Biofuels, mainly derived from vegetable oils or the fermentation of plant material, have gained importance over the last few decades as more sustainable and environmentally friendly alternatives to fossil fuels. However, the production of raw materials for biofuel production has led to significant deforestation and competition for agricultural farmland with traditional crops used as staple food for humans and animals. To mitigate effects, new sources like algae have been developed for biofuel...

At our recent Air Quality and Emissions event, Dr. Lesley Sloss of the International Centre for Sustainable Carbon gave a 20-minute presentation outlining emerging approaches to the global challenge of monitoring mercuring. Dr. Sloss addresses: The global spread of mercury pollution Contemporary and historical regulation of mercury emissions Alternatives to direct, fleet-based monitoring Cutting-edge modelling software for the estimation of emissions

At our recent Air Quality and Emissions event, David Graham of Uniper gave a 30-minute presentation outlining current standards for the quality assurance of mercury around the globe. Mr. Graham discusses: The similarities and differences between quality assurance procedures in the United States and Europe Type-testing requirements and measurement uncertainty Alternatives to current conventions in performing linear calibration The most effective methods for performing certifi...

At our recent Air Quality and Emissions event, Dr. Johannes Pfingsten of VDZ gave a 10-minute presentation comparing methods for the monitoring of mercury emissions.   Dr. Pfingsten discusses: The advantages and disadvantages of the prevailing reference method, EN13211 Different methods for reducing the limit of quantification Prospects for the wider utilisation of sorbent-trap methods Controlling breakthrough at different concentrations

At our recent Air Quality and Emissions event, Shawn Wood of Ohio Lumex gave a 20-minute presentation comparing methods for the monitoring of mercury emissions.   Mr. Wood considers: The prospects of emerging sorbet-trap technologies A range of reliable means for cement and power plants to achieve compliance The state of plant regulation in the United States Notable emissions limits for power and cement plants

Crude oils contain as many as 45 elements, many of which can have adverse effects on petroleum refining and product quality. These effects can include poisoning of the catalysts used during the refining process or corrosion to the process equipment. The determination and quantification of these trace elements can be particularly challenging because of the high viscosity of many crudes and the presence of large particulates. This requires time-consuming sample preparation, such as ashing and w...

Karl Fischer titration is an analytical technique widely used by chemists throughout the petroleum related sector.  Many chemists will agree that accurate results are most important followed by delivering results quickly, consistently and safely.  Smooth transitions between testing runs is also highly desirable. There are a number different KF methods available to cover the spectrum of samples within the hydrocarbon markets.  This webinar will give insights into which methods are best e...

Be it turbines, heavy equipment, or any other kind of machinery - monitoring hydraulic and lube oils is critical for performance and to prevent premature wear. In this eLearning session we focus on titration, near-infrared spectroscopy and voltammetry and their potential to increase efficiency of oil condition monitoring. Utilizing these methods, critical chemical and physical parameters can be determined in large sample series completely unattended for faster analysis, higher throughput and...

Water content in lubricants and other petrochemical products is a critical parameter that has to be closely monitored in the manufacturing of such commodities and all along the value chain. The presence of moisture in fuel and lubricants promotes corrosion and engine wear negatively affecting performance and resulting in the plugging of filters. Moreover, moisture can impede the effect of additives and promote growth of deleterious bacterial organisms. Knowing about the water content helps...

Precision, accuracy and robustness are key words and essential parameters to determine the effectiveness of any analytical application. Surveyors, refinery, and QC labs must determine the Nitrogen and Sulfur content with fewer personnel while the number of samples keep increasing and the time to report is under pressure. Moreover, all these analyses must be done in compliance with a variety of test methods, such as the ASTM D5453, ASTMD4629 and ASTM D6667. All these factors are pressing on...
