Benfield solution monitoring made easy

Benfield solution monitoring made easy

Benfield solution monitoring Through the Benfield process, vanadium is used to assist in the removal of CO2 and sulphur. As part of this process, Va5+ is reduced to Va4+. By monitoring this ratio, it is possible to maximise the use of the Benfield solution without endangering the removal process by...

NIR spectroscopy in the polymer industry

NIR spectroscopy in the polymer industry

Due to NIR analysis requiring no sample preparation and being non-destructive, many polymer and plastic attributes can be measured rapidly inline, online, atline or offline for qualitative as well as quantitative parameters. NIR spectroscopy in the polymer industry In this application bulletin we presents some examples of NIR applications and...

Control your catalysis with DIA

Control your catalysis with DIA

Quality control of catalysts with the Camsizer P4 from Retsch Technology The analysis of size and shape plays an important role for the quality control of catalysts. Sieve analysis is often used for this, however, it only provides the required size information for spherical particles. Rods, for example, pass the mesh with a particular orientation which makes...

ASTM method D8045 beats ASTM D664

The new ASTM method D8045 demonstrates the superiority of thermometric titration for complex petroleum samples, as it provides for better reproducibility of results, is significantly faster, and consumes less reagent than the commonly used method D664. This method requires no sensor maintenance aside from a solvent rinse, needs no hydration...

Metrohm: Coulometric Karl Fischer Titration for ASTM D6304

Water occurs as a contaminant in virtually all petroleum products. It reduces lubricant properties, promotes micro­bial oil degradation, leads to sludge formation in the tank, and promotes corrosion of ferrous and nonferrous metals. While at higher temperatures water boils and contributes to a partial degreasing, temperatures below freezing point lead...

Metrohm IC: Determination of various amines in refineries via IC

Optimised separation on wide range in combination with alkaline and alkaline earth metals. Petroleum and natural gas products can contain acid gases such as hydrogen sulfide and carbon dioxide resulting in a “sour” product. These acid gases are corrosive and undesirable in final gas products. Alkanolamines are used in refineries...
