ABSTRACT
The production of ethylene glycol from used ethylene oxide was simulated by Aspen HYSYS? V9.0 based on actual data got from Ava-med for syringes in Khartoum. The effect of temperature and EO-water ratio on the EG mass flow was studied. Results showed that the amount of EG produced is 38.7 kg/h. As the temperature increased the mass flow of EG oscillated. The best temperature that gave the best amount of EG was 190oC. As the EO-water ratio is increased the EG mass flow is increased and the DEG byproduct is decreased. The ratio of EO-water in the Case Under Study (CUS) was 1:108 while the ratio that the literature recommended was 1:20, and it is found that the results were slightly improved in the CUS.
