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...

OFCEAS or Optical Feedback Cavity Enhanced Absorption Spectroscopy, is a gas analysis technology developed by the University Joseph Fourier. OFCEAS essentially differs from the older technology enhanced-cavity TDLAS by its feedback principle: a part of the emitted radiation is returned from the chamber to the laser, enabling the tuning of the laser and the cavity, creating a resonance phenomenon. The measuring cavity in which the sample is analyzed is equipped with high reflectivity mirrors (...

Phosphorous, sulfur and chlorine are commonly analyzed elements in liquids such as petroleum products and organic solvents. For example, phosphorous is added to lubricating oils to prevent wear of gears under high pressure. Sulfur content in automotive fuel oils are regulated by the US environmental protection agency (EPA) and directives such as EURO VI to minimize air pollution due to automotive vehicles. Chlorine, contained for example in crude oil, is an unwanted element known for corrodin...

Oil industry started long before 1900 and is older than gas chromatography, so test distillation was used for sample analysis and not GC. Fast GC analysis of Diesel and Jetfuel already is a standard but Gasoline is not. Detailed hydrocarbon analysis (DHA) with pattern recognition uses GC analysis input to separate and identify gasoline and blendfeed compounds in 6 minutes. The composite report of DHA is input for the fugacity filmmodel of ASTM method D86 distillation. GC post-run software all...

Comprehensive two-dimensional gas chromatography (GCxGC) has been proven to be an ideal platform for the analysis of complex mixtures, but the data processing aspect has a reputation as being difficult and time-consuming. GCxGC data exploration, filtering and mining need not be complex, and can be implemented in an environment that is based on classical peak detection algorithms and chromatographic rules. Here we will demonstrate simple yet effective GCxGC data processing for a range of...

Fugitive hydrocarbon emissions cost the energy sector $5B per year, account for 12% of greenhouse gas emissions and jeopardize safety and public health. Current gas monitoring methods lack the ability to take measurements in moderate winds, at varying heights and to provide simultaneous measurements of a diverse range of hydrocarbon species. The most advanced technique for remote emission measurements is differential absorption lidar (DIAL), in which intense IR pulses are fired into the atmos...

Ultrahigh performance supercritical fluid chromatography (UHPSFC) coupled with mass spectrometry (MS) provides an agile and robust analytical platform to meet the challenge of analysis of complex petrochemical material. The selectivity afforded by the different SFC column technologies, mobiles phase and atmospheric pressure ionisation techniques provides approaches to reveal specific chemistries within the sample, with the added benefit of sample compatibility with the solvents used. The tech...

Non-traditional gasoline additives (NTGAs) like ethyl acetate are being researched as beneficial octane-booster replacements for ethanol and methyl tert-butyl ether. Other octane-enhancing NTGAs, including acetone and N-methylaniline which can degrade automobile engine performance, are sometimes used illegally in gasolines outside the United States and Europe. Unfortunately, monitoring programs relying on ASTM D6730 (Detailed Hydrocarbon Analysis) and ASTM 6839 (Multidimensional Gas Chromatog...

Today's quality control labs face high regulatory and financial pressures. International and national regulations (e.g. ASTM D6667, D5453, D5762, D7457 etc.), set high standards for the labs and especially in industry and contract labs - analysis has to be affordable in order to keep a competitive pricing for final products and offered services. Additionally, complex sample matrices make even routine S/N/Cl/C determinations difficult and the amount of samples that have to be analyzed in th...

The Methane Number (MN) is a measure of the resistance of fuel gases to engine knock. The MN can be described on an engine by comparing the fuel to pure methane, which has an MN of one hundred and pure hydrogen which has a MN of zero. Several models and calculators have been developed to calculate an estimated me MN based on a thorough compositional analysis. Operators of large scale gas engines can improve efficiency and reduce maintenance by tuning and operating engines under optimum con...
