METHOD FOR MEASURING ODOR LEVEL IN NATURAL GAS

摘要

A method and apparatus which is particularly applicable to directly and objectively measure odor level in natural gas. The apparatus responds selectively to sulfur compounds in natural gas and produces an output signal proportional to the odor level of the gas, in the same manner as an "average" nose. A set of odor intensity factors developed empirically are applied to the output signal to provide a numerical value which expresses odor intensity of the gas in terms of a reference odorant compound.
