The optimum ratio depends on the target output of di- and triethylene glycols\nGenerally applicable\nb.\nIsolation of by-products at EO plants for use\nFor EO plants, the concentrated organic fraction obtained after the dewatering of the liquid effluent from EO recovery is distilled to give valuable short-chain glycols and a heavier residue\nOnly applicable to new plants or major plant upgrades\nc.\nIsolation of by-products at EG plants for use\nFor EG plants, the longer chain glycols fraction can either be used as such or further fractionated to yield valuable glycols\nGenerally applicable",
