Ethylene Glycol Production from Ethylene - Cost Analysis - MEG E12A
This report presents a cost analysis of Monoethylene Glycol (MEG) production from ethylene The process examined is similar to Shell OMEGA process. In this process, ethylene is first oxidized with oxygen to produce ethylene oxide, which is further converted to MEG. This report was developed based essentially on the following reference(s): (1) US Patent 8329959, issued to Shell in 2012 (2) US Patent 8217190, issued to Shell in 2012 Keywords: Ethene, Shell, OMEGA, Only MEG Advantage, Oxidation, Catalytic Process
Poly(Ethylene Glycol) Chemistry
The idea for this book came from discussions among participants in a symposium on biotechnical applications at the "Pacifichem 89" meeting in Honolulu. It was the majority opinion of this group that a volume dedicated to biotechnical and biomedical applications of PEG chemistry would enhance research and development in this area. Though the book was conceived at the Honolulu meeting, it is not a proceedings of this symposium. Several groups who did not participate in this meeting are repre sented in the book, and the book incorporates much work done after the meeting. The book does not include contributions in all related areas to which PEG chemistry has been applied. Several invited researc...
Ethylene Glycol
This publication, part of a series from the International Programme on Chemical Safety, evaluates the risk to human health and the environment posed by exposures to ethylene glycol, a clear, colourless liquid with a sweet taste but no odour. Estimated production capacity was 9.4 million tonnes in 1993, and release into the environment is mainly to the hydrosphere. The largest local release to surface waters would follow its use as a de-icer on airport runways and planes. On a world-wide basis, approximately two-thirds is used as a chemical intermediate, with a further one-quarter used as an antifreeze in engine coolants.
Ethylene Glycol
This book evaluates the risk to human health of ethylene glycol. Ethylene glycol is a colorless, odorless, sweet-tasting, relatively non-volatile liquid. It is used in the manufacture of poly-ethylene terephthalate, in natural gas processing, and as an antifreeze agent. Available data from acute poisoning cases (humans) and repeated-dose toxicity studies (experimental ani-mals), indicate that the kidney is a critical organ for the toxicity of ethylene glycol in both humans and experimental animals.

Corrosion of Materials by Ethylene Glycol-water
Solutions of ethylene glycol are being considered as beat-transfer media for radiators in manned space capsules. This report was prepared to summarize the available corrosion data on uninhibited and inhibited ethylene glycol solutions. Much of the corrosion data are based on automotive and diesel engine coolant systems. Several factors considered are: time dependence, effect of pH, concentration, temperature, aeration, chloride ion, velocity, heat- transfer rate, and galvanic couples. Inhibitors for which corrosion data are presented include: borax, sodium benzoate, sodium nitrite, triethanolamine, Sodium mercaptobenzothiazole, soluble oil, chromates, as well as miscellaneous inhibitors. A number of patented inhibitors based on borax are discussed. Descriptions of test procedures including automobile service tests are presented.
Ethylene Glycol Production from Carbon Dioxide - Cost Analysis - MEG E21A
This report presents a cost analysis of Monoethylene Glycol (MEG) production from carbon dioxide (CO2) using an electrochemical process. The process examined is similar to Liquid Light process. In this process, CO2 is electrochemically converted to oxalic acid, which is then hydrogenated to MEG.This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses:* Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capita...
Ethylene Glycol Production from Ethylene Oxide - Cost Analysis - MEG E32A
This report presents a cost analysis of Monoethylene Glycol (MEG) production from ethylene oxide. The process examined is similar to Shell OMEGA process. In this process ethylene glycol is produced from ethylene oxide, with ethylene carbonate as an intermediate. This report was developed based essentially on the following reference(s): Keywords: Shell, OMEGA, Only MEG Advantage, Oxidation, Catalytic Process, Mitsubishi
Heat-transfer Tests of Aqueous Ethylene Glycol Solutions in an Electrically Heated Tube
As part of an investigation of the cooling characteristics of liquid-cooled engines, tests were conducted with an electrically heated single-tube heat exchanger to determine the heat-transfer characteristics of AN-E-2 ethylene glycol and other ethylene glycol-water mixtures for a range of conditions.
