Apparatus for continuously measuring the concentration of a gas-mixture component

Claim 1

APPARATUS FOR MEASURING IN A FLOW OF A GAS MIXTURE THE CONCENTRATION OF A COMPONENT GAS SUBSTANTIALLY COMPLETELY SOLUBLE IN CONDENSING STEAM, BY CONTACTING THE FLOWING GAS MIXTURE WITH A CURRENT OF CONDENSING WATER VAPOR AND MEASURING THE QUANTITY OF COMPONENT GAS SUBSTANTIALLY COMPLETELY DISSOLVED IN THE CONDENSATE CURRENT, COMPRISING A GAS INLET FOR THE GAS MIXTUR, A COOLER AND A VESSEL WITH HEATING MEANS, ALL CONNECTED IN SERIAL RELATION TO FORM A CONTINUOUS GAS FLOW PATH, AND A PUMP IN SAID PATH FOR PASSING THE GAS MIXTURE THROUGH SAID COOLER INTO SAID VESSEL; WATER SUPPLY MEANS COMMUNICATING WITH SAID VESSEL FOR PASSING A CONSTANT FLOW OF WATER INTO SAID VESSEL HEATABLE BY SAID HEATING MEANS TO A TEMPERATURE AT WHICH THE WATER IS EVAPORATED, MEANS CONNECTED WITH SAID VESSEL FOR CONDENSING SAID EVAPORATED WATER WHEREBY SAID COMPONENT OF THE GAS MIXTURE BECOMES SUBSTANTIALLY COMPLETELY DISSOLVED IN THE CONDENSING WATER VAPOR, SAID VESSEL HAVING A COLLECTING SPACE FOR THE RESULTING SOLUTION; SAID GAS FLOW PATH COMPRISING A GAS OUTLET DUCT MEANS FOR PASSING THE RESIDUAL AMOUNT OF THE GAS MIXTURE OUT OF SAID VESSEL; A DRAINAGE PASSAGE COMMUNICATING WITH SAID COLLECTING SPACE FOR CONTINUOUSLY REMOVING A FLOW OF SAID SOLUTION FROM SAID VESSEL; AND MEANS FOR MEASURING THE CONCENTRATION OF THE DISSOLVED COMPONENT IN SAID PASSAGE.
