Abstract: The present invention describes a n-butane absorption process for purifying the ethylene product from an ethane oxidation process. The ethane oxidation product is fed to a series of absorption towers using a n-butane solvent that remove the inert components as well as purifying the ethylene from the product. A first absorption tower uses n-butane as a solvent to absorb both the ethane and ethylene, allowing for inert gasses to be removed from the stream. An ethylene-rich side stream from this tower is sent to an ethylene purification tower where ethylene is purified using n-butane solvent. The bottom stream from the first absorption tower is then sent to an intermediate ethylene recovery tower where crude ethylene is purified, and the overhead ethylene stream being sent to the ethylene purification tower.

Abstract: Described herein is a process in which acetic acid is produced by ethane oxidation. One byproduct of the ethane oxidation is water, which is commonly removed from the process in the same stream as the acetic acid process. As described herein, the ethane oxidation reactor effluent is processed in a predehydration tower so as to separately recover water, acetic acid, and a gas stream for recycle back to the ethane oxidation reactor.
