SO3 Monitor

OPERATING PRINCIPLE

The SO3 or H2SO4 in the gas sample is absorbed as sulphate ions (SO42-) in an aqueous solution of propan-2-ol in water.

The solution is passed through a bed of barium chloranilate. The acid chloranilate ions created are measured in a continuous

flow photometer. By maintaining a constant ratio of flow rates for the gas and the propan-2-ol absorbing solution,

the concentration of acid chloranilate ions can be directly related to the sulphate ion concentration in the absorbing solution,

and hence the SO3 concentration in the gas.
