Mono-Ethylene Glycol Production Capacity by Region. H�\��n�0��y A multieffect evaporator train (13, 14, 15) is used to remove the bulk of the water from the glycols. One of the main pathways of biodiesel production is through transesterification. One plant with a production capacity of 200 000 tons of ethylene glycol per year is in Inner Mongolia, and a second plant in the Chinese province of Henan with a capacity of 250 000 tons per year was scheduled for 2012. The plant produces three derivatives of ethylene glycols -- monoethylene glycol (MEG), di-ethylene glycol (DEG) and triethylene glycol (TEG). Biodiesel is a biofuel alternative to petroleum diesel. The accuracy of the design parameters were ascertained by comparing predicted results with literature data of CSTR for production of propylene glycol. The present invention relates to a process for producing ethylene glycol from ethylene oxide wherein ethylene oxide in a gas resulting from oxidation of ethylene is absorbed in a specific absorbing solution, is allowed to react with carbon dioxide, converted into ethylene carbonate, and then subjected to hydrolysis to produce ethylene glycol. Through a streamlined process design, this results in lower capital and energy cost and higher raw material efficiency. In this work, the ethylene oxide/water molar ratio is 1: 7 and the yield of Ethylene glycol is 90%. Ethylene glycol (IUPAC name: ethane-1,2-diol) is an ...
