Abstract
Section titled âAbstractâProblems related to the presence of elemental sulfur (S 0 ) in natural gas have occurred frequently in several countries.The presence of these contaminants has caused failures in the natural gas distribution system causing mostly sulfur deposition in pipelines, control valves and turbine thermal power, which leads to clogging of nozzles, control valves and problem in the control systems.These events have been reported more frequently by carriers and natural gas distributors with the increase in the consumption of fuel.To perform the S 0 detection in natural gas, either directly in the gaseous matrix or after cleaning a certain amount of natural gas with organic solvents it was developed an electrochemical sensor boron doped diamond.This sensor was chosen for its wide potential window in both aqueous and organic solutions, low background current, chemical and mechanical stability, and low adsorption S 0 on the electrode surface.The method validated to detect S 0 in organic solvent using the sensor diamond doped with boron had a detection limit of 0.8 mg L -1 .
