| 20110217787 | CONCENTRATION MEASURING APPARATUS FOR HYDROGEN SULFIDE IN GAS FLOW, AND METHOD FOR DETERMINING SULFIDE ION - A concentration measuring apparatus for hydrogen sulfide includes an absorbing liquid that can absorb gaseous hydrogen sulfide as sulfide ion; a hollow fiber membrane contactor that contacts a gas flow with a flow of the absorbing liquid through a membrane, so that the absorbing liquid absorbs gaseous hydrogen sulfide in the gas flow as sulfide ion; a pump for a first channel that feeds the absorbing liquid to the hollow fiber membrane contactor; an oxidizer that exothermically reacts with sulfide ion; a pump for a second channel that feeds the oxidizer to the absorbing liquid; a first thermometer that measures a temperature of the absorbing liquid before the sulfide ion that the absorbing liquid has absorbed exothermically reacts with the oxidizer; and a second thermometer that measures the temperature of the absorbing liquid after the sulfide ion that the absorbing liquid has absorbed exothermically reacts with the oxidizer. | 09-08-2011 |
