THE IMPORTANCE OF ACCURATE ETHANOL TESTING & INTRODUCTION TO THE WI INSTRUMENTS MODEL E
Ethanol has emerged as a crucial renewable fuel source in the energy sector. It is blended with gasoline in varying concentrations, commonly E10 (10% ethanol, 90% gasoline) and even in higher blends such as E85 (85% ethanol, 15% gasoline). USA’s ASTM D4806, D5798, and D7794, Brazil’s ANP Resolution n° 19, EU’s prEN 15376 and others require that ethanol, water and methanol concentrations are measured for the ethanol product and in the fi nal product of fuel ethanol, denaturant concentration should also be measured. Hence, to ensure that ethanol used in the sector meets stringent quality, safety, and performance standards, comprehensive ethanol testing is essential.
Measuring ethanol for purity, water content, and the presence of contaminants is critical. Contaminants can cause corrosion of metal parts, swelling of some elastomers, reduce fuel effi ciency, and damage engines. Water can also cause phase separation in ethanol and gasoline blends, which can result in a layer that cannot combust and another lower octane number layer that causes knocking in the engine. Testing ethanol helps to maintain the integrity of the fuel supply and protects engine components from damage.
The Role of WI Instruments Model E in Ethanol Testing
WI Instruments (WI), a new brand under CFR Engines, provides precise testing solutions for the energy sector, particularly in fuel ethanol and ethanol testing. The company has developed Model E to meet the rigorous demands of ethanol production, fuel ethanol blending, storage and distribution by measuring quickly in real-time ethanol, denaturant, methanol, water, and isopropanol concentrations, and density.
The Model E has been deployed globally and tested in three different continents. Across the different samples, lab conditions and environments, it has been able to achieve the following testing results and accuracies of ethanol concentrations.
effi ciency, reducing the time and cost associated with ethanol testing. Due to our proprietary semiconductor technologies, a minimum sample volume of 3mL is suffi cient to perform measurement. Our IP also enables a robust and light design for minimal maintenance, further enhancing cost-effectiveness.
4. Real-Time Monitoring and Quality Control: WI solutions can enable real-time monitoring of ethanol and other components non-destructively during the fi nal production and blending processes, allowing for immediate adjustments and reducing the risk of contamination or substandard fuel from reaching the market.
5. Reduced Product Giveaway: With enhanced accuracy, WI solutions can provide blends even more fi nely to achieve more savings with reduced product giveaway.
WI Instruments Core Technologies
Our product is designed internally starting from the semiconductor chips all the way to the circuits, the mechanical parts and the algorithms.
