Total Sulfur in Fatty Acids and Waste Vegetable Oils by TS 7000 Compliant to ASTM D5453

Oil refinery and clouds in sky.

Sulfur content in vegetable oils, animal fats, and waste vegetable oils varied greatly among these samples. Oil seeds can contain sulfur as high as a few thousand ppm.

In many countries the sulfur content standard allows maximum levels to be 10 or 15 ppm in automotive fuels, which includes biodiesel. It is known that when animal fats and waste vegetable oils are used for biodiesel production, the sulfur content is expected to be high, due to the presence of sulfur-containing compounds such as proteins. In addition to this, water-washing of the biodiesel may be a critical step for sulfur removal to obtain a good fuel quality biodiesel which does meet the respective allowable sulfur limit. This application note described the analysis and sulfur content in set of undiluted fatty acids which contains partly waste vegetable oils with low and high ppm sulfur content. With use of the TSHR TS 7000 model equipped with heated autosampler tray to maintain the sample in liquid form, this configuration enables customers to analyze the samples fully automatic in compliance to ASTM D5453 method.
