Abstract
"Process for producing ethylene oxide" by the partial oxidation, of high purity ethylene by means of very pure oxygen in the presence of a catalyst containing silver, characterized in that they are operated with a reaction zone with purification and repeated cycle, using an entrance to said zone having an ethylene concentration of the order of 7 to 30%, an oxygen concentration of the order of 1 to 10%, a concentration of carbon dioxide of the order of 0.1 to 10%, an inhibitor concentration halogenated in the order of 0.0001 to 100 parts per million, a ballast gas concentration of the order of 0.05 to 70%, a reactor temperature in the order of 150 to 400º C, a reactor pressure of the order of 3 , 51 to 45.69 kg/cm2, a fluidity of the order of 2.41 to 42.48 m3, under normal conditions per hour per elongated zone with the diameter of the area average in the range of 12.7 to 50.8 mm, and the length of the area in the order of 1.52 to 12.19 m, being controlled the particular combination of conditions to achieve a selectivity of the order of 65 to 75%, a conversion of the order 10 to 30%, and a concentration of ethylene oxide in the outlet gas of the order of 0.3 to 5.0% being the purification of the system in the order of 0.01 to 0.1% based on the volume of ethylene introduced.
