Little bit of information about light hydrocarbons here…

The petrochemical industry performs many tests for refined products. Refineries, Inspection and Chemical labs across the world use ASTM, ISO, IP, and other accepted chemical industry standards and protocols. Materials tested include the entire complex range of hydrocarbon based chemicals derived from petroleum. This also applies to primary petrochemicals including olefins, aromatics, and synthesis gas. Petrochemical testing can extend to trace and ultra-trace level analysis. Chemical testing expertise includes purity & component, trace composition, trace contamination, quality control, troubleshooting, and other chemical analysis expertise. ASTM chemical testing methods are utilized by laboratories for chemical analysis of petrochemicals, compounds, materials, petroleum, fuels, consumer products, and other chemical substances. ASTM chemical test methods are industry accepted standards for quality control and reliability. Testing measures require trace analysis to ppm, ppb, and ppt levels. Petrochemicals and chemicals are tested for quality control, purity, contamination, research and development, troubleshooting, environmental evaluation, regulatory compliance, and more.

The Total Sulfur content in automotive fuels is a key parameter when undertaking process/quality control analyses and for ensuring compositional specifications in finished refinery products are met. Sulfur components in process feeds may damage the catalyst performance in refinery processes, so lowering the refinery efficiency and profitability. Additionally, the Total Sulfur content in products like automotive fuels is subjected to restrictions by regional and international regulations, such as the Tier 3 program, and must therefore be monitored using reliable methods and instrumentation. The American Standardization of Testing Methods (ASTM) published the ASTM D5453 method specifically for the petroleum industry, covering the determination of the total sulfur content in liquid petroleum products by ultraviolet fluorescence detection.

Working range Total Sulfur: 1.0 – 8,000 mg/kg
Boiling range: 25 – 400 °C
Viscosities of samples: 0.2 – 20 cSt (mm2/s) at room temperature
Sample types: Naphthas, Distillates, Engine Oil, Ethanol, Fatty Acid Methyl Ester (FAME); Engine Fuel such as Gasoline, Oxygen Enriched Gasoline (Ethanol Blends, E-85, M-85, RFG), Diesel, Biodiesel, Diesel/Biodiesel Blends, Jet Fuel

EST analytical solution:
EST analytical offers the TS NexiS and TS 7000 series models and combined instrument configurations like TN/TS NexiS and TN/TS 7000 models with semi-automatic syringe or fully automatic liquids injection through HR 7000 models Liquids Autosampler configurations. The use of boat inlet technique for the NexiS models is recommended when analyzing high boiling point and viscous samples.

Some process catalysts used in petroleum and chemical refining may be poisoned when even trace amounts of nitrogenous materials are contained in the feedstocks. This test method can be used to determine bound nitrogen in process feeds and may also be used to control nitrogen compounds in finished products.

Working range Total Sulfur: 0.3 – 100 mg/kg
Boiling range: 25 – 400 °C
Viscosities of samples: 0.2 – 20 cSt (mm2/s) at room temperature
Sample types: Naphthas, Distillates, Oils

Many type of Nitrogen compounds can contaminate refinery catalysts and tend to be the most difficult class of compounds to hydrogenate. The Nitrogen content remaining in the product of a hydrotreator is a critical measure of the effectiveness of the hydrotreating process. In lubricating oils the concentration of Nitrogen is a measure of the presence of Nitrogen containing additives. This test method is intended for use in production plant control (QC) and in research applications.

This test method covers the determination of Nitrogen in liquid hydrocarbons, including petroleum process streams and lubricating oils in the concentration range from 40 mg/kg to 10,000 mg/kg Nitrogen. For light hydrocarbons containing less than 100 mg/kg Nitrogen, ASTM D4629 can be more appropriate.

Working range Total Nitrogen : 40 – 10,000 mg/kg
Sample types: Lubricating Oils, Liquid Hydrocarbons
