Petelyse-PET Recycling
Veselý, Václav ; Kouřil, M.
Report sumarised up the results of project petelyse-chemical recycling of PET boltes. The analytical method was valided for watching of a technologie. The data from pilot plant was ground of design and material and energy balance and development of aparates. This report was base for feasibility study of process chemical PET botles recycling.
Petelyse-PET Recycling
Veselý, Václav
Chemical recycling of PET to terephtalic acid and ethyleneglycol is carried out in two stages through alkaline glykolysis and subsequent hydrolysis. The product of hydrolysis is elektrolicically further separated into terephtalic acid suspense and alkaline glykol solution. Crystallic terephtalic acid separates from the suspense and once washed is dried. Vacuum istilation is applied to get ethylenglycol.
