Ethylene Oxide/Ethylene Glycol (EO/EG):

Scientific Design’s Ethylene Oxide/Ethylene Glycol (EO/EG) technology provides the safest and most efficient means for producing high purity EO and/or fiber-grade monoethylene glycol (MEG). These products are used in many important derivative processes (several licensed by Scientific Design) to make a wide variety of industrial and consumer goods such as polyester fibers, polyethylene terephthalate (PET) bottles, and antifreeze consuming about 15% of the world wide production of ethylene. In addition to superior product quality, Scientific Design’s EO/EG technology in combination with its high performance Syndox® catalysts. 

Technology Highlights:

  • Safe operation as proven by Scientific Design’s unparalleled safety record for plants designed to handle hazardous hydrocarbon/oxygen reaction mixtures and purified EO
  • Proven performance of more than 100 EO/EG plants worldwide including some of the world’s largest
  • Low capital and operating costs as a result of highly integrated designs and economies of scale
  • Equipment that enables optimal Operation

Ethylene and oxygen are combined to produce EO in a multi-tubular catalytic reactor in the presence of catalyst. The highly exothermic reaction is carefully controlled with proprietary and effective safety systems developed by Scientific Design. EO produced in the reactor can be separated to high quality purified EO and/or further processed to produce fiber-grade monoethylene glycol (MEG) as well as di- and triethylene glycols (DEG, TEG).
