This supplementary report presents updated technical and economic information on two processes, and new information on a third process for producing monoethylene glycol (EG):
- EG from Ethylene via Ethylene Oxide. This is the conventional method by which most EG is made at present. Information in PEP Report 70A is updated.
- EG from Ethylene via Glycol Esters. An updated design and economic study, superceding that in PEP Report 70A, is presented, on the basis of using Halcon catalysts.
- EG from Ethylene by Direct Oxidation. A process for oxidation of ethylene directly to EG is evaluated. This is SRI International's first evaluation of this process. The evaluation is based on the use of a Teijin catalyst.
