PROCESS DESIGN OF ETHYLENE OXIDE WITH
ANNUAL OUTPUT OF 55,000 TONS
ABSTRACT
The process of ethylene oxide with annual output of 5,5000 tons was
designed in this on the actual production process and production
theory reasonable design scheme was developed.
The status and role of ethylene oxide in the national economy was discussed
in this paper. Furthermore, the produce methods, the principle of produce and
process were also interpred. Material balance of the main equipments, such as:
the mixer, the reactor, the absorb tower of epoxyethane, and the absorb system of
carbon dioxide have been calculated. Calculation of energy balance for the
epoxyethane reactor were also carried out. Equipment calculations and checking
I / 36
word
of the reactor were carried on detail. The parameters, types and materials of the
equipments were confirmed. Based upon, the high purity epoxyethane rectifier
was draw using CAD. Finally, correspond measures for the production process
were given.
KEY WORDS：epoxyethane；process；reactor；material balance。
