| Abstract: | The status of supply-demand and technological advancement of ethylene glycol in the world were described. It is forecasted that from now on, annual growth rate of demand will be 6%~7%. New ethylene glycol manufacturing process of MCC was introduced. The process has more than 99% high selectivity coefficient of MEG and n(H_2O)/n(EO) rate of approach to stoichiometric coefficient; and investment/operational cost is low. It will become the first select of ethylene glycol large plant. |
