Sulfur dioxide measurement system
Abstract
Abstract A QUANTITATIVE DETERMINATION OF RELATIVELY SMALL OR TRACE AMOUNTS OF GASEOUS SULFUR DIOXIDE INVOLVES A REACTION BETWEEN MERCUROUS CHLORIDE AND SULFUROUS ACID, THE LATTER FOAMED WHEN SULFUR DIOXIDE IS DISSOLVED IN WATER. ONE OF THE REACTION PRODUCTS IS A WATER SOLUBLE BIS-SULFITOMERCURATE COMPLEX, THE MERCURATE BEING EASILY REMOVABLE FROM THE REMAINDER OF THE REACTION MIXTURE. THE CONVERSION OF SULFUR DIOXIDE TO THE BIS-SULFITOMERCURATE COMPLEX IS ABOUT 95% COMPLETE. BY NUCLEONICALLY DETECTING THE AMOUNT OF THE BIS-SULFITOMERCURATE COMPLEX, WHICH CONTAINS A METAL HAVING A HIGH Z NUMBER (ATOMIC NUMBER), USING A MONOENERGETIC SOURCE OF NUCLEAR RADIATION IN THE RANGE OF 15 TO 25 KEV., THE AMOUNT OF THE COMPLEX IS DETERMINABLE AND EASILY COMPARED AGAINST A KNOWN STANDARD SAMPLE EITHER ELECTRONICALLY OR VISUALLY. THE PRESENT SYSTEM MAY BE USED ON A CONTINUOUSLY FLOWING GAS SUCH AS STACK GAS, IN WHICH EVENT IT IS UNNECESSARY TO SCRUB THE GAS, AND PERMITTING ACCURATE DETERMINATION OF TRACE AMOUNTS OF SULFUR DIOXIDE BY MONITORING OR CONTROLLING THE GAS FLOW RATE.
