Porla Analyzer for the Maritime Industry
Auramarine Porla fuel stability and compatibility analyser for heavy fuel oil and crude oils
Auramarine’s Porla analyser is an easy, reliable and fast analysis instrument that improves profitability of refinery processes by enabling refineries to select more economic mixtures of crude oils with no risk of fouling problems. Auramarine’s Porla analyser enables prediction of compatible blending ratios between different oils by measuring their blending compatibility parameters. Unlike other comparable analysers, Porla analyser is capable of measuring stability and compatibility parameters of oils that have a very low asphaltene content (down to 0.05 %). It complies fully with ASTM standard D7112.
Methods: ASTM D7112

- The system enables proactive testing of fuel compatibility
- Determination of stability and compatibility parameters In (insolubility number) and Sbn (solubility blending number)
- ASTM test method D7112 since 2005
- Ability to use different paraffinic and aromatic solvent combinations, designed for testing fuel combinations where at least one of the fuels must contain asphaltenes.
- The system will self-clean at the end of each test procedure
- With Auramarine Porla analyser, you can minimise the often manual sludge and tank cleaning and maintenance work. You can also reduce the amount of sludge and subsequently the sludge disposal costs at shore reception facilities.
- Testing and knowing your fuels helps to avoid fuel supply disturbancies or engine failures (or in worst case loss of propulsion). The combustion can be compromised due to e.g. excessive fouling of cylinders and differential thermal loadings on the cylinders or separator or filter disturbancies. Trouble-free combustion can help to avoid off-duty losses and port fees caused by fuel system or engine downtime.
- With less fuel going to sludge, the fuel is used efficiently which translates into cost savings and indicates the vessel’s CII calculation.
