Pyro-Electrochemical On-Line Ultra Low Sulfur Analyzer

Abstract

Current and upcoming regulations worldwide require maximum concentrations of sulfur in fuels to be in the range 10–50 mg/kg. This paper describes a new on-line analyzer for ultra low sulfur, the first to employ “Pyro-electrochemical” technology, which is significantly simpler than other pyrolysis methods such as Pyro-microcoulometry and Pyro-UV fluorescence.

The technology is based on ASTM D 6920. The instrument is described with special reference to the modifications needed to adapt the technique to on-line analysis. Experimental results are given for long term stability, sensitivity, precision, speed and linearity of response, temperature stability, and sensitivity to nitrogen.

Keywords:
ultra low sulfur, fuels, on-line process analyzers, thermal oxidation, pyrolysis, electrochemical sensors, nitrogen converters
