COLUMN DESIGN NUMBER OF PLATES. Ethylene Glycol (EG) Ethylene glycol (C 2H 4(OH) 2) is produced from ethylene oxide through a catalytic reaction with water at higher temperature resulting in a yield of mono-ethylene glycol (MEG), known as glycol, and the by-products di-ethylene glycol (DEG) and tri-ethylene glycol (TEG). All … Davis Corporation contracted jEO & Associates to analyze the profitability of constructing a new ethylene oxide plant. will comprise less then 10 weight percent of the total glycol produced. In 2009 it was estimated that the world demand for ethylene was over 140 million tons per year, with an approximate yearly increase of 3.5%.

DESIGN OF REACTOR In the designing of a reactor, following things should be in mind. In 1995 the world capacity for ethylene glycol was about 9.7 x 106 tonnes per year. The growing biodiesel market has created an abundance of inexpensive glycerol, which can be converted into higher value products such as propylene glycol. The plant produces three derivatives of ethylene glycols — monoethylene glycol (MEG), diethylene glycol (DEG) and triethylene glycol (TEG). This report details a plant that produces 1MM tonnes of 99.96% pure ethylene per year from approximately 2.19MM tonnes of 95% ethanol, along with a thorough economic analysis. ethylene plant, what valve challenges those applications present, and the recommended Emerson solutions. endstream endobj startxref If you continue browsing the site, you agree to the use of cookies on this website.
