Brief introduction. The technology for synthesizing ethylene glycol from synthesis gas/industrial vent gas, instead of petro-ethylene, 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.
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 ...

Ethylene glycol (EG) production via coal-based syngas has been demonstrated to be an attractive process with a higher conversion and lower energy consumption. However, few researches are focused ...
Today, coal-based 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 coal-based facilities will account for 20% of the country's output, while production capacity will be half of the country's total.

Monoethylene Glycol, MEG) is an organic compound, more specifically a diol (a chemical compound that contains two hydroxyl groups).
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.
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by the hydrolysis of ethylene oxide (EO) which was produced via ethylene chlorohydrin but this method has been superseded by a direct oxidation route.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 .
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 37.50 t/h to 38.64 t/h, and the exergy efficiency is increased from 30.68% to 31.49%.
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 ...
Ethylene glycol ("MEG") is an 18.9 million ton global market growing at on average at 3.7 percent per year. Around 72 percent of the market is focused on the Asia-Pacific region with China accounting for 60 percent of demand in this ... gasification for acetyls production, indicating that certain coal based chemistries are commercially viable
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 tri-ethylene glycol along with MEG. Ethylene Glycol
This Project report deals with the design calculations of Mono Ethylene Glycol production from Ethylene Oxide as a feed stock along with their relevant aspects such as instrumentation and process control, Hazop study and cost estimation.
The route and process, if they succeed commercially and achieve the desired level of product purity and catalyst stability on a sustained basis, could have a huge impact on the MEG industry with the possibilities of switching its production from the current ethylene-based source to a natural gas or coal .
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, anti-freeze agent and precursor for the manufacture of polyester fibres ...
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 1-based ethylene glycol.
Apr 15, 2020· Biological routes for ethylene glycol production have been developed in recent years by constructing the synthesis pathways in different microorganisms. However, no microorganisms have been reported yet to produce ethylene glycol naturally. Xylonic acid utilizing microorganisms were screened from natural environments, and an Enterobacter cloacae strain was isolated.
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 tri-ethylene glycol along with MEG. The process In the process described here, ethylene glycol is produced from synthesis gas (syngas), a ...
But the pace at which coal-based production is being implemented in China is spectacular. From nothing in 2011, China now has 3.5 million t of coal-based ethylene glycol capacity, says Cao ...
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 ethylene-based source to a new coal-based 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. .
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.
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.
