The sorbents were prepared by the incipient impregnation technique, and the vanadium loading and the calcination temperature were varied. The sorbents were tested in a packed-bed microreactor set-up for five sulfidation-regeneration cycles to investigate their breakthrough behaviour. Sulfidation was performed at 873–973 K with H2S-H2-H2O-N2 mixtures, while regeneration was carried out at 923–973 K with O2-N2 mixtures. The fresh, sulfided, and regenerated sorbents were characterized by atomic absorption spectroscopy, X-ray diffraction, surface area and porosity measurements. The results of the investigation indicated that the sorbents exhibited a more stable cyclic performance with higher vanadium loading, all vanadium-promoted sorbents reduced the H2S content of the gas to levels below the equilibrium level for zinc oxide, some H2S was chemisorbed by vanadium, and two-step calcination imparted structural stability to the sorbents.</div>","PeriodicalId":12586,"journal":{"name":"Gas Separation & Purification","volume":"9 1","pages":"Pages 17-25"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0950-4214(95)92172-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85525493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In flammability tests, violent energy releases were observed with the strong promoter thermite; however, no differences in flammability between sieve trays and packing were noticed.

The models consider transient behaviour of the enrichment process, the effects of permeability functions, flow patterns and separation of multicomponent systems. The gas mixture considered in the analysis includes CH4, CO2, N2 and H2S. Comparison of models shows that for either flow pattern, the presence of low permeating species reduces the final CH4 mole fraction in the enriched mixture. In addition, higher CH4 recoveries are predicted by the four-component model than by the binary model. This is a result of the lower driving force for permeation in the four-component model, caused by lower mole fractions. Similar behaviour is also predicted for the removal of CO2 and its final mole fraction in the gas mixture. The presence of other fast permeating species (H2S) resulted in lower permeation rates of CO2. As a result, higher CO2 mole fractions in the gas mixture and lower CO2 removal are predicted by the four-component model. The use of variable permeabilities versus constant permeability ratio showed similar predictions for some of the system variables with partial matching between model predictions at either low or high pressure.</div>","PeriodicalId":12586,"journal":{"name":"Gas Separation & Purification","volume":"9 1","pages":"Pages 3-11"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0950-4214(95)92170-H","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90547307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the safety of trays and packing depends entirely on the exclusion of ignition mechanisms.This paper presents an evaluation of ignition mechanisms with respect to their relevance to the adiabatic section of the column. The combustion of hydrocarbons has been identified as the only realistic ignition mechanism. Therefore, most of the experiments described in the paper refer to this mechanism. It is shown that the combustion of an oil film on packing (approximately 5 g m−2) is not able to ignite aluminium packing, but that accumulated oil (a few grams) is able to ignite aluminium trays and packing as well as copper packing. This result stresses the importance of controlling any hydrocarbon accumulation.A short review of accumulation mechanisms for lubrication oil from fabrication and hydrocarbons from air shows that accumulation within the adiabatic section of the distillation column is practically impossible.Finally, it is concluded that no ignition sources for aluminium trays and packing are present in the low-pressure column of oxygen distillation columns. This explains the very good safety record of aluminium trays for more than 30 years of industrial experience characterized by no single case of tray combustion. Aluminium packing, now in operation for more than five years, can be expected to be as safe as trays.</div>","PeriodicalId":12586,"journal":{"name":"Gas Separation & Purification","volume":"9 1","pages":"Pages 59-67"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0950-4214(95)92178-F","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75819837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
