Is it feasible to temporarily change the oxygen-deficient process of the sulfur unit to an oxygen-rich process?

This sulfur treatment unit uses the Claus partial oxidation combustion process; recently, when the amount of acidic gases in the system was too high and it was necessary to increase the air supply, the high pressure in the sulfur system prevented further increases in air supply for combustion purposes. As a result, the overall processing capacity of the company was affected by this issue. After numerous meetings and analyses, as well as a thorough investigation of the issues, it was suspected that the pulverization of the catalyst inside the reactor was causing pressure buildup throughout the system. However, for certain reasons, it was not possible to stop the operation for emergency repairs. Subsequently, after research by the technical department, the oxygen-enriched combustion process was considered: under the same volume of acidic gas, increasing the oxygen content in the air required for combustion could reduce the amount of air needed. Thus, a temporary solution was devised – oxygen was injected at the inlet of the blower to increase the oxygen content in the air drawn in by the blower, allowing the facility to continue operating until scheduled maintenance could be carried out. Do you all think this method is feasible, and what are the things to keep in mind? http://down.hcbbs.cc/attachment/forum/201706/10/203353z7y06fdo70r6eod0.jpg Petrochemical area—New ideas for energy savings: the “Creative Ideas” campaign (the second phase is in full swing). https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1666758 (Source: Haichuan Chemical Industry Forum) 2017: “My Technical Upgrades” in the coal chemical industry. https://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Industry Forum website)
