  • Color Detection in LNG (Transporation)

    Given the large volumes of LNG under transport, ROI on real-time measurement systems such as our GUIDED WAVE™ ClearView® db Dual Beam Photometer can be measured in days. LNG is natural gas cooled to a liquid state. Natural Gas is composed primarily of methane, but may also contain propane, ethane, and other heavier hydrocarbons as well as small residual quantities of N2, O2, CO2, H2O, and some sulfur containing compounds.

    Prior to liquefaction these residual materials are removed with only clean hydrocarbons remaining. The composition of natural gas can vary slightly from different producing locations. Typically, LNG is a   colorless material, but during distillation the carryover of larger hydrocarbons (C6+) can affect the color of the LNG (typical specification for C6+ in LNG is 0 to 0.05%).

    Our GUIDED WAVE™ Saybolt Color Analyzer is a complete solution that provides accurate, real-time, reliable results. The analyzer employs a dual-beam design – meaning; the system has a continual internal optical reference check that allows it to self-compensate for signal variation due to non-sample conditions. This technology provides long term stable readings offering laboratory grade results from a process analyzer. It consistently measures the color variation without interference from other factors.

  • Color Levels in LNG

    Inbound LNG product is maintained at a different specification than the outbound/exported LNG product. Color analysis is necessary for both the in and outbound LNG product because in each case, the customer requires a high degree of accuracy and repeatability that is reliable and consistent to third party standards.  Customers are looking for an analyzer to measure the Saybolt color of the LNG flowing in their pipeline.

    By using a GUIDED WAVE™ Saybolt Color Analyzer System, the customer was able to accurately measure this color change with repeatable values. Our GUIDED WAVE Color Systems provide a complete ready-to-go solution which included a 50 mm pathlength SST probe, fiber optic cables for remote processing, control software and Saybolt application calibration. The analytical calculations are all encoded in the software so answers and alarms are clearly reported.

    Flue gas desulfurization is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants. The process of FGD was designed to absorb the sulfur dioxide in the flue gas before it is released. This is accomplished through either a wet or a dry process. There are many methods for removing sulfur dioxide from boiler and furnace exhaust gases. The steam generators in large power plants and the process furnaces in large refineries, petrochemical and chemical plants, and incinerators burn considerable amounts of fossil fuels.  The flue gas desulfurization system plays an important role in addressing the sulfur dioxide pollution in many industries.

    Monitoring flue gas desulfurization is crucial to effectively remove sulfur dioxide (SO2) from the exhaust flue gases of fossil-fuel power plants. SO2 is a harmful pollutant that contributes to acid rain, smog formation, and adverse health effects. flue gas desulfurization systems employ various methods, such as wet scrubbing or dry sorbent injection, to capture and remove SO2 before it is released into the atmosphere. Monitoring flue gas desulfurization performance ensures that the desired level of SO2 removal is achieved and maintained consistently. By monitoring parameters such as SO2 concentrations before and after flue gas desulfurization, temperature, pressure, pH, and reagent consumption, operators can assess the efficiency of the desulfurization process, troubleshoot any issues, and optimize the system’s operation. Accurate flue gas desulfurization monitoring helps power plants comply with emission regulations, minimize environmental impacts, protect human health, and ensure sustainable and responsible operation of fossil-fuel power plants.
