Abstract: With the increasing demand for environmental protection, exhaust gas absorption towers have been applied in various industries. This paper adopts well-established empirical formulas to systematically design the specifications and main process performance parameters of the ethylene oxide absorption tower. Although the study only focuses on the design of the ethylene oxide exhaust gas absorption tower, the methodology can also provide valuable reference for the design of exhaust gas absorption towers containing other process media.

Key words: exhaust gas absorption tower, tower diameter, packing height, number of mass transfer units, height of a transfer unit
