Abstract
For the desulfurization of carbon dioxide, catalytic oxidation process was found very useful.In the 1st report catalysts and oxidation conditions were present-ed, and in the 2nd report purification of oxidzed gas and recovery of SO2 were describ-ed
In this report corrosion data on fabricating material and operation data of actual unit are reported.
Author designed and constructed a plant having the capacity of 5, 000Nm3/hr, and has put it into successful operation.For example, 4, 000Nm3/hr raw CO2 from hot carbonate and MEA unit having the following composition, CO2 97.7%, H2S 1.2%, O2 0.1%, CO 0.1%, H2 0.9% and Org.S 5Smg/m3, was desulfurized by this process, and the composition of the desulfurized CO2 was as follows, CO2 99.2%, O2 0.1-0.2%, CO 0.1%, H2 0.5%, H3S 2-3mg/m3, Org.S 7-15Smg/m3 and SO2 0.1mg/m3>.
