Partial Oxidation (POX) Reactions Pose Challenges for Thermocouples and Other Measuring Instruments
Alina Green | Applications, TemperatureThe extreme temperatures and high concentration of hydrogen in partial oxidation (POX) reactors create a harsh environment for measuring instruments that are not equipped to handle such challenges. Partial oxidation (POX), the initial process of turning crude …
Pyrometer or Surface Thermocouples: Which Is Better for Tube Wall Temperature Monitoring?
Alina Green | Know-how, TemperatureOperators of steam methane reformers have various methods at their disposal for measuring tube wall temperature, but the best solution for accurate and continuous temperature measurement are surface thermocouples. The furnace tubes of a steam methane reformer (SMR) …
Venturi Nozzles Improve Flow Distribution, Reduce Uneven Coking During Ethylene Production
Alina Green | Applications, FlowVenturi nozzles help regulate feedstock flow rates in order to minimize uneven coking inside the radiant tube walls of furnaces. Along with tubeskin thermocouple assemblies, Venturi nozzles enable ethylene crackers to operate more efficiently. Refineries and …
Reasons for Choosing a Liquid-Filled Industrial Pressure Gauge
Hardy Orzikowski | Know-how, PressureLiquid-filled gauges surpass dry gauges for two main reasons: performance and extended service life. Pressure gauges that are filled with a liquid, usually glycerin or silicone oil, perform better in less-than-ideal conditions. They are also more economical in the long …
