PROCESS FOR MONITORING THE PRESENCE OF SO3, H2SO4 IN EXHAUST GASES CONTAINING SO2

摘要

A.PROCESS FOR MONITORING THE PRESENCE AND MEASURING THE SO 2, SO 2 CONTENT IN A SURVEYED GASEOUS ENVIRONMENT ALSO CONTAINING HO AND SO. / P P B.ON MAKES A FIRST MEASUREMENT OF THE CONTENT COMBINED IN SO AND SO OF A SAMPLE OF GAS, SEPARATED SO OF THIS SAMPLE AND SO AND HSO, BY COOLING THE SAMPLE AT A DETERMINED TEMPERATURE WHICH IS SUFFICIENT TO CONDENSE SO IN THE PRESENCE OF H0 AND HSO BUT WHICH IS NOT NOT SUFFICIENT TO CAUSE CONDENSATION OF SO, PROCESS, AFTER THIS SEPARATION STEP, TO A SECOND MEASURE THAT GIVES ONLY THE CONTENT OF THE SOIL SAMPLE, AND FINALLY DETERMINES THE CONTENT IN SO, HSO OF GAS EXAMINED BASED ON THE DIFFERENCE BETWEEN THE FIRST MEASUREMENT OF THE COMBINATION SO AND SO, HSO AND THE SECOND MEASURE GIVING THE SO 2 CONTENT FOLLOWING THE SEPARATION STEP.
