  • Page 11: Overview

    Overview UOP CCR Platforming Process “The CCR Platforming process uses naphtha boiling in the range of 180–400 °F to produce high-octane gasoline or petrochemical precursors. This technology is the world’s leading reforming process. It is also the technology of choice for new reforming applications, providing refiners with proven, ultra-low-pressure (50 PSIG reactor pressure) operation and producing the highest reforming yields.

  • Page 14: About The Wdg-V Uop Analyzer

    About the WDG-V UOP Analyzer Designed for fast response in a wide range of flue gas applications, the analyz- er mounts directly on the combustion process to provide continuous measure- ment of oxygen. A sample is drawn from the process stream by means of an air-operated aspirator and is immediately returned to the process.

  • Page 15: Basic Elements Of The Analyzer

    Basic Elements of the Analyzer The WDG-V UOP analyzer is a complete standalone unit; no separate controller is required. The unit consists of three basic systems: • Plumbing Includes all inlet and outlet tubing, O Cell Housing, the calibration gas inlet and aspirator assembly, flow sensor, and the aspirator used to pull the sample into the analyzer.

  • Page 16: How The Oxygen Measuring Cell Works

    Cell indicates the oxygen content of the other gas. A reference gas, usually air (20.9 % O ), is used for one of the gases. Figure 1-1. Zirconium oxide Cell principle of operation. 1-6 | Thermox ® WDG-V UOP ATEX-IECEx Analyzer PN 9000-280-VE, Rev B...

  • Page 17: Measuring Non-Combustible Gases

    The voltage of the Cell depends on temperature, and so the Cell is maintained at a constant temperature. The oxygen content is then determined from the Nernst equation: where R and F are constants, T is absolute temperature, and O and O are the oxygen partial pressures on either side of the Cell.

  • Page 18: About The Analyzer Sample System

    About the Analyzer Sample System The WDG-V UOP was designed for meeting the purpose of low level oxygen measurement during the regeneration cycle in which coke deposits are re- moved from the catalyst by oxidation. The WDG-V UOP analyzer has a specially treated Zirconium Oxide Cell which is used to survive the destructive effects of halogen-oxidation.

  • Page 25: Unpacking And Inspecting The Equipment

    Unpacking and Inspecting the Equipment Remove any packing material from the WDG-V UOP Analyzer. Check for dam- age. If equipment is damaged, notify the carrier and contact AMETEK Service (https://www.ametekpi.com/customersupport/requestsupport) immediately if parts are missing or damage is found, and to verify if damaged parts will require replacement prior to safely installing and operating the analyzer/ equipment.

  • Page 26: Installing The Mechanical Components

    Installing the Mechanical Components “Part No.” refers to AMETEK Part Number. Installing the Sample Inlet Probe For some applications, you must first connect the sample inlet probe to the analyzer before mounting the analyzer. The same applies if you are installing the probe heater or exhaust tube. Therefore, these sub- jects are discussed before the sections on how to mount the analyzer to the process.
