Determination of Sulfur in Ethanol samples using TSHR 7000 Series Analyzer according to ASTM D5453
Over the recent years, there have been major advancements in the development of biofuel diesel and gasoline. The use of sugars and other plant materials to manufacture alcohols as 100% fuels or as extenders to produce bio-gasoline has been around and actively applied in a number of countries globally. There were regionalized programs started to make bio-gasoline available. This has resulted in a large number of investments in bio-ethanol plant production. Elemental analysis is required to control fuel quality and show compliance with actual specifications. For ethanol and methanol fuel, ASTM, amongst others, has published sulfur content specifications which are laid down in ASTM D5453 method [1].
This application note describes the direct analysis for the routine measurement of Total Sulfur content in ethanol blends. The TSHR TS 7000 model Total Sulfur combustion analyzer fitted with the TSHR HR 7000 model autosampler was used to measure the Total Sulfur (TS) content in a set of ASTM Crosscheck ethanol (EtOH) samples. Sulfur detection was conducted using high temperature combustion connected to ultraviolet fluorescence detection in accordance with ASTM D5453. The standard test method ASTM D5453 is applicable to hydrocarbons with a sulfur content of 1 – 8000 mg/kg, boiling in the approximate range of 25 – 400 oC and with approximate viscosities between 0.2 – 20 cSt. The results obtained in this application note were compared with results obtained from ASTM Crosscheck Programs.
