Systems and methods for acetylene purification |
| abstract |
The invention includes methods for removing higher acetylenes from a gaseous stream that includes a hydrogen fraction and a non-hydrogen fraction, wherein the gaseous stream includes less than about 4% in total of di acetylene and vinylacetylene, where the method includes the following steps: (i) an adsorption that passes the gaseous stream at a preselected superficial linear gas velocity across an adsorption bed supported within an enclosure, the adsorption bed containing a crystalline porous ceramic adsorbent to adsorb the higher acetylenes onto the adsorbent, thereby producing a saturated adsorption bed and a purified gaseous stream including less than about 25 ppm of diacetylene that regenerates the saturated adsorbent bed by passing a regeneration gas across the saturated adsorption bed to desorb the higher acetylenes retained thereupon, thereby producing a regenerated adsorbent bed and a contaminated gas stream bearing the higher acetylenes; and (iii) a purging step that removes the contaminated gas stream from the enclosure. The invention also includes systems for removing diacetylene and vinylacetylene from a hydrogen-dominant acetylene-hydrogen gaseous stream. |
