Analyzer Systems in LNG Processing Plants

February 13, 2019 Process automation is a key issue in Liquefied Natural Gas (LNG) plants to ensure cost-efficient plant operation, high product quality, and process analytical systems deliver important data for plant control and operation. Gas Chromatographs are the typical type of process analyzers in LNG plants to make measurements for plant performance optimization and measurements of calorific value at many points throughout the process. GCs are complemented with online spectroscopy analyzers to provide continuous measurements of H2S and CO2 throughout the process as well.

FCCU - Environmental Compliance

November 21, 2017 Since the development and first commercial installation of a fluid catalytic cracking process unit in 1942, it has become a widely used and important process in refineries across the world. FCC Units are responsible for producing a large volume of high quality gasoline blending stock throughout the refining industry. With the Increasingly demanding environmental regulations, many FCC Units are requiring upgrades/modifications. Our custom-designed, analytical system is compliant with NSPS Subpart Ja requirements for daily calibration drift checks, quarterly cylinder gas audits and annual relative accuracy test audits; can continuously draw process gas into the system while effectively keeping particulate out of the analyzers; accurately measures CO, CO2, and O2 in order to calculate the rate of coke burn-off from the catalyst; and offers easy access for online maintenance and troubleshooting

Moisture in Liquid Hydrocarbons - Dryer Efficiency Solutions

September 1, 2017 Moisture in Hydrocarbons are a crucial measurement for many Dryer and Blending applications/processes. This can include anything from Butane, Propane, Diesel, and other additional streams. The measurement is not only a vital process control measurement, but is required for custody transfer applications. Our designs ensure that the Hydrocarbon Dewpoint for all/any streams are considered and facilitated to guarantee a quality, repeatable, representative analysis no matter what analytical device is utilized. Check out our Literature page to learn more or give us a call at 800.505.4122.
