Total Sulfur and Total Nitrogen in Fuels and Chemical

Total Sulfur and Total Nitrogen in Fuels and Chemicals

Regulatory agencies around the world have been implementing increasingly stricter fuel emissions guidelines over the past decades to limit air pollution. Regulations such as the American Tier III, European Euro 6 or the Indian Bharat VI set quantitative limits on the permissible number of specific pollutants that can be released during combustion.

Sulfur and Nitrogen are both controlled under these regulations due to the health and environmental impact of their oxides: Sulfur Dioxide (SO2), Nitrogen Oxide (NO) and Nitrogen Dioxide (NO2), commonly referred to as NOx. In order to measure sulfur and nitrogen content in fuels, chemicals and petrochemicals, Process Insights designed the ATOM Instrument XT-2000 laboratory analyzer for both Total Sulfur (TS) and Total Nitrogen (TN) measurements.

The XT-2000 utilizes patented Excimer UV Fluorescence (EUVF) Technology for TS measurement and proprietary Chemiluminescence (CL) technology for TN measurement offering exceptional sensitivity that does not require a vacuum pump minimizing maintenance requirements and improving analytical stability. The XT-2000 provides accurate, precise and fast analysis for a broad range of samples with a typical analysis time of 3 minutes or less.

The XT-2000 demonstrates outstanding linearity for 0-100 ng/μL TS/TN in isooctane standards with excellent 0.9998 and 0.9995 correlation for both TS and TN measurements. Results for various fuels and chemicals presented on the following page show TS and TN content from ppb level to 31.45 ppm/wt (TS) / 12.48 ppm/wt (TN). All samples were analyzed 5 times with an RSD of 2% or better for samples above 1 ppm.

Trace Sulfur in Butane and Other Gas or LNG Applications

Trace Sulfur in Butane and Other Gas or LNG Applications

Driven by an increasing need for Total Sulfur trace analysis in gas and LNG products, Process Insights developed the ATOM Instrument TraceS-1000.

This remarkable online process analyzer incorporates our patented Excimer UV Fluorescence (EUVF) Technology and is specifically designed for measurement of Trace Total Sulfur content in applications that require the ultimate in low-level sensitivity, such as polymer-related applications.

One application where the TraceS-1000 has demonstrated exceptional analytical performance is the measurement of total sulfur in butane at the ultra-low range of 0-1000 ppb/vol.  Acquired test results reflect excellent linearity, precision and long-term stability for this extremely low range. Analytical results represented were obtained utilizing an oxygen/argon blend for combustion.

The TraceS-1000 provides unparalleled sensitivity and rapid response to concentration changes with a typical analysis time of only 180 seconds. Instrument operation is simplified with intuitive and user-friendly software, with an added feature that allows data averaging for enhanced analytical precision. Eight-hour repeatability using a sulfur dioxide (SO2) permeation tube for sulfur addition to instrument-grade butane demonstrated a SD of 14.7 ppb at 205 ppb/vol. concentration or 7.17% RSD. Using the moving average feature, a 3-run analysis (9-min. response time) further improved repeatability, yielding a SD of 8.5 ppb or 4.16%. Various concentrations run for linearity characterization reflect rapid response, outstanding repeatability and excellent linearity with a 0.9965 correlation.
