| titleOfInvention | A kind of octafluoropropane purification process |
| abstract | The invention discloses a kind of octafluoropropane purification process, comprising: octafluoropropane raw material is carried out normal temperature absorption under normal temperature condition; By the described octafluoropropane raw material that adsorbs through normal temperature at-37 DEG C ~ 10 DEG C, under 0.1 ~ 0.6MPa condition, carry out rectifying; Described octafluoropropane raw material through rectifying is carried out cryogenic absorption at-100 DEG C ~-30 DEG C temperature; Carry out pressurized adsorbent by under the pressure condition of the described octafluoropropane raw material through cryogenic absorption at 0.5 ~ 1.5MPa, obtain octafluoropropane product.Adopt the present invention, not only remove most of chloride fluorocarbons impurities in octafluoropropane raw material, and in solution prior art, carbonic acid gas and water remove the inadequate problem of the degree of depth, reduce energy consumption, strengthen the adsorption effect of sorbent material, make octafluoropropane product reach purity more than 99.999%. |
