 20 million tons 6. As a prevalent industrial product, this C2 diol finds widespread applications in different fields, for example, as a solvent, antifreeze agent and precursor for the manufacture of polyester fibres ...
Ethylene Glycol MEG was first synthesized via the hydrolysis of ethylene glycol diacetate. Now, it can be made from multiple raw materials, such as coal, natural gas and ethylene. Globally, it is mainly produced from ethylene via an ethylene oxide intermediate. This process generates di and triethylene glycol along with MEG. Ethylene Glycol
