Ethylene oxide (EO) and ethylene glycol (EG) are widely used industrial organic intermediates. %PDF-1.6 %�� Biological routes for ethylene glycol production have been developed in recent years by constructing the synthesis pathways in different microorganisms. Hence, there will be several side reaction which is ethylene glycol will react with water to form diethylene glycol and the diethylene glycol will react with water to form triethylene glycol. Synonyms: Ethylene glycol Industrial/Ethylene glycol Meglob-al/Glycol/Solv Ethylene glycol, SECTION 4. In 1995, their production volumes ranked them among the top twenty organic chemicals in the United States. The main advantage of the process is production of pure ethylene glycol without the need for further purification. Mono-Ethylene Glycol Production Capacity by Region. Ethylene oxide is also used as a sterilizing agent for medical equipment and a fumigating agent for spices. Volume 178, 2019, Pages 173-193. 144 0 obj <> endobj General ethylene furnace schematic I.

The world MEG production capacity for the year 2016 was 34.8 million tons. Ethylene glycol (EG), one of the important basic chemical raw materials, is widely used in producing polyester and antifreeze (Wei et al., 2018).As the production capacity of polyester increases year by year, the demand for ethylene glycol is greatly stimulated. Figure 1 depicts MEG production from ethylene via a process similar to the OMEGA catalytic process from Shell Global Solutions (The Hague, the Netherlands; www.shell.com). Introduction. For each major industrial source category described in Sections 4 and 5, example process descriptions and flow diagrams are given, potential emission points are identified, and available The global production was dominated by Asian countries which accounted for 15.1 million tons from the total production. Version 1.4 Revision Date: 05/07/2015. See Health Information. Furnace The two primary feedstocks for ethylene production are naphtha and natural gas (ethane, propane, butane, etc.).

There, ethylene glycol (MEG, Monoethylene glycol) is produced from EO by reacting it with water at a 10 to 1 ratio of water to EO. However, a production of ethylene glycol through hydrolysis of ethylene oxide needs a lot of water in the reaction phase reaching production specification which cause a high-energy demand in water distillation unit (Rao et al., 2007). endstream endobj 149 0 obj <>stream Other derivatives of ethylene oxide include: diethylene glycol, which is used in the production of polyurethanes, polyesters, softeners (cork, glue, casein and paper), plasti- ethylene glycol in windshield deicers; caulking, glazing, and drywall compounds; and latex paints. Asia holds a prominent share in the global market production of MEG In 1995 the world capacity for ethylene glycol was about 9.7 x 106 tonnes per year. Xylonic acid utilizing microorganisms were screened from natural environments, and an Enterobacter cloacae strain was isolated.
