Faculty of Geosciences and Petroleum Engineering Universiti Teknologi Petronas 31750 Tronoh Perak Malaysia IntroductionParafn deposition problems have been recognized as one of the main challen. ETHYLENE GLYCOL Information Update ETHYLENE GLYCOLS Ethylene glycols Ethylene glycol aincluding diethylene glycol (DEG), triethylene glycol (TEG), pentaethylene glycol (PEG), and tetraethylene gly (Antifreeze). It was a case that had doctors and law enforcement in the small town of Perry, Okla. puzzled. What killed 53 year-old Carol Hellar? . Detection . According to the thousands of pages of information, Hellar’s only symptom that was inconsistent with a reaction to her medication was kidney failure. The records showed throughout her illness that Hellar had a steady decline in kidney function. At autopsy, significant levels of calcium oxalate crystals were found in her kidneys and brain, which could only be present as a result of a genetic disorder or ingestion of ethylene glycol, commonly known as antifreeze. .

Keone & Anthony. Ethane-1,2-diol. Formula : C2H6O2 (. C. 2. H. 6. O. 2. ). Ethylene Glycol is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its regular form, it is an odorless, colorless, syrupy, sweet-tasting liquid.. Steven Young. Department of Chemistry, University of New Hampshire, Durham, NH. May 1, 2015. Introduction:. Asahi Kasei Chemicals has improved on their phosgene-free process to produce polycarbonate by removing the need of ethylene oxide. Dynamic Wax Deposition Modeling. Wax Deposition. Wax is a solid deposit of long-chain paraffinic components (C. n. H. 2n+2. , n > 20) originally dissolved in crude oils..
