During start-up and shut-down, any time a sulfur recovery unit (SRU) transitions from ambient temperature through fuel gas warm up to the introduction of acid gas, measurement of 02 stoichiometry is critical. Historically, operators have manually taken samples using a portable electrochemical type Os analyzer. While giving more or less satisfactory results, the requirement for more stringent ...

ABSTRACT Preventing condensation within gas samples is important if accurate measurement of a soluble component is required - principally nitrogen dioxide within combustion products. Maintaining gas samples above the water or acid dew point is normally achieved by heating the sample transfer lines and gas analyser modules. This paper presents simple methods for the dew point ...

In order to determine volatile fatty acids (short chain monocarboxylic acids with 2 to 6 carbon atoms in a molecule) in leachates formed in organic waste piles a procedure based on static headspace (HS) coupled with gas chromatography (GC) have been proposed and optimized. The conditions of HS extraction and sample introduction into a gas chromatograph as well as of chromatographic separation ...
