Background
Quick on-site analyzing the Sulphur content of fuel oil on-board a ship with minimum operation is essential for the shipowners and operators to comply with the latest IMO(MARPOL) regulations.
The IMO(International Maritime Organization) continuously sets new standards to minimize and control the harmful polluting exhausts from vessel engines. IMO is the World's largest maritime organization with over 170 member states and acts as a regulatory agency for the international maritime industry.
These regulations are enforced both globally and locally by each country and failure to comply can lead to heavy penalties.
Based on standard method such as ASTM D4294 and ISO 8754, XRF spectrometer is one of the most effective technology of establishing fuel compliance with the Sulphur and other elements regulations.
It will be essential and compulsory for each vessel to comply with the Sulphur limits of 0. 10%m/m in SECAs or 0.50% m/m in all other areas worldwide.
Meanwhile other similar sulfur control is widely applied, for example In India, all automotive diesel and gasoline was transitioned to Bharat IV with a 50 ppm maximum sulfur in April 2017.
Maximum permissible level of sulfur in fuel in Europe for 2003/17/EC (or EURO VI) directive requires a maximum amount of sulfur in fuel of 10 ppm.
Aviation Turbine Fuels specifications such as ASTM D1655 and D6615 require a maximum sulfur of 3000 ppm.
Introduction
The PS-4294 Energy-Dispersive X-Ray Fluorescence(EDXRF) systems was especially designed for on-board total sulfur content analysis in wide concentration range from ppm to percent levels. The portable compact design with low detection limits and high accuracy makes the PS-4294 the ideal tool for sulfur testing at sea, offshore or on land.
Features and Benefits
l Portable, rugged, compact design for total non-destructive sulfur analysis
l Quick analysis in 130 seconds per sample with minimum sample preparation
l User-friendly software and One-touch measurement start for testing
l Training for routine analysis takes only minutes
l Low cost of daily analysis without any gas consume
l Built for tough environments
l Intuitive interface displayed on the large 8 inches touchscreen
l Low cost of maintenance
